Description

Hyper Racing # 388-454
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. Lightweight CSI Bump Rubber Cup clips directly onto the eyelet of CSI RS-series small body shocks.
