[From a previous post, using Manufacturer-supplied weights/distribution figures]

"Let's say, for argument's sake, the '13 GT 500 scales @ the same Curb Weight as the '12...3820 lb. With it's existing 54-46 weight distribution, that puts about 1760 lb. on the Shelby's rear tires, at rest.

Now, the Curb for a 6-speed ZL1 is 4120...300 lb. heavier...with a 51-49 weight distribution. Of that 300 extra lb., 260 of it sits on the rear tires...

Add [1.85"] of extra tire width (305/35 vs. 285/35, as per Goodyear's specs) and suddenly (!) it's a driver's race...

Too bad PTM 5 didn't include a reprogramming of the front shocks to allow greater front lift for the 1st 2 gears from a dead stop...

BTW, when you add the SVT Track Pack option (not that dedicated 1/4-milers will) to the 500, much of that weight goes where? Yup...the front end...something the ZL1 includes at no extra charge... "

Update: To get a 202 mph GT500, you MUST order the OPTIONAL SVT Track Pack...and its coolers apparently add 30 lb...Track Pack-equipped GT500s Curb @ 3850...TWO coolers up-front, ONE at the rear. Consider the above %s accurate. In this case, the 270 lb. differential (4120-3850) virtually ALL lies on the rear tires...
