1. biggers rims will not mess up your rotors. Only way of killing your rotors is shitty brake pads and going thru a car wash after driving for a long time

2. how do u go thru 4 sets of struts in 7 yrs? i'm guessing u do not inflate your tires properly and driving thru potholes like there's no tomorrow. Lots of info on suspension on here, so pls search
