Quaife diff any good?

[Nigeyboy]

As it says really.

I am pondering a few options to help improve/fettle the T350 (and probably waste some cash...). This went through my mind as the diff casing has a covering of rust and I'd love to get it off one day and clear the rust off and make it sparkly. I thought if it was off would I change the diff?

Has anyone seriously considered one / fitted one and what difference would I notice over a Hydratrak diff?

Depends how you drive. Do you regularly track the car or race in sprints/hillclimbs? If not then its probably not worth the money. If you do then it is probably a worthwhile upgrade.
