Introduction
Every race car has a story, and our goal with these build overviews is to pull back the curtain a bit and share the why behind each one. Not just the spec list or the shiny parts bolted on, but the decisions that shaped the build, the lessons we learned the hard way, how the car performs today, and where we’re taking it next. Think of this as a guided walk through the full journey — the good, the bad, the breakthroughs — so that whether you’re dreaming up your first build, refining a current project, or planning something wild for the future, you’ve got real-world insight to draw from. And hey, if any of this sparks ideas or you’re curious about building a similar car, we’re always happy to talk shop and help you get pointed in the right direction.
How We Ended Up in a Nissan 370Z for Touring 3
Our path to campaigning a Nismo Nissan 370Z in SCCA Touring 3 didn’t start with a Z-car at all — it started with a fleet of BMW Spec E46s and a once-in-a-lifetime opportunity.
Back in 2021, the SCCA Runoffs were being held at the Indianapolis Motor Speedway. That’s bucket-list territory. There was absolutely no way we were going to miss the chance to race at Indy, so we brought our Spec E46 drivers and cars and dove into T3 with both feet.
That first year was awesome. The SE46 was decently competitive and, with a 2,950-lb minimum weight in Touring 3 (vs. 2,850 in the spec class), we still felt like the platform had room to grow. We were optimistic.
But 2022 at VIR changed everything.
VIR is the polar opposite of Indy when what matters most is top-end speed. And in T3, you simply cannot hide from that reality. While the front-running cars were consistently touching 138–140 mph top speeds, our Spec E46s were essentially tapped at 136 mph, and in reality at VIR, we were barely seeing 132 mph with a draft.
So even if the chassis could somehow theoretically match the lap times, the racing wasn’t viable. It was a harsh reality check, but a necessary one.
Time for a Change
After the 2022 Runoffs, we evaluated realistic alternatives:
- BMW Z4 M Coupe
- Nissan 370Z
We also had a 2010 Porsche Cayman PDK ready to build, but the timeline and development curve didn’t match our Runoffs schedule.
The turning point came when a proven, nationally competitive T3 370Z changed hands and landed with our friend Chris Hart. Suddenly, we had access to race-winning data and real experience. Combined with the 370Z’s double-wishbone geometry — perfect under T3’s 3.5-degree camber limit — the choice became clear.
Buying the Car — A True Nismo
In mid-2023, we bought a 2011 Nissan 370Z Nismo — a true, original-owner Nismo.
Because the shop was at max capacity, the entire initial teardown happened in the driveway. Full interior strip, seam sealer removal, weight reduction — everything. We delivered a perfect rolling chassis to Fabtek for a cage that matched Chris’s championship-proven design.
Cage & Safety Fabrication
Once Fabtek completed the cage, we resprayed the interior in OEM Nismo red and began the race against time to assemble the car before the 2023 Runoffs at VIR.
2023 Runoffs — The ABS Reality Check
We made it to VIR… but the first test day exposed the 370Z’s biggest flaw: its factory ABS logic.
We experienced full-on ICE mode, where the ABS system dramatically reduces braking pressure unpredictably. It ended our Runoffs before the weekend truly began — but thank God, the car and driver were safe.
Post-Runoffs: Fixing the Brakes
That failure changed everything. We went deep into:
- pad compounds
- rotor configurations
- wheel-speed ratios
- heat management
- master cylinder behavior
- ABS trigger logic
We broke things. Tested everything. Logged everything. Even pushed for rule adjustments when needed.
And now? The brakes are one of the absolute strengths of the car.

Racing & Driving Highlights
???? 2024 Hoosier Super Tour Win — NOLA Motorsports Park
The car’s first national-level win (but technically a P2 due to post-race adjustment). New track, technical course, colder weather and still figuring out the brakes.

???? 2025 CAT Majors Win — Road America
90°F, extreme humidity, and the car delivered a dominant run once we were in clear air.

???? Global Time Attack — The Ridge Motorsports Park
Unrestricted laps on Yokohama A052s showed the Z’s true potential.

What We’ve Learned
- The car loves mechanical grip.
- Weight distribution & stiffness tuning are critical.
- The ABS and braking system is both the biggest weakness and the biggest opportunity.
- Heat management is everything in longer races/sessions and when air temps get above 80F.
- The Z rewards smooth inputs and stability.
- Parts availability is excellent with the right partners.
Future Direction — Where #109 Is Headed
- More engine & cooling refinement
- Testing Paragon PA015 big-brake upgrade
- Further alignment/tire data development
- Weight management improvements
- Full prep for 2026 Hoosier Super Tour + Runoffs
