Additionally, Dinan lowers the car for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief to last the life of the car. The increase in stiffness will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip for high-speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle.\nG20 \/ G22\nNot compatible with the M440i RWD.\n\u003cul\u003e\n  \u003cli\u003e7-95% increase in spring stiffness in front and 34-92% in the rear depending on stock spring configuration (330i).\u003c\/li\u003e\n  \u003cli\u003eNegligible change in spring stiffness in front and 10% increase in the rear (M340i xDrive).\u003c\/li\u003e\n  \u003cli\u003eNegligible change in spring stiffness in front and 23% increase in the rear (M440i xDrive).\u003c\/li\u003e\n  \u003cli\u003eVehicle lowered 1-1\/8\" in the front and 5\/8\" in the rear (M440i xDrive).\u003c\/li\u003e\n  \u003cli\u003eVehicle lowered 5\/8\" in the front and 3\/4\" in the rear (330i xDrive).\u003c\/li\u003e\n  \u003cli\u003eVehicle lowered 1-1\/8\" in the front and 3\/4\" in the rear (330i RWD).\u003c\/li\u003e\n  \u003cli\u003eCompatible with both conventional and factory electronic shocks.\u003c\/li\u003e\n  \u003cli\u003e15% increase in spring stiffness in front and rear (M340i RWD).\u003c\/li\u003e\n  \u003cli\u003eVehicle lowered 1\" in the front and rear (M340i RWD \u0026amp; xDrive).\u003c\/li\u003e\n  \u003cli\u003eSubstantial reduction in body roll.\u003c\/li\u003e\n  \u003cli\u003ePreset to prevent spring sag.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUpgrade the handling and stance of your BMW with the Dinan D100-0934 Performance Spring Set, engineered for select G20 3 Series and G22 4 Series applications. These performance springs use carefully calibrated rates to reduce body roll, improve steering response, and provide a more controlled feel during acceleration, braking, cornering, and high-speed driving. The lowered ride height also improves suspension geometry while giving the vehicle a more aggressive appearance. This set fits select 2019-2021 BMW 330i and 2020-2021 BMW M340i models, including xDrive configurations, as well as compatible BMW M440i xDrive applications. It is not compatible with the M440i rear-wheel-drive model.\u003cbr\u003eDinan manufactures each spring from high-tensile chrome silicon wire and shot-peens it for stress relief and long-term durability. The springs are preset to help prevent sag and are compatible with both conventional and factory electronic shocks, making them a practical suspension upgrade for street-driven vehicles and performance-focused builds. Depending on the vehicle and original spring configuration, stiffness increases range from 7% to 95% at the front and 10% to 92% at the rear. The M340i rear-wheel-drive configuration receives a 15% stiffness increase at both ends, while the M440i xDrive receives a 23% rear increase.\u003cbr\u003eFeature: CNC-wound high-tensile chrome silicon performance springs\u003cbr\u003eFeature: Shot-peened for stress relief and lasting durability\u003cbr\u003eFeature: Reduces body roll and improves steering response\u003cbr\u003eFeature: Improves control during acceleration and braking\u003cbr\u003eFeature: Compatible with conventional and factory electronic shocks\u003cbr\u003eFeature: Preset to help prevent spring sag\u003cbr\u003eFeature: Lowers the vehicle for improved suspension geometry and a more aggressive stance\u003cbr\u003eFeature: Fits select BMW 330i, M340i, and M440i xDrive models with G20 or G22 chassis\u003cbr\u003eFeature: Not compatible with the BMW M440i rear-wheel-drive model\u003cbr\u003eThe Dinan D100-0934 spring set is designed as a matched suspension upgrade for drivers seeking sharper response, improved grip, and a more composed driving experience without sacrificing compatibility with factory electronic shock systems.
