Ok so I just got a 99 V6 mustang for graduation with only 12,000 miles (I know right? was it stuck in some kind of time warp the last 11 years?). But anyway, pending a future career I wanna mod the hell out of it. My first priority: suspension and wheels. I plan on getting the eibach pro kit with some racing shocks and struts (not sure what kind yet)...but I want a real aggressive stance for it that i think simply lowering it will not achieve. MY QUESTION IS: Can I put 18s in the front and 19's in the rear? would this cause suspension issues? would it cause any long-term issues at all (tire wear, etc)? What widths would be appropriate? Also, this is a general question, if I lower it and put on larger rims, do I haveto get a castor/camber kit installed to adjust the wheels? I lowered my last car and the camber (or castor i dont know the difference) was so off the tires wore away on the inside in just a few months
