I've driven all manner of other people's Cossies, and the nicest of them all was an Escort Cosworth with around 350bhp, Quaife big tooth box, Quaife ATB thickwall front diff, and a 50NM centre VC, using a B&M Quickshift
Quick as fook, no lag to speak of, comfort in knowing the transmission won't go pop, great traction, just an all round nice car.
Stage 3 hits the spot IMO
