Yeah, I did get fabrun's model, but it's of limited use to me as it was made on an educational version of solidworks (in french too!), and my full version can't edit any of the parts. Gave me some usefull ideas on modelling the nose cone though which was a part I was having trouble with.
Spent the last few days researching Mazda diffs, and i've gone back to the original idea of using the BMW diff, although I will be keeping the mazda suspension. The reasoning behind this is that the mazda diff will only reallistically have a design torque of a couple of lb/ft of torque to give a safty factor on the engine torque, and the Saab engine i'm using can pack out 400lb/ft on only a mild tune, and my aim is to one day rival the Veyron on power to weight ratio... No-ones ever broken a BMW diff to my knowledge.
The other reason is that the mazda diff will only ever be open, viscous or torque sensing. I don't think that i'll ever have the loading to get the temperature up on a visous diff, and i don't like the idea of the sudden leap in torque transmission if it do, and a torque sensing diff is useless if you have one wheel only spinning. The BMW lsd is a true, clutched lsd, with variable locking if you know how to fiddle with them.
