alignment and 21's

[lsturbointeg]

i noticed more M5's are sitting on 21's than the 5 series so i wanted to ask for those of you sitting on 21's any issues with alignment specifically camber? i've been told that we don't have camber adjustments? i'm sitting on 21's now but after i lower her on KWV1 coilovers i will be getting the alignment done but was wondering if i'll have any camber issues where the tech will tell me i'm out of luck? appreciate your feedback!
