RPM has a few new products for the SC10 2WD. They have a new Rear Bumper which is wider than the stock bumpers giving a little more protection. The top has also been raised to help protect in case of a crash. The rear bumper also has mounting points for the RPM tail light set, mud flaps and number plate. The bumper will run you about $10, and the mud flap and number plate kit about $11.
