Dinan Performance Spring Set for 2018-2025 BMW X3 M40i and X4 M40i (G01/G02)

Fits 2018-2025 BMW X3 M40i (G01) and X4 M40i (G02).

Enhance the handling dynamics and stance of your BMW with the Dinan Performance Spring Set. These springs provide superior control over body roll through carefully calibrated spring rates that improve suspension geometry and provide a more aggressive profile. By lowering the chassis 7/8" (22mm) at both the front and rear, these springs reduce the center of gravity for more responsive steering and increased mechanical grip during high-speed driving.

Manufactured for longevity, Dinan springs are CNC wound from high-tensile chrome silicon wire and shot-peened for stress relief to prevent sagging over the life of the vehicle. This set utilizes linear rate front springs and dual-rate rear springs to specifically counteract rear-end squat during acceleration and front-end dive under heavy braking, resulting in a more composed and confidence-inspiring driving experience.
