About RZ1USA – Performance Engineering for Track & Canyons

WHO WE ARE
RZ1USA is a Southern California performance outfit led by Riz - ex-pro racer, engineer and the driver behind the VB500 SuperGT. We build cars to carve canyons and crush laps: balanced power, race-bred chassis tuning, rock-solid driveline, cooling that survives desert heat and grip for days.
What We Build
Our flagship is the VB500 SuperGT (2022 Subaru WRX):
389 whp / 416 lb-ft in its current reliability tune (peaks of 430 whp / 460 lb-ft on the dyno). It’s engineered for handling first, not drag clout-sequential shifting, motorsport brakes, aero that works and suspension that reads the road.

CruzeNrideZ - The Community
We host CruzeNrideZ, a SoCal canyon run / touge culture crew for real driving enthusiasts. Fast, but smart. Rules are simple: no lane splitting, share the road, watch for oncoming traffic, cyclists, bikers, hikers and wildlife.
Exact meet details drop on IG.

BACKGROUND
With a racing heritage rooted in professional driving and race car development, building Project WRX - now the VB500 SuperGT; has been one of the most rewarding challenges of my career.
The vision was clear: create the ultimate fast road and track car, not a dyno number chaser. Reliability, longevity and drivability were the top priorities. Every component was chosen with purpose - from chassis balance and driveline strength to cooling systems designed to thrive in SoCal elevation shifts and desert heat.
Bringing Project WRX to life has been more than just a build; it’s proof that performance cars can be engineered to inspire confidence and excitement every time they hit the canyon or track. My hope is that every driver who experiences the VB500 SuperGT feels the same thrill that went into building it.
