Track Walk: The Ridge Motorsports Park

Welcome to The Ridge!  The Ridge is the newest track in the Pacific Northwest that is generally available to the public (Vancouver Island Motorsports Park opened recently but is a private track).

Similar to the Portland International Raceways (with a Chicane) track walk, we’ll use the Track Attack #209 PRO3 race car, a relatively low powered “momentum” car, to illustrate how to get around the track.  The session data we are  using for this is available here on Track Attack – feel free to request it.

We’ve also broken the track down into 6 segments, each segment is defined right before the major major braking/slowing down zones.

Braking a track down into sections, makes it easier for people ‘consume’ it and prioritize where to get focus.

Before you read on, watch this complete lap from a dry race in September of 2017.  Read the article and the re-watch the video.

Segment 1: The Uphill

This segment starts at s/f and goes all the way up to the first major braking zone (not including braking for T2) entering the Carousel.  The first thing here is that this segment is a 76ft climb in elevation.  The equivalent of an 8 story building.  Yeah.  So every single loss of mph as you make your way up the hill, will be penalized with a multiplier as you go uphill – keeping the momentum going is a top priority.

Momentum is important – check!  Turn 1 – get ready for a trouser check.  Turn 1, in some cars, can be taken flat, without lifting.  This is similar to T1 at Spokane but the distance between T1 apex and turn-in for T2 is not as long, so in cars that are faster than a Spec Miata, experiment with caution.  Personally, the most I’ve ever been able to get away with is a ~4/10 braking effort – just a tad more than a brush of the brakes, go back to tad of maintenance throttle and then back on the brakes, about the same amount for the downshift to 4th gear and then going back up the hill.

As you get the car past the apex of T2, it’s really important to get close to the curb of T3 but don’t take too big of a bite off of it, as it will send your car back to track-left, which is not the ideal line for the remainder of the complex.  Once you get to full-throttle, you absolutely cannot lift.  After T3, stay track-right, to setup a wide arch into T5 and then release the car to driver’s-right.  This whole time between T3 through T5, when you’re pinned to full throttle, you will feel the back end wanting to step out.  That’s ok – simple counter steering corrections (small ones), while staying flat, will take care of them.

After this, it’s smooth sailing to The Carousel – find a straight line to follow, that will set you up on track-right, for T6 (The Carousel), which is a long, flat left-hand sweeper.

Segment 2: The Carousel

This segment is just one corner.  Why?  It’s long and hard to get right.  This corner can be taken many ways but here is one that has proven well in racing and qualifying conditions.  Set yourself up track right but not necessarily right on the edge of the track.  Brake a little later than feels comfortable with a solid 6-7/10 effort and after the initial bite, start trailing off and turning into the corner, like if you were trying to double-apex the corner.

The backend may start to come out as you turn-in so get ready to catch the backend with some maintenance throttle.  Try to keep the car tucked in tight to the inside edge of the corner and if it washes out a little mid-corner, that’s ok and that just means you can back on throttle even more aggressively for corner-exit, because you don’t need as much steering input.

Don’t mind what looks like me driving off the course, that’s just a natural occurrence of margin of error of GPS signals and the stitching together of satellite images for maps.

About 35-40% through the corner, you want to be on-throttle and free here on out, you don’t lift.  Start your ascension to full-throttle and as you feel the backend come out, pause the throttle application and give it a steering correction but DO NOT LIFT!  For me, there is a single, tall tree out in the horizon of this corner and the instant I see that tree, I go full-throttle, no matter where I am.

From here, let the car release all the way to track-right, the very edge if needed.  A lot of people don’t get out here because they want to setup far left for the next segment and that’s a trade-off you can decide to make.

Segment 3: The Thumb

This is one of the trickiest parts of the track.  It combines a big compression and low-speed traction event at 8a and 8b but also a super hard, decreasing radius turn at T11 (aka The Thumb).

As you come out of The Carousel, it’s ok to stay driver’s left and then draw a straight line as you go downhill at 8a.  Stay on throttle until right before you feel the ground fall away, lift and synchronize the compression event with your braking.  When you do this right, you don’t need to brake as hard because the compression event gives more bite to front-end.  Downshift (if you have to), wait for the car to rotate a tick and then get back to maintenance throttle.  You want to get on full throttle here as quickly as you can but the sliding plus the acceleration means that it will be really easy to get on-power over-steer, so be aggressive but careful with your throttle application.  After you get to full throttle, it’s a full throttle ride all the way up the hill, which is another 36 foot climb (almost a 4 story building).  Every mph you unnecessarily drop or every split second of having to lift from throttle, will make you pay dearly at the top of the hill.

