Our Bump Steer Kit is for the type of person that desires maximum performance from their vehicle. The kit allows you to adjust the tie rod end vertically to optimize bump steer and comes with a tapered stud that fits into the Corvette spindle, so no modification of the spindle is necessary. We include everything shown in the picture along with instructions. Applications: -All FFR GTM kits. Technical Notes: The Bump Steer Kit is designed to be adjusted the same way as a regular Tie Rod End. To adjust the Toe-in of the car, only loosen the inside jam nut and TURN THE INNER TIE ROD. The inner tie rod is a ball pivot and is designed for this. Note, you may need to loosen the outer boot clamp so that the boot does not twist.
