I want to put some 17/9.5 front and 17/11 rears on my 88 camaro but ive been told that I'm going to have to modify parts the car to make the 11s fit. is this true? if it is what are the widest rims i can just put on without having to do any extra stuff or spend extra money?

im only 16 just got an 88 camaro with 305tpi as my first car so i dont know much about cars yet...
