Great washers for most RC cars. Helps protect paint and stops noise due to body vibration. Use on all my 10th scale RC cars.These are awesome, with these your rc bodies sit a little bit higher (great for extra clearance) but they also stiffen up the shell (it no longer flaps around when picking the car up or when hitting a wall).These are great if your body shell rattles! If not they also protect the paint! Came with enough washers to do 2 x 1:10 Car Shells and have a couple spares.
