96slowbra Posted April 27, 2013 Report Share Posted April 27, 2013 i have a 2010 gt500 with a griggs gr40 suspension system. i am not an avid drag racer, but i like to go to the strip with my friends. i run a pair of stock 1994ish gt rims (16x7) with some et streets when i do go and they fit fine. i opted for the '315 kit' on my griggs set up, but i feel like the bottom of the coil-over would interfere with a 15" rim. i would like to run a pair of rears for drag racing that are 10" wide, but afraid to pay the money before i know they will fit.

msb64 Posted April 28, 2013 Report Share Posted April 28, 2013 Not sure if you might encounter a clearance issue with your Griggs suspension, but you definitely will have to install some rear swaybar relocation brackets to be able to fit a 15" wheel in the back. For the strip I ended up running some M&H 325/50R15s on Racestar 15" x 10" wheels. I also did the upper bumpstop bracket removal and bumpstop relocation as well though, for extra clearance back there. Those 325s sure give it a nasty look. http://www.autoclubs.ca/gallery/2012/120825a/img_7102.html Link to comment Share on other sites More sharing options...
NMAv Posted May 9, 2014 Report Share Posted May 9, 2014 96slowbra, did you end up buying the 15 inch wheel? Wondering how you made out. I'm in the same quandary. Link to comment Share on other sites More sharing options...
