BMW 230i Coilover Suspension Kit - Dinan - Supplemental Ride Quality & Handling Kit - 2017–2021. Built to partner with Dinan performance spring sets, this kit refines ride quality and sharpens handling on your lowered 230i.

This supplemental kit replaces the factory bump stops with carefully tuned, progressive-rate units made from OE-quality material. By maximizing usable suspension travel, it reduces harsh bottoming and keeps the chassis composed, allowing the springs to work through their full range. The result is more consistent grip and confidence without giving up daily comfort. Estimated install time is about 6.3 hours when installed alone; labor is negligible when paired with the matching Dinan Spring Set.
