KW Clubsport 2-Way Coilovers for BMW M3 E46 (M346) & M3 CSL (06/03+) - Height Adjustable Track/Road Suspension, 16-Click Rebound, 12-Click Compression, Inox-Line

Dual-Adjustable Coilover Suspension Kit for BMW E46 M3 and M3 CSL 06/2003 onwards

Unlock serious pace and precision with this track-focused yet road-usable coilover suspension system for the E46 M3 platform, including the CSL. If you want sharper turn-in, bigger mid-corner grip, stronger traction out of bends and rock-solid stability under braking, this dual-adjustable damper and spring package delivers. Perfect for fast road builds, UK track days and driver coaching cars, it brings motorsport-grade control to the M346 chassis with ride-height tuning and independent damping control.

What makes it stand out

• Independent damping control at both ends: 16-step rebound and 12-step low-speed compression for granular setup
• Ride height adjustment front and rear for stance, balance and aero optimisation
• Inox-Line stainless steel damper bodies for outstanding corrosion resistance in UK weather
• Proven on demanding circuits and built for consistency over long sessions
• High-quality, low-maintenance hardware designed for long-term reliability
• Optional aluminium spherical bearing top mounts on selected applications for even more precision

Who is it for

Drivers chasing a proper handling upgrade on the E46 M3 will love the adjustability and confidence this kit provides. Whether you are competing at club level, chasing PBs on open pit lane days or want a fast road setup that feels planted on B-roads, this coilover system gives you the tuning window to match tyres, alignment, aero and driving style.

How the adjustments help

• Rebound, 16 clicks: refine body control, steering response and high-speed composure
• Compression, 12 clicks: set weight transfer on turn-in and braking, match grip levels and kerb behaviour

The twin adjustable layout lets you run a compliant fast-road setting during the week, then dial in a more aggressive track alignment and damping package for circuits at the weekend.
