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. F90

• Up to 2" of lowering in front and 2-1/8" of lowering in back are possible depending on tire clearance but with diminished ride quality.  Dinan recommends a 1" drop in front and a 1-1/8" drop in the rear to maintain a civilized ride.
• Helper springs are utilized in the front and rear to maintain proper suspension operation under droop conditions as well as accommodate the extensive travel of the stock shocks.
• Spring rates are 20% stiffer in front and 15% stiffer in the rear. Stock rear springs are progressive whereas the Dinan springs are linear.
• Components are machined from 6061-T6 aluminum and black anodized for a sporty appearance as well as corrosion protection.
• Included suspension packers allow adjustment of bump-stop clearance to fine-tune handling and comfort.
• Threaded collars allow easy and precise front & rear vehicle height adjustments.
• Dinan-spec progressive bump stops improve ride quality at lowered ride heights.
• Stock upper spring mounts are utilized for quiet operation.
• Substantial reduction in body roll.

Upgrade the suspension performance and stance of your 2018-2023 BMW M5 F90 with the Dinan D190-0901 Adjustable Coil-Over Suspension System. This kit retains the factory electronic shocks while replacing the original springs with a more aggressive, precisely engineered setup. Threaded collars provide convenient and accurate ride-height adjustment, allowing you to create a lowered appearance while tuning the suspension to your driving preferences. Dinan recommends approximately a 1-inch front drop and a 1-1/8-inch rear drop to preserve a refined, comfortable ride, while greater lowering is possible when tire clearance permits.
The Dinan spring package uses rates that are 20% stiffer in front and 15% stiffer in the rear to reduce body roll and sharpen handling response. Unlike the factory progressive rear springs, the Dinan rear springs use a predictable linear-rate design that supports improved control without sacrificing compliance. Helper springs maintain proper suspension operation during droop conditions and accommodate the extensive travel of the original shocks. Dinan-spec progressive bump stops further improve ride quality at lowered ride heights, while included suspension packers allow you to fine-tune bump-stop clearance for a balance of comfort and handling.
Designed for both performance driving and refined street use, the D190-0901 system includes machined 6061-T6 aluminum components with a black anodized finish for corrosion resistance and a clean appearance. Factory upper spring mounts are retained to help maintain quiet operation. The result is a sleek, adjustable stance with improved suspension control and a substantial reduction in body roll, while preserving the benefits of the BMW M5’s electronic shock system. This suspension system is engineered specifically for the F90 BMW M5 and is suitable for drivers seeking precise height adjustment and more responsive handling.
