Yup, I've had one for years - 8+.
They are superb, especially if you have the suspension upgraded to make the best of it, and you change your driving style to suit.
I can turn into roundabouts/corners on full throttle and let the diff pull the car through, with no understeer.
Not cheap mind...budget on the best part of £500 on top of the base price for fitting, as you'll need the diff bolt kit too (around £100) and be as well doing a full gearbox overhaul with new bearings/seals/synchros at the same time as the whole lot has to be stripped to fit the diff.