Where you brake for the thumb will be determined by the car and how fast you’re going.  In a PRO3 car, the engine is spinning at 6,500RPM and ~103mph and we wait to come off throttle just before the curbing on the left and are well into the brakes at those curbs.

You don’t need to track all the way to driver’s right to setup for the thumb, about mid-track is fine in most cars.  Next, is one of the hardest corners to get right – find the late apex and make it your job to hit that curbing with your LF tires.  Getting on those tires, in 3rd gear (in many cars, 2nd gear in Spec Miatas), means you can get on the throttle hard and have plenty of room on the exit of the corner.  Be ready for the car to wash out and go on the exit curbing and maybe even drop a rear tire on the exit of the corner but that’s ok – DO NOT LIFT!

Segment 4 & 5: The Ridge Straight

I’ve broken this segment into two segments because it contains two corners, which are taken very differently and I wanted to leave the last segment being the last corners before the front straight away.

First is the very deceiving Turn 12 right-hander.  It’s deceiving because you can actually car a good amount of speed here and the corner opens up quite a bit on the exit, which means there is a plenty of room for corrections if you maybe got on-throttle too early.

The trick here is to get to the apex and be on full-throttle at the apex.  There is a bump or bulge right at the apex, which will feel like it kicks your car away as you hit but get to full-throttle, stay in it and ride it out.  You’ll almost for sure have the car sliding a little just past exit – a simple steering correction will get it back under you and you can keep going.  Then start making your way over to track-right, to setup for the Ridge complex.

As you approach the corner, you’ll see that the ground starts falling away in the middle of the braking zone – YIKES!!!  This means you have to have your heavy braking done before the ground starts falling away.  Looking at the data, the drop-off is a 7 foot decline in elevation over a 150 foot distance.  150 feet when you’re travelling at 75mph, goes by pretty fast, so this is a split second decision.

As you approach turn-in for the corner, stay on the brakes ever so slightly, so that when you turn in full, the noise is loaded up and will help rotate the car.  It’s ok to bite off a little bit of the curb but don’t get over zealous.

Give it some throttle as soon as you get past the corner, turn for the right hander and stick to track-right as much as you can.  If at all possible, stay off the brakes but you might need to brush the brakes to help the front-end bite.

Segment 6: The Front Straight

The lap is almost over!  You’re barreling down the Ridge Complex, a nearly 80 foot drop and you need to decide what to do for the last corner before the main straight away.  There are couple school’s of thought:

  1. Geometrical fastest line: Swing out wide, carrying more speed because you have a wider arc, a single late apex at Turn 15 and then pin the throttle down until start/finish.
  2. Shortest distance line: Stay a little closer to the inside, use the banking in the corner, travel less distance and hit the apex of Turn 15 at the same spot.

This really depends on what kind of car you have and the track conditions on the outside of Turn 15.  In race weekends, that wide line isn’t used much, so there ends up being a lot of marbles out there.   Great for the rain but not for the dry.

At least in a PRO3 car, we have more grip than power, so as is with many of the other corners, the less distance we have to travel, the better so Option 2 is what you’ll see in the data.

Now, I can totally see an argument even for a PRO3 car to setup for a single flying lap to go super wide, throwing away the lap time for that current lap and setting up for a higher top speed going into Turn 1 or even setting up a competitor for a pass at the end of the straight.

You’ll see in the data that I’m on throttle about mid-corner and full-throttle at about 3/4 of the way of the corner.  After that, it’s about finding the straightest line possible through Turn 16 and the least amount of steering input all the way down the front straight away.

Conclusion: The Ridge is awesome.  Go drive it!

The Ridge is really a fun track.  Newer and well take cared of pavement and plenty of run off room in most corners.  You can get in trouble and it makes you pay but most of the time, it’s dirt and rocks on your car to go along with a bruised ego.

