Dinan's Supplemental Ride Quality & Handling Kit adds four tuned, progressive-rate bump stops that work with Dinan performance spring sets to maximize usable suspension travel on a lowered car. The progressive stops keep the suspension from bottoming out harshly at full compression and help optimize the effective spring rate for more mechanical grip and cornering control. They are made from OE-quality material and install as a direct supplement to a Dinan spring set.
