Roger, get yourself to Worksop this Sunday and have a go with my BJ4, I guarantee you will be blown away
Based on my expereince in Florida our tracks arn't actually any higher grip than a well prepared clay track. When the groove started to develop there was more grip than I've ever experienced, certainly enough to get the BJ's front wheels up on hard acceleration. Whats more the locals said the track was only giving '80%' of the grip it could
You just needed to copy the setup I've posted 100% - including the front one-way diff.
If you really throw the car around that much that the rear is folding under with my setup on you want to get yourself an elastic band car (XX4
