Dinan D193-3001 Supplemental Ride Quality Handling Kit BMW Jounce Bumper - F30 3-Series

The Dinan D193-3001 Supplemental Ride Quality & Handling Kit is engineered specifically for 2012-2018 BMW 320i, 328i, and 330i models (F30 chassis) to optimize suspension performance when paired with Dinan lowering springs. This precision-tuned kit addresses the increased suspension travel that occurs with lowered ride heights, preventing harsh bottoming and maintaining ride quality.

Key Features:

• Carefully calibrated to work in harmony with Dinan spring rates and lowered ride heights
• Manufactured from OE-quality materials for consistent progressive cushioning characteristics
• Prevents harsh suspension bottoming during aggressive driving or over road irregularities
• Maintains Dinan's signature balance of performance handling and daily drivability
• Direct replacement installation using factory mounting locations

When lowering springs reduce the distance between the chassis and suspension components, the factory bump stops may engage too early or too aggressively, creating harsh impacts. Dinan's supplemental bump stops are engineered with the correct durometer and progressive compression rates to complement their lowering springs, ensuring smooth engagement while protecting suspension components. This kit is an essential upgrade for anyone installing Dinan springs who wants to preserve ride quality without sacrificing the handling benefits of a lowered stance.
