I have a 2005 R53 soon to be on coilovers with a sizeable drop. I am buying 16x8 XXR 530 et 20 rims but am wondering what tire size I should use. I understand an increase in tire sidewall will help with the poor roads in my area. Should I use 205/50/16 or 215/50/16? Will the 215 be too wide with the drop? The coilovers have adjustable front camber plates and I will be ordering adjustable rear control arms. Which is the best set up for me?

Thanks,
Craig
