Ultimate Racing 1/8 offroad insert rubber rings
New from Ultimate Racing are these useful 1/8 offroad insert rubber rings. Manufactured to fit into each of the insert’s grooves, once fitted the insert is practically fixed to the rim. In this way, the insert is prevented from moving laterally, improving stability in fast corners. It also prevents the insert from ballooning making the car much more stable under acceleration. They can be used on most inserts, wheel brands and compounds, but their effects are greatest on soft compound tires. Depending on whether you want the insert to be more or less fixed, they can be used in all three grooves, in two or only in one. They are sold in bags of 50 pieces so that you can assemble from 4 to 12 complete cars depending on the amount of rubber bands used per insert. Once the life of the tire is over, they can be reused as many times as you want.
