    Bump-Steer Kit
    Installation Instructions


    Note: An alignment will be needed after the installation of the Bump steer kit.

    I. Parts Included in Kit:

    11270 ROD END EA 2.00
    11271 SLEEVE, OUTER TIE ROD, THREADED BOTH ENDS EA 2.00

    12089 JAM NUT EA 2.00
    11269 BUMP STEER KIT INSTRUCTIONS EA 1.00

    II. Tools Required:

    Jack Stands
    Floor Jack
    Tire Iron
    15/16 inch Wrench
    ¾ inch Socket or Wrench
    Adjustable Wrench
    5/8 inch Drill bit
    Drill
    Pliers
    ½ inch Allen Key
    Hammer

    III. Installation Instructions

    1. Jack the front of the car up and place on jack stands.

    2. Remove the Front wheels

    3. Using a pair of Pliers, remove the cotter pin from the Tie Rod ends.

    4. Remove the Crown nut using a ¾” wrench

    5. Use a hammer knock the Tie Rod ends out of the Spindles.

    6. Use an adjustable wrench and a 15/16” wrench to loosen and remove the Tie Rod ends.

    7. Drill out the hole for the Tie Rod end using a 5/8” drill bit, make sure the hole is straight. Take your time and drill slowly as the spindle is very hard and will dull a fast bit. Note: It is a lot easier and faster to take the spindle off and use a drill press to do this.

    8. Wipe the spindle clean.

    9. Screw the new outer Tie Rod Arm onto the Inner Tie Rod Arm approximately 1¼”.

    10. Screw the Rod End into the new Outer Tie Rod Arm approximately ¾”.

    11. Insert the 5/8 inch bolt from the bottom through the spindle and then the rod end. The rod end should be on top of the spindle.

    Note: An alignment will be needed after the installation of the Bump steer kit.

    12. Use a ½ inch Allen key and a 15/16” wrench to tighten the lock nut onto the bolt.

    13. Mount the wheels on the car.

    14. Using a jack, return the front of the car to the ground.

    15. Take the car to an Alignment shop. The Specifications are below.

    Alignment Specifications:

    Camber: -0.5 degrees (street) to -1 (race)
    Caster: 3 degrees
    Toe In: 1/16” total


    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,
