I love to know the sprocket count the ZX-10 is running, even at 175hp, there's no way it's stock. Also, the RX-7 is running a 'vette engine, and the guy can't keep off the redline and e-brakes like mad. I used to be in the drifting thing, e-braking is really only used for extreme hairpin drifts and turn arounds, not every single corner. With the 'vette engine up front he shouldn't have to e-brake or bounce the rev-limiter. Kudos to both for a great vid, but the RX-7 could have done a LOT better IMO.
