• Pre-set damping calibration matched to the vehicle for balanced road manners and confidence on fast B-roads
• Independent ride-height adjustment to fine-tune stance and the car’s centre of gravity

Lowering range

Vehicle dependent within the tested range. Typical KW V1 adjustment windows are approximately 30 to 70 mm or 50 to 90 mm, delivering a purposeful drop that enhances appearance and handling while retaining real-world usability.

How it drives

The factory-configured damping map reduces squat, dive and body roll without the harshness you might associate with budget setups. Expect a direct, predictable feel with enhanced grip and stability in both dry and wet conditions. A superb fast-road upgrade if you want your Z4 or GR Supra to feel sharper, more composed and more connected to the road.
