Hey, I want to build a YRX-12 from the ground up(sort of a project for me) and was wondering if anyone knows the thickness of the stock chassis. I want a car for carpet, and know yokomo offers a 2.1 mm chassis, but if the stock is thicker then I would go for that. Also, does anyone know if Associated sells a complete L4 front end? I thought i remember seeing someone buy a complete front end(all in 1 package)
