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 my need to loosen the outer boot clamp so that the boot does not twist.

These are "old" instructions! You no longer drill out the spindles!!!!!!! Ffr supplies you with nice sleeved bolts instead of the 5/8 bolts as described above. Trust me, i learned this AFTER drilling out my spindles. The good news is that i am gonna be able to buy 5/8 grade 8 bolts and not have to buy new undrilled spindles.

Hi Dave,

Are these instructions for any FFR car in particular for just general "how-to" steps? I bought the bump steer kit for the GTM a while back, and will be installing them soon; (before I do the final alignment).

Thanks,

Mike
