A local fellow has 2 2007 GT 500s that he has a ton of leftover parts for sale after sending 2 new cars to Las Vegas for Shelby upgrading....I am interested in upgrading to his new tires with 50 miles on them with Shelby rims.Sounds like he wants $1200 .Basically paying for four brand new tires and getting 4 Shelby brand new rims for free.Also has 2 front spoilers that I would like to put on my car.My questions are.....#1...Is the price fair which I think it is??? And #2 Will the wheels fit? Also #3Are they wider than my tires???....#4...Will the GT 500 front spoiler fit my 2007 GT???
