hey guys, looking to get new rims soon. Im going to get black fr500s. I was originally going to get 17x9 in the front and 17x10.5 for the back. i was going to put 315s on the back. I also have the borla catback and on the passanger side the pipe already looks like it sits close to the rear tire (245s). Would i F*** something up with going with the 315s out back? should i just go with 17x9 all the way around and just have 275s and be able to rotate my tires? part of me was also thinking of going with 18s in the rear but i dont know if i should go with 18x9 or 18x10. I also have the stock suspension currently and i am thinking of lowering it at some point but only about one inch. would i run into any problems there? some help/insight/opinions would be greatly appreciated.
