Dinan Ride Quality & Handling Kit - BMW G20 330i / M340i / G22 M440i xDrive

Lowering a BMW with a spring set without addressing the bump stops creates a predictable problem: the shortened suspension travel causes stock bump stops to engage too early, leading to sudden bottoming out and degraded ride quality. Dinan's Ride Quality & Handling Kit solves this with progressive-rate bump stops tuned specifically for Dinan springs on the BMW G20 330i, M340i, and G22 M440i xDrive platforms.

By maximizing available suspension travel at the lowered ride height, the kit eliminates the abrupt bottoming out that compromises both comfort and handling. The progressive bump stops also add a rate effect through corners that improves mechanical grip — a genuine performance benefit alongside the comfort improvement. Set of 4 bump stops. Required companion to get full performance and ride quality from Dinan spring sets on this platform.
