I thought I'd run it, see if it would free up, the car ran for 2 mins then lost all drive.
The fault was the circlip in the diff, it had failed and popped out of it's retaining groove.
4 other people at the track had the exact same problem !
Luckily a guy who ran a Couger had anticipated the problem when building his diff, he noted the diff becoming stiff when tightening (as the circlip begins to fail) and he'd replaced his circlip with a Schumacher one.
I rebuilt my diff as did a mate with Schumacher clips and problem solved.
Diff ran ok, but still is nowhere near as free as say an AE diff ?
So beware, your clip could fail in your diff....

I also had the same diff problem at Batley today, however after rebuilding the diff the with the schumacher circlip (thanks Eugene) same happened in the next heat, rebuilt diff again and stretched the circlip slightly and worked ok in the final. And the car was fantastic
