KW Coilover Kit Variant 4 (V4) Clubsport 3-Way Adjustable (Non-EDC) – BMW 2 / 3 / 4 Series RWD (F22 / F23 / F30 / F32)

OVERVIEW

Clubsport is KW's track-biased build of the V4 damper. The hardware difference that matters is the top mount: a Clubsport kit ships with hardened race top mounts offering camber and caster adjustment as standard, where the equivalent street kit either has a rubber-isolated mount or none at all. That is what lets you actually run the static camber a track car needs instead of chasing it with control arms.

The V4 Clubsport used here is three-way — low-speed compression, high-speed compression and rebound on separate adjusters — and height adjustable across its full range. The stock damper on these cars is the constraint: factory valving is fixed, factory ride height is fixed, and the OE top mount is designed to isolate noise rather than to locate the strut precisely.

This listing covers KW's F2X/F3X V4 Clubsport, for RWD (2WD) cars only: 3972020D for cars without EDC (Electronic Damper Control) and 3972020E for cars with EDC, across the RWD M235i/M240i, 335i/340i and 435i/440i range built on the N55/B58 platform. It does not fit xDrive cars.

Additional Parts Required

• Neither part number in this listing includes a KW ESC cancellation module. KW does not publish adaptive-damper cancellation hardware for this listing's N55/B58 chassis range; contact us to confirm your car's damper equipment before ordering if unsure.
• A corner-balance and a full four-wheel alignment are required after installation. Clubsport top mounts make camber adjustable, so plan a proper corner-weight and geometry session rather than a quick toe set.

Installation

• Installation instructions (3972020D): PDF.
• Installation instructions (3972020E): PDF.
• Setup manual (3972020D / 3972020E): PDF.
• In brief: full strut-out replacement front and rear, OE top mounts discarded in favor of the Clubsport mounts, ride height set within KW's published range, then corner-balance and alignment.

Notes

• 3972020D is the RWD kit for cars without EDC; 3972020E is the RWD kit for cars with EDC. Neither kit fits xDrive cars.
• Fitment is published by engine family rather than by model year; confirm your car's engine code before ordering.
• Race top mounts transmit more road noise into the cabin than the OE rubber-isolated mounts. This is normal for a Clubsport kit.
• KW publishes no product image for either part number in this listing.
• Price is for the item selected only; labor is not included.
