Hyper Racing # 389-425
Requires Snap Ring 389-510.
The purpose of a bump rubber cup is to keep the bump rubber from expanding and deforming. When the bump rubber cannot expand, its effective spring rate is progressively increased. Use this bump rubber cup on the left rear for wingless racing to tighten the car on exit. Proper timing is important.
