OUR SERVICES
Suspension Setup & Tuning for Trans Am Cars
One of the most misunderstood areas of any car build. With so many choices on the market today there is one thing they miss, the geometry. The best chassis in the world is worthless without a properly designed and setup suspension system. Get your geometry right and enjoy peace of mind knowing you got all that you could from your investment. At PFM this is where we shine. Because we race professionally, chassis setup and geometry is what we do daily. We don't just know it, we live it every weekend on the Trans Am Cup grid.
Trackside Support & Arrive-and-Drive
We don’t just build cars — we help you run them at the front. Our arrive-and-drive packages and full trackside support include professional crew, real-time setup adjustments, data analysis, and driver coaching. With years of experience both on and off the track, we can get you up to speed quickly and keep your program competitive all weekend.
