BMW 330i Coilover Suspension Kit - Dinan - Dinan Supplemental Ride Quality & Handling Kit - 2012-2018. This listing is for Dinan's supplemental kit, designed to pair with Dinan performance spring sets on F30 320i/328i/330i.

Tuned, progressive-rate bumpstops maximize compression travel on lowered vehicles, helping the chassis use the full spring stroke while reducing sudden bottoming. The result is a more consistent contact patch, improved stability, and composed ride quality without dulling response. Built from OE-quality material and calibrated specifically for Dinan springs, this kit adds predictability and confidence when pushing your BMW.
