i used to run a 2 piece agv at the track all the time. i only hit the ground once, but it held up pretty well. i still used it for many a trackday after that. i think i paid $250 for it, but only b/c it was a closeout special. i had to have knee pucks put on it, since it was meant as a "street" suit, but other than that i never had any issues with it.
