Amazing test day
@buttonwillowraceway with
@canyonrunsundays — just grateful to be back out there doing what we love.
Returned after a few adjustments on the stock 2025 GR Corolla (auto).
@808spec Hybrid Coilovers.
Still on stock geometry and ride height, but updated Swift springs to better handle the bumps and “burps” this track throws at you. The car felt smoother and more composed throughout the day.
Tried a bit more rear camber (with the help of Cusco arm) and slight rear toe-out to help stability in the high-speed sections, and switched to a 255/40/17 setup on RT660s (2022) instead of 18s. Also gave the 17x10.5 forged wheels a proper stress test… for those who saw my story, you already know 😅.
We were also battling tire pressures all day — super cold in the morning, then it warmed up quickly, so hot pressures were all over the place. Took a few sessions to dial it in, but we eventually found a nice sweet spot even on the stretched setup.
More than anything, it was good seeing familiar faces like
@relentlessracing , meeting new friends, and just enjoying the track community again.
Big thanks to
@dat_1slowdos — we started this journey around the same time, and it’s been awesome watching him grow as a driver. My role now is just to keep learning, listening, and dialing the car in so he can keep pushing it further.
We were aiming for a sub-2:00 but just missed it. Corner speed felt strong, but we’re still working on finding more top-end speed — the auto transmission is a bit slow on shifts, so there’s definitely room to improve.
All in all, a solid day of learning and progress. Not done yet.
More DIY videos will be coming soon - it’s been back-to-back race weeks getting the cars prepped, and now time to fix a few things up
