Moton Suspension 4-Way Motorsport Pro Coilovers M 500 121 - 1998-2006 BMW 3 Series (E46)

The Moton 4 Way Motorsport Pro adjustable damper system for the 1998-2006 BMW 3 Series (E46) was developed in conjunction with many professional racing teams all over the World. After winning the FIA European Touring Car Championship (ETCC) in 2004 with our Triple adjustable damper, we designed and developed this unique 4-Way damper with Andy Priaulx's Team in preparation of the 2005 FIA World Touring Car Championship (WTCC). The rest is history, and the 2005, 2006 and 2007 FIA WTCC title was clinched by Andy Priaulx running the Moton 4-Way damper system.

Product Information

The Moton 4-Way adjustable Motorsport dampers are available as a McPherson Strut in either Aluminum or Steel or as a Aluminum coilover damper. It can be custom built to your specifications. The Moton 4-Way dampers features separate low and high speed bump and rebound control. The 2 rebound adjusters are located on top of the piston rod and adjust completely independent from each other. Both low and high speed rebound do have a adjustment range of 20 clicks each. The 2 bump adjusters are located on top of the reservoir, the low speed bump can be adjusted into 6 different settings by turning the small knob on top of the reservoir. The high speed bump can be adjusted into 15 different settings by turning the large knob on top of the reservoir.

The 4-Way dampers feature a unique double piston design. The primary large main piston uses a double non-preloaded valve stack for bump and rebound control and is designed for quick response during the smallest movement of the piston. The secondary piston is designed with the use of a unique blow off valve system for high speed rebound control. The low speed rebound is controlled by adjusting an internal needle valve.
