I'm guessing that the DMC-12 is standard? If it's not I'll pick one up, as I to love this car. Ever since I watched the Back to the Future movies I always have. There is a debate on weather or not a stock DMC-12 would even get up to 88 MPH though.
Can you give an in depth review of whats it does on corner entry, mid corner, corner exit? Does it swap ends while braking or accelerating? Or both? Can it handle both bumpy and smooth tracks? This info will allow us tuners to help you faster, and give you better advice. There are some base line MR tunes floating around out there but I can't find them right now.
