Just took delivery of my 2011 GT500 and headed to the Mid America Ford Performance Meet and would like to slap some drag radials and other wheels on the back to see what it will do.

Question is: I've also ordered 14" Front and Rear Baer 6-Piston Brakes for the car so I want the wheels to clear the calipers. I know that an 18" is the smallest option, so I was wondering if anyone has the hookup on available wheels and drag radial combination that would work.

The 2011 GT500 comes with 285/35/20 tires which have a rollout of 87.49. I would like to stay near that number or smaller.

I'm in a major metropolitan area and not sure if I will be able to get these in time or not, but would like to take a shot. Anyone have some specs?????

Thanks
