From its 7,200 square foot shop at Buttonwillow Raceway, 7s Only provides full race car preparation and set up services for all types of race cars from purpose-built to open wheel. From tuning to alignment to complete service and suspension set-up, our experienced mechanics provide top-level service.
When we service your race car, we go through every system, check every nut and bolt from front to rear. We check the calipers, brakes, transmission, struts, shocks, springs and fluids. We check everything from differential torque to tire wear.
Why not test and tune your car before the race to maximize performance?! With our state-of the art DynoJet chassis dyno, we can quickly and accurately diagnose performance problems and help you solve them.
Your car's suspension geometry is critical to handling and performance on the track.From alignment and corner balancing to setting camber, caster and toe, we'll make sure your car is ready for whatever track you're running. 

Last, but not least, is what we call "driver set up". Often overlooked is the impact that poor driver set up can have on lap times. Are you too close to the steering wheel? too far away? Can you heel/tore? Do you have a usable dead pedal? You'd be surprised that making even minor adjustments to your position in the car can drop 10ths of seconds from your lap times!
If you want to win, you need a car that is prepped correctly. Too many drivers go to the track with a car they "thought" was prepped, only to have something simple fail and take them out of the race.
