This is so not going to happen. I can understand that you're new to the world of drifting. But drifting is not and never has been about speed. Therefore the argument of drift vs grip is totally useless and been done to many times to count. Do a search on the GT3 Drift forum if you want to see a thread about this.
Grip is faster then drift. Period, it's called physics. Sorry, that's just how it is. But since drifting ISN'T about speed, it doesn't matter does it?
