The diff is put together better internally. There are 8 cogs that move completely different to a standard diff. This makes it better because it creates less play, therefore the power can be put down faster. It is also made of steel so it is hard to break.
most people put them in the front and it is a straight swop but you have got spider diffs they are better than standard so to be fair phil you have no need to put a torsen in i do not think you would be able to notice any difference in performance on our track
That was a very tactful way of putting that it wouldn't make any difference to Me - and you're probably right, been off and googled them - clever bit of kit - putting traction to where it would work - ideally suited to Truggies.
