I like it! It still feels like an Audi R8, sensitive steering, good turn-in, a bit loose rear end and very much fun to drive. Your setup keeps the spirit of the car and makes it easier to drive without disturbing the weight balance. The front dips under hard breaking, so it is easy to put it into a slide breaking and turning in. Good when you can set up a sliding turn in, bad if you end up in a sand trap;-)
The gear box is a bit short, so I stretched the final a hundred or so. Very good tune, thanks a lot!
