I just looked at the SCCA web site at the ITR rules and it says only 89-93 Mustang GT and LX Mustangs. There is no mention of hatchback vrs notch. Both cane with 5.0 v8s and all suspension & drive trains were the same. Same brakes, rear end, transmission. It didn't mater if it was a hatchback or a notch. I owned 3 different Fox Mustangs and raced a '93 Cobra R. I thing I know what I'm talking about.

Saying that I do agree that the 94-95 GT may be a better choise for ITR. Stiffer chassis, better suspension & brakes stock, and can run at a lighter weight. Cost of these cars is not much higher then a 5.0 Fox. A Fox in good condition is now holding its own price wise and may in the future go up a bit. I know a stock 5.0 notch in good condition can command a price higher then a stock GT.
