Overview

Dinan Supplemental Ride Quality & Handling Kit for BMW 230i / M240i / 228i / M235i 2014-2021

Unlock the full potential of your Dinan Performance Spring Set with the Supplemental Ride Quality and Handling Kit. This essential kit includes four precisely tuned, progressive-rate bump stops that restore and maximize suspension travel in a lowered vehicle. By preventing harsh bottoming-out and optimizing the wheel rate, it ensures your springs deliver the perfect balance of enhanced cornering grip and a comfortable, controlled ride.

Key Benefits:

  • Prevents Harsh Bottoming Out: Progressive design absorbs end-stroke impacts, eliminating the jarring contact common in lowered vehicles.

  • Improves Ride Quality: Restores usable suspension travel for a more compliant and comfortable experience over bumps.

  • Enhances Cornering Performance: Optimizes the effective spring rate at the limit of travel, increasing mechanical grip and stability.

  • Spring-Specific Tuning: Meticulously engineered to work in perfect harmony with Dinan Performance Spring Sets.

Detailed Features:

  • Contents: Includes 4 progressive-rate bump stops (Note: Kit quantity is model-specific).

  • Compatibility: Specifically tuned for optimal performance when paired with Dinan Performance Spring Sets.

  • Quality: Manufactured from OE-quality materials for precise, predictable progressive characteristics.

Note: Installation labor time is 6.3 hrs (7.8 hrs on the M235i/M240i) if the supplemental ride quality & handling kit is installed by itself. Installation labor time will be negligible if installed at the same time as the corresponding Dinan Spring Set.
