The Dinan 16-18 BMW 340i Coil Spring Set is a high-performance suspension upgrade designed for the F30 340i (RWD). Crafted with CNC wound high tensile chrome silicon wire and shot-peened for stress relief, these springs offer increased durability and consistent performance. The set provides a full 1-inch drop in both the front and rear, enhancing suspension geometry and delivering a more aggressive stance. With a 25% increase in front stiffness and 34% in the rear, the springs significantly reduce body roll, improve handling, and enhance grip during high-speed driving. This results in a more controlled and responsive driving experience, especially noticeable at speeds as low as 20 mph. The carefully calibrated spring rates help minimize suspension compression under acceleration and braking, offering improved stability and confidence on the road.
Designed specifically for 2016-2018 BMW 340i models with rear-wheel drive, this coil spring set is a direct bolt-on upgrade for the factory suspension. It is ideal for enthusiasts seeking improved handling, a sportier appearance, and better suspension performance for street or spirited driving. The kit includes front and rear springs, providing a complete upgrade to your vehicle’s suspension system. Suitable for daily driving, performance tuning, or track use, these springs enhance the vehicle’s stance and handling characteristics without compromising ride quality. Proper installation ensures optimal performance, making this set a reliable choice for upgrading your BMW 340i’s suspension.
