Does this description of a set of rims sound like they will fit an 08 GT? It's for a set of 4 Shelby Redlines. Below is the direct quote from the eBay item description.
"The bolt pattern is 5 on 115 and is 20x8.5 with a +25 offset."
i know im prolly too late. but the actual bolt pattern is (5 x 4.5in) or (5 x 114.3mm).
any who, that offset doesnt sound right either. i think you need somewhere like +38mm for 20s. so hope that helps.
