Ground Control Adjustable Bump Tie Rods - E46

Our exclusive GC Adjustable Bump Tie Rods allow bump steer to be eliminated by adjusting the tie rod outer joint up or down with spacers. This kit is similar to the pieces used by BMW Motorsport.  

Our Ground Control kit comes with oversized Aurora aircraft-grade rod ends and all required spacers. 

Fitment Notes:

• Fits all E46s with 17" or larger wheels.
• Minimum diameter of tapered thru-hole in spindle must be expanded to 1/2" diameter with standard 1/2" drill bit - parts can be sent to our shop for the modification, though most home installers with basic tools have not experienced issues.
• This is similar to the pieces used by BMW factory teams in Europe, and they recommend that the rod ends be inspected every session, and replaced if necessary.
