Important Installation Notes
Test-fit all components before drilling, trimming, or permanently securing any hardware.
Do not fully tighten the mounting hardware until the component has been correctly positioned and all mounting points are properly aligned.
After installation, inspect all mounting hardware before driving. Recheck and retighten the hardware after the first drive, track session, or extended period of use.
Vehicles used on track should be inspected before and after every event. Damaged, loose, or heavily worn components should not be used until they have been properly repaired or replaced.
