BMW 435i Dinan Supplemental Ride Quality & Handling Kit (2014–2016). Designed to pair with Dinan performance spring sets, it refines comfort and control on lowered 435i models.

This add-on replaces factory bump stops with tuned, progressive-rate OE-quality pieces that maximize suspension travel and help prevent bottoming. Calibrated for Dinan springs, they allow full compression within the spring, optimizing effective rate for added grip and consistent cornering without extra harshness. Install time: 7.8 hrs (RWD) or 8.2 hrs (xDrive) when installed alone; minimal added time with the matching Dinan Spring Set.

Features

• Includes four carefully tuned bump stops
• Progressive characteristics for controlled compression
• OE-quality materials and precise fit
• Helps reduce bottoming on lowered setups
• Designed for 2014–2016 BMW 435i with Dinan springs
