We have a Mk6 Fiesta shell with a WRC kit. It's going be Cosworth 4 wheel drive running gear and a Cosworth motor running around 500hp. We want to use a 6 speed sequential box. I've looked at the Quaife one and quiet like them as we have a Quaife 60G in another car and it's never missed a beat.
So my question is do any of you have one and what do you think?

Thanks

Nick
