kaizman Posted January 10, 2014 Report Share Posted January 10, 2014 I know I am probably going to get yelled at but I have a headache going through all the searches on these wheels and tire sizes. I purchased a set of 20 X 9 Alcoa's (beautiful wheels) for my 2013 GT500. Question ~ I am going to have the rears sent out to be widened and what would be the preferred width to handle 285/35Z-20 Michelin PSS without any clearance problems. I really couldn't find this discussed too much but seeing I am going to widen the rears what do you think the optimum width should be for this size. The car is not lowered it does have the performance and track packages. I assume that I may need to install an adjustable pan hard bar. It looks like quite a few people have installed 265/35Z-20's on the front 9" rims without any issues (I know Shelby recommends 255"s). Thanks for any advice Quote Link to comment Share on other sites More sharing options...
