These shims suit almost every modern BMW from E8X/E9X onwards and help correct the geometry on lowered cars whether you've done it for aesthetics or performance.

This product comes with 4 shims in total to lower the outer pivot point of the factory camber arms and tie rods by 6mm/~1/4" (equal to our E8X/E9X & F2X/F3X subframe bushings)

Due to the Mcpherson strut front suspension design on most BMW's, they have a tendency to lose camber angle relative to the ground when significantly lowered or as the body rolls in corners. This generally results in understeer and/or excessive outer shoulder wear on the front tyres. 
Even with huge amount of negative camber and massive front spring frequencies this is a common outcome on track. 

The shims are a cheap and effective way to correct for a portion of the lowering as well as bring the geometry back towards its intended operating range. Doing so will also bring the front roll centre closer to the centre of gravity for a kinematic increase in front roll resistance by reducing the roll moment. 

This means less body roll, less bump steer and better tyre wear. These shims can be welded to the upright for extreme track/motorsport applications.
