Dinan Supplemental Ride Quality & Handling Kit - 2007-2013 BMW 328i/335i | D193-9001

The Dinan Supplemental Ride Quality & Handling Kit (D193-9001) is an essential upgrade for 2007-2013 BMW 328i/335i RWD models, specifically engineered to be paired with Dinan performance spring sets. This additional kit includes tuned, progressive rate bump stops and other supporting hardware that maximize suspension travel on the lowered car for improved handling capabilities and ride quality when compared to just a spring set.

By allowing for full compression travel within the spring, the possibility of a sudden "bottoming out"—a common unwanted side effect when lowering a vehicle—is negated. These bump stops are constructed from OE quality material for progressive characteristics and are carefully tuned for use with Dinan springs, rewarding the driver with added mechanical grip and superior cornering power. This kit is compatible with Dinan Koni rear shocks only (D190-0946).

Features:

• Progressive Rate Tuning: Includes tuned, progressive rate bump stops to maximize suspension travel and prevent harsh bottoming out on lowered vehicles.

• Optimized Mechanical Grip: Bump stops are carefully tuned for use with Dinan springs, optimizing the spring rate for added mechanical grip and cornering power.

• OE Quality Material: Bump stops are constructed from OE quality material for precise and consistent progressive characteristics.

• Ride Quality Improvement: Negates sudden compression impacts, significantly improving ride quality and handling capabilities.

Product Contains:

• (4) Tuned, Progressive Rate Bump Stops

• Other supporting hardware

Important Note: This kit is compatible with Dinan Koni rear shocks only (D190-0946) and is not compatible with xDrive vehicles.
