Dinan Performance Coil Spring Set for 2001-2006 BMW M3 (E46) | D100-0480

The Dinan Performance Coil Spring Set (D100-0480) is precisely calibrated to redefine the handling dynamics of the 2001-2006 BMW M3 (E46). This set provides greater control over body roll through meticulously calculated spring rates, resulting in increased grip and superior confidence in high-speed driving situations. The vehicle is lowered by 5/8" in the front and 1/4" in the rear for optimized suspension geometry and a more aggressive stance. The increase in stiffness actively reduces rear suspension compression under acceleration and front suspension dive under braking, giving the vehicle 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 over the life of the car.

Features:

• Optimized Body Control: Carefully calibrated spring rates provide substantial reduction in body roll, making the steering more responsive to driver input.

• Aggressive Stance & Geometry: Lowers the vehicle by 5/8" (Front) and 1/4" (Rear), improving the car's aesthetic stance and suspension geometry.

• Construction Integrity: Springs are CNC wound, shot peened, and made from high tensile chrome silicon wire to prevent spring sag and ensure lifetime durability.

• Controlled Dynamics: Increased stiffness reduces suspension compression during acceleration and braking (dive), delivering a more predictable and controlled feel.

Product contains:

• (4) Dinan Performance Coil Springs (Front and Rear)

Important Note: For optimal performance and results, use with matching Dinan Koni Struts and Shocks. This kit reuses the factory BMW bump stops and is not compatible with the E46 M3 convertible model.
