The COX Body Damper for MINI F56 / F66 JCW (Gen 3 and 4) , developed using YAMAHA Performance Damper technology, is designed to improve chassis control, body rigidity, and ride comfort on MINI Cooper S and JCW models. Tuned specifically by AMSECHS, this MINI body damper reduces unwanted vibration and subtle body movement within the monocoque chassis, resulting in a more refined and stable driving experience.
Unlike traditional stiffening parts, the COX Body Damper works by absorbing vibration rather than increasing rigidity, making it an ideal upgrade for daily driving, spirited road use, and long-distance journeys.
Performance Benefits:
Reduced harshness over bumps and uneven road surfaces
Improved stability during lane changes and cornering
Smoother, more refined ride quality
Reduced body vibration and resonance
Improved cabin feel and perceived build quality
Less driver fatigue on longer journeys
(Results may vary depending on driving style and road conditions.)
Key Notes:
Developed specifically for MINI chassis platforms
AMSECHS-tuned settings for balanced road performance
Based on proven YAMAHA Performance Damper technology
Designed for everyday driving and long-distance comfort
