So today I struck a deal to trade my stockers for some black saleens. The fronts are 18x9 with 245/40's and the rears are 18x10's with 285/40's. Will I need the low profile IRS bolts? Also looking into the h&r race springs to lower the car but will it have clearance issues with the fenders. Plan on 295's later this year but gonna get some use outta these first. Thanks for the input as alway:rockon:
