RacingDiffs Differential Backlash adjustment shim kit 188mm for BMW

If you are looking to install a Limited Slip Differential (LSD) into your BMW differential, or change the gear ratio, then you will most certainly need to adjust Backlash and Carrier preload.
In order to do it properly, this kit is a must-have.

This set contains 10 shims, in the range of 1 to 2 mm thickness, each increasing by 0.1 mm, therefore unlike other sets on the market, RacingDiffs set allows you to adjust your diff with an unmatched precision!
Backlash adjustment is critical. If not done properly, a whining noise and the crown gear damage will inevitably occur.
