MSS 19-21 BMW X4M / X4M Competition / X3M / X3M Competition Urban Full Adjustable Kit

A versatile performance spring kit developed for dual purpose duty. This kit is ideal for vehicles used daily, spirited drives, or on race tracks to serve all driver skills up to an advance level.

Fits vehicles with Active and Non-Active dampers.

The triple rated rear kit coupled with the single rated front spring kit offers the following proven additional benefits over the factory (OEM) setup:

• Reduced rear squatting under acceleration - especially beneficial at corner exit;
• Reduced dive and skate on hard braking.
• Retains the in-dash ‘One-touch’ operation to change suspension from soft to firm mode settings.
• Improved ride comfort over rough tarmac and road bumps.
• Balanced and composed handling on roads or race track in the wet or dry, comparative to a premium passive Coilover kit.
• Get to use advanced suspension setup features found in premium passive Coilover kits such as rake or corner balanced / cross-weight.
• Modular design with easy upgrade path from MSS Urban > MSS Sports > MSS Track requiring just a change of a single spring on each rear corner ONLY.
• Upgrade from one kit to another - thus MSS Urban to MSS Sports or to MSS Track - in less than 30-mins (excludes re-alignment).

Front axle adjustable ride height range is from factory ride height (0mm) up to -30mm (+/- 3mm tolerance). Rear axle adjustable ride height range is from factory ride height (0mm) up to -30mm (+/- 3mm tolerance).
