FST Motorsports Chula Vista builds custom off-road and performance vehicles from 842 Broadway on Chula Vista's western commercial corridor, specializing in lift kits, suspension upgrades, and aftermarket wheel-and-tire packages. The shop installs and tunes components from Fox, Bilstein, Rough Country, and CST Performance Suspension, pairing each setup with a computerized four-wheel alignment that accounts for altered ride height — a calibration step often skipped at tunnel-wash facilities such as Super Star Car Wash where post-service cleanup happens without geometry checks. ATV, UTV, and Can-Am side-by-side repair rounds out the mechanical menu, covering CVT belt replacement, axle-boot service, and ECU reflashing for trail-ready performance. Fleet clients rely on FST for coordinated maintenance scheduling across commercial truck and van fleets, bundling brake service, suspension inspection, and DOT-compliance lighting checks into single-visit work orders. Vehicles requiring loaner or temporary transportation during multi-day builds can arrange coverage through EZ Car Rental while lift-kit and body-work projects run their course. Technicians torque lug nuts to manufacturer-specific values using calibrated click-type wrenches rated to 250 ft-lbs and verify wheel-hub runout with a dial indicator before mounting forged aluminum wheels from American Racing and Method Race Wheels.
