M3/M4 control arm upgrade with the PROPER thrust arm bushing to re-center the wheel in the fender.
Using the M2/M3/M4 front control arms on a non-M car will gain 1° or negative camber and upgrade the inner bushings. This kit includes -
Delphi M3/M4 Front Left & Right Lower Wishbones
Delphi M3/M4 Front Left & Right Upper Thrust Arms
Powerflex Thrust Arm Bushings with Adjusters (pre-installed into arms)
Headlight Regulating Rod and Nut
With the Powerflex bushings in our kit you can correctly re-center the wheel in the fender when using the F8X thrust arms and wishbones. Using the wishbones with off-the-shelf F8X thrust arms will move the wheel forward in the wheel well and likely cause rubbing. This kit is the preferred solution for using F8X arms without changing the wheel position. The Powerflex bushings come pre-installed in the F8X arms.
M2/M3/M4 lower wishbones have a sealed monoball bearing in the inner location. This is much more precise than the rubber bushing used on non-M cars. It's also a slightly longer curved arm that adds 1° more negative camber without any other changes.
The entire package comes ready to bolt on. If you're replacing original hardware, or the factory torque procedure was used, all of the bolts must be replaced (see Related Items below). An alignment will be required with the new camber.
Delphi arms have a two-year warranty.
Powerflex parts have a lifetime warranty!
