For more information, visit www.P65warnings.ca.gov.The Dinan Performance Coil Spring Set (D100-0902) is an engineered suspension solution for the 2011-2016 BMW 550i (F10), designed to transform vehicle stance while maintaining ride quality and significantly improving mechanical grip. Dinan achieves this by utilizing carefully calibrated spring rates and pairing them with supplemental components (sold separately) to maintain full suspension travel. The set lowers the vehicle by 1/2" in the front and 1/2" in the rear for an aggressive stance and optimized suspension geometry. The increased stiffness actively reduces body roll, rear suspension compression under acceleration, and front suspension dive under braking, giving your car a noticeably more controlled and responsive feel. The springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief, ensuring long-term durability and resistance to spring sag.
Features:
-
Optimized Stance & Geometry: Lowers the vehicle by 1/2" (Front) and 1/2" (Rear), compatible with both conventional and factory electronic shocks.
-
Controlled Dynamics: Increased spring rates provide substantial reduction in body roll, reducing suspension dive and compression for a more controlled feel.
-
Structural Integrity: Springs are CNC wound, shot peened, and made from high tensile chrome silicon wire to prevent spring sag and ensure lifetime durability.
-
Ride Quality Focus: Engineered to maintain suspension travel for a smooth ride while enhancing mechanical grip and handling.
Product Contains:
