I am looking at a new diff for the Mk1, has anyone used a Wavetrac Item? The main problem with a Quaife ATB is that if you lift a wheel you lose all drive, the Wavetrac item continues to output in such conditions?
No used one yet but going to try one in a corsa VXR and astra VXR soon, they seem to offer all the benefit of a plated diff and the benefit of an ATB! If they are as good as they say then they will be a very good purchase!
Silky smooth in operation, applies power to the ground very efficiently, feels quicker off the mark and has removed the 'power on' understeer in corner.
