Big thank you to Bara and Dennis.
Ran the car last weekend at a race circuit here in Germany, Schleiz dreieck.
The car performed very well with new parts. No problems and although I'm no profi, I'd say the car was very good through the corners.
Bara supplied,
front plated 6 1/2" diff.
Rear 7 1/2" 4.44:1. 240Nm VC.
Big tooth gearkit, 4.44 step down gears. 60Nm VC.
D Osbourne supplied the 7 1/2" rear beam. Now the rear wheels can be set up properly. I could write down the set up if anyones interested. (in the other forum if required)
Thanks guys.
kenny.
