Dinan 21-27 BMW M3/M4 (G80/G82/G83) Adjustable Coil-Over Suspension System

NOTE: 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.
