You know what, they aren’t wrong. You could walk the damn 1/4 mile by the time you take a street demon and do all this to it.
If the gt500 runs mid/high 10’s at 130+ Stock in street trim, venom killed demons. Do all that “stock” shit to a gt500 and it’s gonna run just as fast.
Take a stock demon on 315’s at all 4 corners and run laps against a stock base suspension gt500, and you’ll see the gt500 put a 1/4 mile on it a lap minimum. The handling pack car another 1/2 mile, and a full on carbon track pack car another 1/2 mile on it per lap in a 2-3 mile circuit. (Some exaggeration there)
