Needing some help. I bought my Cobra with Hyperco Coilovers and now buying new wheels. I wanted to put 17x9 with 275, however they are rubbing on them. apparently the previous owner had 17x7or8 with 245 tires on them. Im pretty sure the offset is much differ than stock cobra wheels. I took pictures of the back of the 17x7 but don't know if the numbers back there are any help. I think I may have to change the suspension and go to shocks and springs, rather coilovers. any thoughts?
