[Stancelife101]

alright so I just got an e36, whoopty shit just another e36 build I know, but im 18 and need help. I ordered bws coilovers, should be at my house next week... awesome. So Im also getting some wide wheels for the rear, I know im so different. The offset is low and I do actually need to run -8/ -10 camber to not mess up my fenders to bad. So can someone hear give me a straight forward answer on how to achieve that much. I know control arms but what kind actually go that far, all I see online is rca that only go as far as -1 I need camber and I need help!
