Hey Jersey, I'm also looking forward to getting my hands on the M8/upgrade parts...
I'm very happy with the way my Turbo is handling at the moment. It still steps out from time to time, but i am running it stock except for diff and shock oils.
I've had almost no breakages (stock wing doesn't take much punishment), but the thing that annoys me is that i keep loosing king pin screws and the bushes which you cant buy seperately
Other than that, i am very happy with the car and only hope i can improve it further!
