The GT500 will hold its value alot better than the 15 GT.
2015 with the IRS and a whipple.
Whipple is pointless for auto x. I would go with the 2015
gt500 for sure. Way more potential, and it will hold it's value. A GT will always just be a GT.
I think most of the people here recommending the GT500 either didn't fully read the first post or else they haven't had much experience trying to drive a GT500 fast around corners. The GT500 is a beast but it is not a corner carver by any stretch of the imagination. All that extra weight up front makes it a very heavy steering vehicle. You can use many words to describe it but 'nimble' is not one of them.
Doesnt this go against your Hellcat weight debate? Also, a griggs suspension isnt going to solve the ironblock + supercharger combo the GT500 has (front heavy weight).On a road course you could use a griggs type suspension for the Shelby and not worry about 2015 GT's simply because the Shelby has the chance to use everything to it's advantage.
I agree with you on the GT500 holding it's value, but what do you mean about "way more potential???"
Your forged, and only 2500 away from a 650rwhp car
