I think the MR2 will be a good ITB car, but am no way convinced it'll keep up with the Golfs in a sprint race. One area I think it has big potential is in enduro races. While I've only seen the tire wear on a 7" rim, I do not imagine it would be much more on a 6" rim and those things last forever! Same with brakes. All this giving a nice advantage in the pit race.
