Dinan 18-23 BMW M5 (F90) Adjustable Coil-Over Suspension System

Dinan's design retains the superb factory electronic shocks but swaps the springs to a more aggressive formula and implements threaded collars to allow the user to change the ride height. While a stiffer spring is typically associated with diminished ride quality Dinan has also swapped the progressive rate rear springs in favor of a much more predictable linear rate spring design. This allows for a more compliant feel while still being able to enjoy the benefits of a stiffer setup such as the reduction in body roll. The end result is a sleek lowered stance that provides improved handling to go along with its stunning visual appearance. The springs combined with progressive bump stops and other components increase travel that allows the car to be lowered an incredibly low two inches in the front and 2-1/8 inches the rear. However, in order to retain the ride quality synonymous with Dinan suspension kits the recommended drop of 1" in front and 1-18" in the rear is advised. For suspension connoisseurs or those that are just simply very particular suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops something no respectable race car is without.

This upgrade retains the factory electronic shocks while replacing the springs with a more aggressive, linear rate design for improved handling and predictable performance. The adjustable threaded collars enable precise ride height adjustments, allowing you to lower your vehicle up to 2 inches in the front and just over 2 inches in the rear for a sleek, aggressive stance. For optimal comfort and ride quality, Dinan recommends a more conservative drop of approximately 1 inch in the front and 1-1/8 inches in the rear, ensuring a balanced ride that combines lowered aesthetics with everyday usability.

Constructed from durable 6061-T6 aluminum and finished with a black anodized coating, these components are engineered for both strength and corrosion resistance.

Helper springs in both the front and rear maintain proper suspension operation during droop, accommodating the extensive travel of the stock shocks without sacrificing performance. The linear springs, which are 20% stiffer in the front and 15% in the rear compared to stock, significantly reduce body roll, enhancing cornering capabilities for spirited driving.

Designed with a focus on both performance and visual appeal, the system maintains quiet operation by utilizing stock upper spring mounts and incorporates machined components with a sporty appearance.
