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

Due to the extensive lowering possible and the increased suspension travel, the installer must carefully evaluate tire clearance under all situations. Safety will be compromised if all precautions are not taken. Dinan is not responsible for any property damage or injury.

• Threaded collars allow easy and precise front & rear vehicle height adjustments.
• 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.
• Spring rates are 20% stiffer in front and 15% stiffer in the rear. Stock rear springs are progressive whereas the Dinan springs are linear.
• 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.
• Substantial reduction in body roll.
• Included suspension packers allow adjustment of bump-stop clearance to fine-tune handling and comfort.
• Dinan-spec progressive bump stops improve ride quality at lowered ride heights.
• Components are machined from 6061-T6 aluminum and black anodized for a sporty appearance as well as corrosion protection.
• Stock upper spring mounts are utilized for quiet operation.
