well heres a couple of pics. new car next to the old, new one is a bit longer, thinner and motor and battery a bit further back. weight distribution is much better, the old one needed a lot of weight at the rear to get near to the magic 60/40. also gone back to a pretty much standard b4 front end instead of the tc3 rack. rear end has changed quite a lot, its now more easily adjustable and contains a lot less parts overall, tc3 gearbox instead of b44 brings the spur further back and allows braces to be to the side of the gearbox rather than over.
the old car was quite a safe, easy car to drive, but propably lot that quick overall, exceeded its drivers abilities though..... the new car is a lot more responsive and seems to generate more grip overall, just need a bit of time on track to try and find a good setup, and also to design and make a bodyshell for it.