The facilities are constantly improving and with a motocross and a kart track that is a mini version of the big track, there’s few places that can compare.  The downside is that it is located about 30 minutes northwest of Olympia, WA and Shelton has limited hotels but coming out in an RV or camping, is an absolute blast.  Best of all, there are no drag races so every evening, you can do a complete track walk.

Track Walk: Portland International Raceways

In a couple weekends, we’re headed back to Portland International Raceways and the first time I’ll get to drive the track for more than one session (in real life) this year and since I was on the Speed Secrets Podcast, earlier in the spring.  I got some live coaching from Ross Bentley and have been excited to implement the tips I heard.  Check out the podcast episode here and subscribe – it’s an awesome podcast with a wide variety of guests and every time, I learn a ton.

So let’s take a lap around the track and go through each sector as defined by the sectors on Track Attack.  Below we’ll be using illustrations from real data from a pair of front-running “spec” racing class cars: my PRO3 and Will Schrader’s Spec Miata.  Both are considered low-power momentum cars but there is enough power and weight difference you’ll see different things happening.

If you are a Spec Miata or PRO3 driver in the Pacific Northwest (or have similar cars), you can request to join the respective teams on Track Attack and get access to the session data that we’re using in these examples. (Link to PRO3 data share team and Northwest Spec Miata Tour)

We’ve broken up PIR w/chicane into 4 sectors.  Each sector is a combination of corners and are split halfway through a ‘straight away’.

Elevation change: None

PIR is like the Lime Rock Park of the west coast.  In the chicane configuration, there are 7 right hand turns, compared to 2.5 left hand turns.  But unlike Lime Rock, the elevation change is near zero.  Check out this video where the data overlay shows the elevation change – there is just under 10 feet of total elevation change.

No real elevation change but there are still some tricks on banking that the track holds.

Segment 1: The festival chicane

The first segment starts at the start/finish line, of which the speed that is carried before the first braking zone is determined heavily by the exit out of T12 on the previous lap and if you might have caught a draft down the front straight.

Braking for T1 will depend on the car and whether its a qualifying lap or a race lap.  In a PRO3 car and a qualifying lap, you can hit the brakes hard right after passing the 400 board and what ends up being right before the 300 marker.  Note, this is hard to replicate lap after lap.  After hitting the brakes hard, start coming off of them and you should already be looking for the apex of T1.  It’s a good practice to put the right-side tires on the FIA curbing at the apex of T1 and even dropping a tire inside of the curbing isn’t bad but puts more stress on the suspension components.

Think about this: When are you releasing the brakes as you enter the corner for T1?  Play around with that.

You’ll want to take a line where you can hit T2 with a late apex.  Why?  There’s a decent straight-away from full-throttle at the exit of T2, all the way until T4.  Focus on doing what you can to get to full-throttle as soon as you possibly can coming out of T2.  Usually when I see data of someone really moving through this segment, it is all about the minimum speed they carry through T1 and how quickly they can get to full-throttle out of T2.  Clearly, there is a trade-off here but that’s the trick – finding the right balance and compromise for you and your car.

Also, the steering input for the change in direction to turn for T2 is relatively abrupt and hard.  Remember, slow speed –> fast hands, fast speed –> slow hands.

Comparing the lines of two front-running cars: Blue is a PRO3 car and Yellow is a Spec Miata.  What differences do you see?

Segment 2: No rest – Attack!

Segment 2 includes T4 – T6 and is one of the areas that separates good from great laps.  It can be easy to coast through this segment, but when you’re looking for the maximum lap time, you need to attack!

Same two cars: Yellow (Spec Miata) and Blue (PRO3). There is a 250-400lbs weight difference depending on the Spec Miata. Why do you think each car may be taking different lines?

T4 is somewhat of a false apex – you don’t absolutely have to hit the curbing but the benefits of staying closer to the curbing is that you travel less distance and you have more room to catch the car, if and when the car is upset by the bumps.  When you brake depends on your car but generally speaking, with the chicane, you can go pretty deep into the braking zone and brake pretty lightly relative to braking for T1.

Think about: As in segment 1, when are you coming off the brakes as you enter T4?

As you dive into the T4, the rear of the car may start sliding, which is a good thing!  Use maintenance throttle to settle it down and slowly start going to full throttle or modulating accordingly.  How much throttle you can give it will depend on the speed you carried through mid-corner and how well the rear-left suspension components are absorbing the bumps.  There is a lot of load on that rear-left, all the way through the exit of T5.  Is your suspension bottoming out?

