I'm trying to find out what is the biggest slick that will fit a stock frame 87 gn i have the fender lips rolled but am looking to install a set of draglites in the new year and am looking for opinions on slicks. I ran a set of 28 x 9 no problem and have a line on a set of 28 x 10.5 but think they might hit the frame I'm using a set of 15 inch centerline rims with I believe 3.5 backspacing just looking for opinions. Draglites to come next season........
