What makes KW V3 stand out

• Two-way damping control for ultimate tuning freedom. 16-stage rebound and 12-stage compression let you fine tune body control, steering response and road compliance.
• Ride height adjustment for a tailored stance and centre of gravity. Achieve the look and performance you want while keeping drivability.
• Stainless steel damper bodies with Inox-Line corrosion protection for long-term durability in UK weather.
• Trapezoidal thread with composite spring perches to resist seizure and make height changes easy season after season.
• Developed on KW’s 7-post rig and proven on the Nurburgring. Real-world performance with road comfort.
• Sharper turn in, stronger traction and reduced roll, squat and dive without ruining ride quality.
