The ball diff on the other hand is pretty flexible. As this track that I'm going to race on has fast sweeping corners but with not much traction, the front ball diff is more beneficial to drivers of my calibre ! 
Just my 2 cents.
Hey guys.. if all goes well, I will have my mailbox set up on my mobile, so then I can get the pics of the previously thought to be TINY track, took pics on tuesday. In time for friday pics.... It is a nice track, with no barriers, just paint and fence, I will try to keep away from it though.
