Thank you for the reply's guys maybe I should have rephrased the QUESTION.

My first failed diff was due to an inexperienced launch at the pod (AS MIKE SAYS ) smashed the planets to bits and crownwheel

Second diff has failed I think due to over heating on a track day when cold ran fine no loss of traction on the slickes after a few hard laps the inside wheel was spinning up on right hand corners thus giving me no traction place where I have taken it for inspection said it has cooked the plates ?.

Now with out spending mega amounts of money at the moment as ive just forked out for another diff Which might I just add I have no intention of doing any 0-60's or Quarter miles with would a diff cooler of some kind help me in the long run with the plate's failure issue on a track Id love to up grade to an ATB or some other kind of upgraded unit in the future but its just out of my price range for the moment
