Tell me, just how much do you know about performance and gear ratios? Because the reality of the matter is, the Chevy 12 bolt rear-end in that car (I believe that's what it's got; anyway, that's the best chevy had in their cars; so this is all best case scenario) not only can't handle a lot of power, but the gear ratio's available are not that low to be able to compensate for a 200% increase in tire diameter. I'm raising the BS flag on that one; even if he had a 500HP engine under the hood, getting gearing that would allow the power to put put to the ground in a even semi efficient manner would be next to impossible. Even if you could, a couple runs with solid hook up and you'd grenade that POS chevy rear-end.
Lets be honest, a car like that is show; not go. Plus, you're just asking for axle wrap like crazy; it would be the equivalent of drag racing a truck with a giant lift and mudders. Sure, for what it is it MIGHT have some balls, but it will still be a slug when you get it next to that tree and punch the gas on the last yellow.
That BS isn't fooling anyone
