Dinan Ride Quality & Handling Kit - BMW X3 M / X4 M (F97/F98) 2020-2025

The Dinan Ride Quality and Handling Kit adds tuned, progressive-rate bump stops that pair with Dinan performance springs to recover suspension travel lost when a car is lowered. By allowing full compression within the spring, the kit prevents sudden bottoming out and optimizes the effective spring rate for added mechanical grip and cornering power. The four bump stops are made from OE-quality material for a progressive response that improves both handling and ride comfort over a spring set alone.
