I picked up a set of 35.1250 17 KM2's for a steal on craigslist and am looking to wrap them around Raceline Renegades 6 that are 17x9's and have 5' backspacing. I am looking at 3 inch keys for up front and 2 inch blocks for the back and i dont mind trimming some.. Any opinions on if this is a decent idea? lol.
