I'm getting ready to put a lift on my 2011 and I am wondering if I can still use an aftermarket 20 inch rim on the kit. Reason I ask is because it calls for a 17x9, 4.5 inch backspace with 35's. I was just wondering if I would run into any issues with running 20 inch rims? Also is there anything else I need besides shocks, such as the driveshaft alignment kit? Thanks!
