A 1/10 pan car is 190mm or 200mm, not 235 (thats gas).
I think a 19t motor (Now that Roar was kind enough to make them legal, lol), any type of body and 4 cells would be the way to go, IMO. Or at least thats what normally run on carpet... in the North-East.
As far as bodies, normally we run the protoform 911-GT1 body, however I think that gas Lola bodies would fit, and it would be cool to see different bodies.
Handout foam tires arent really nessesssary, IMO.
