If people could give me advice based on their experiences that would be much appreciated
Many Thanks

What sort of usage are you intending for the car?
How long has your current diff lasted with the current power level?
What sort of concessions are you prepared to make with noise if you do use it on the road?
Also, maybe worth reading these 2 threads as it may well help you with your decision or at least give you some background
