Upper Control Arm Difference
Are the upper control arms between the competition and the non comp cars the same? I see that there are 2 different types. 31-12-7-849-503 for the -20mm camber and 31-12-2-284-980 for standard camber. I know CarBahn and Dinan also make upper control arms.
Sounds like the -20mm arms are a factory upgrade but I want to make sure they didn't come stock with the competition package. |

Non-CP and CP use the same UCAs. As far as anyone can tell, the Dinan/Carbahn arms are just rebadged versions of those other arms you found. I believe there's also a +20 version and the original intent of either is to get a damaged car back within front camber specs.
Btw, I believe it's 20 minutes of camber, or .33 degrees. |

BMW had 3 different arms for camber correction.
They have aftermarket camber bushings. I think kmac makes one.
