Well today was the first of many I hope in the Z3M Roadster. Have been doing trackdays since the late 80's in all sorts of cars, at all different power levels as well but all rear wheel drive and petrol. Today was F'ing cold so could not get tyres up to anywhere near the temp I would have liked them to be. This was the case with both sets I tried. But overall the Z did ok, however lots of room for improvement, so the long path starts to get it the way I want it. Some will be cheap easy fixes other will require lots of £££££££.
