It may sound strange, but in GT5 I had all kinds of fun making this car literally impossible to drive. Grippy tires in the front, shite in the back, and 200kg of ballast slung over the rear bumper... it was kinda fun putting it in demo mode to see the AI driver try it, only to snap oversteer wildly every time.
But it was through that buffoonery that I figured out that was the way to make a car SUPER stable in reverse... which might not be important, except I tuned my 2J to do 240+mph in reverse (in GT6, it can be tuned even more powerful, and I've gotten it up to 310mph in reverse, with a draft)
