Has anyone done this swap? Is it worth it for drag racing? I have one spare floating around and wondering if I should put it into a Willys with a tall gear ratio. I am wondering too how to go about that. The 8/30 combination would give me 3.75, then the smaller diameter tyres (15x11 with PGT-22126 22mm diameter tyre instead of standard 23.5mm diameter) would make the ratio a little steeper. I figure this should get me up into the 40K motor's rev range quicker, right?
Anyone had any experience fitting this 30 tooth crown to a Carrera chassis? Any issues? Is this a silly combination?