As you approach T5, you’ll have to either breathe off the throttle to get the car to rotate or give it some very slight braking.  Get turned in and hit that curbing for T5.  Then give it as much throttle as it will take and let the car release to the driver’s left as you approach T6.

T6 has different schools of thought.  One school says sacrifice the corner and run the shortest distance possible.  The other says that you should hit the corner with a wide entry and get an amazing run towards T7, where you don’t flare out as much on the exit of T6.  I’ve seen data from both approaches and it’s really a toss-up.  Find what works best for you and your car.

Just remember that the outside of T6 is off-camber and usually has a ton of marbles.  You don’t want to be caught on the outside of T6 almost ever (save for rain) it will be slow and you will get passed.

Going fast through segment 2 should feel like you are on the ragged edge, having to catch the car slightly throughout the entire complex.  This is no time to rest – attack!

Segment 3: The banana straight!

In my opinion, this is the second most important segment of the track.  T7 leads onto the longest “straight” on the lap, so getting onto full throttle, without backing out is the most important thing here.

Where you determine your braking point will heavily depend on your car but the goal should always be to be at or near full throttle right at the apex of T7.

Can you see the ever so slight differences between the PRO3 (blue) and the Spec Miata (yellow)?

Think about: Where are your eyes when you are on the brakes for T7?  Get them on the apex as soon as you possibly can.

Use one fluid motion to get the steering input for the corner and when you are pointed at the apex, commit and get to full throttle as quickly as you can.  In all of my fastest laps, I have a healthy two tires on the T7 curbing and will have a slight slide on the exit, of which a quick steering correction will get it to stop and doesn’t require a lift.  Over slide on the exit or have to lift after apex and you are dead in the water.

Segment 4: Brown trousers

In my opinion, this is the most important complex of the lap.  It is the scariest and thus, even among good drivers, there is more variance in segment times than in any other segment.

The entry into T10 is the most important and it is much less about how late you can brake and more about how well balanced the car can be, as you carry a higher amount of speed through the corners.

Think about this: Will a car that is stood up on its nose because the driver braked super late, turn better than a car that is balanced front to back because the driver braked maybe a little earlier and lighter?

Some drivers can pull off (in a PRO3 car) braking at the 200 marker and keep the car balanced and others brake at the 300 and it works just as fine.  Figure out what works for you and your car.

Make it your job to always, and I mean always put tires on the drivers-left curbing of T10.  Then make as a straight of a line as you can to brake in a straight-line for T12.  This means that you might miss the curbing on T11.  That’s ok!

Brake in a straight line for T12, focus on when you’re going to release braking for T12 and get just like T7, get your eyes to the apex of T12 as quickly as you can.  Turn in with a single, smooth movement and just nibble or have a full tire on the curbing of T12.  This is slightly less important but if you do this, you’ll know for sure that you’ll have enough track on the exit and avoid hitting the tire walls for the drag strip (of which I’ve hit) or along the main wall.

As Ross suggested during the podcast, the goal is to get to full-throttle as quickly as possible.  If you find yourself near the apex of T12 and at 50-75% full-throttle, just give it the beans!  Go all the way and know that it might slide a little on the exit but you usually don’t need to lift to stop the sliding – a quick steering wheel correction will be plenty.

After that, it’s smooth sailing to start/finish.  Release the car and have the lightest hands on the steering wheel as possible.  Any steering input while at full-throttle is friction and friction means going slower.

Other things to consider

People say that Portland doesn’t use up brakes and tires and that’s sort of true but when you’re pushing, everything makes a difference.  Using the curbs is really important but also has led to pad knock-back for several drivers, which isn’t fun.

Track temperature makes a huge difference on available grip and can swing 20-40 degrees from the morning to the late afternoon.  That could make a difference of up to a second on lap times or more.

Catching a draft can also make a huge difference, upwards of .5 seconds on a lap.  So if you can get a tow early on the main or back straight aways, do it!

Track records are made on <100F surface temps, <80F air temperature, fresh tires, qualifying weight, a draft and putting it all together on the first 2-3 laps of a session.

That’s it!  Let us know what you think about the guide and feel free to comment and share any of your tips and tricks for PIR.  Do you do different things?  If so, share it and tell us why.
