PSG, I haven't used the car yet, but I think the reg stratos chassis would work. Go into stats and chech wheelbase, then get to the program and try to find a matching one, but make sure it doesn't match the Rally Stratos chassis(meaning the stats in the game read the wrong wheelbase). I did it on the Miata '89 Opt, and used the Elise chassis. If it is reading the wrong wheelbase, and the wheels need to be moved farther away, get a chassis that's a little bit bigger, and make sure it's MR and the right wieght(or close to it). It's sorta trial and error, or trial and good.
