Looking to lower your G8X without giving up the factory dampers or adaptive suspension?

Traditional lowering springs give you one predetermined ride height. The KW Height Adjustable Spring Kit gives you the ability to fine-tune the stance while retaining the factory shock absorbers and their electronic controls. This is a great option for those who are looking for that height adjustability without having to go to a full coilover setup.

The KW HAS system combines vehicle-specific lowering springs with threaded height adjusters, allowing continuous ride-height adjustment within KW's tested range.

Adjustable stance.
Factory dampers retained.
OEM+ suspension upgrade.

Why the KW HAS Kit

The KW Height Adjustable Spring Kit bridges the gap between conventional lowering springs and a complete coilover system.

Instead of locking the car into one fixed drop, KW's threaded height adjusters allow the ride height to be individually adjusted even after installation.

The vehicle-specific spring rates are engineered to work with the characteristics of the factory dampers, including BMW's electronically controlled adaptive suspension. This allows you to lower the car while retaining the functionality and characteristics of the OEM damper system.

Lower it to your preference.
Keep the factory electronic suspension.
Designed specifically around the G8X chassis.

Height Adjustment

The KW HAS system provides continuous ride-height adjustment within the following range:

• Front Lowering: 0.6"–1.2" (15–30 mm)
• Rear Lowering: 0.4"–1.0" (10–25 mm)

Unlike a traditional lowering spring, the final ride height can be individually adjusted within this range to dial in the stance and fitment you want.

Factory Adaptive Suspension Compatibility

One of the biggest advantages of the KW HAS system is that it works with the vehicle's original dampers rather than replacing them.

• Factory shock absorbers are retained
• Factory electronic damper controls remain functional
• Compatible with BMW adaptive suspension systems
• Vehicle-specific spring rates are matched to the OEM dampers
• Factory driver assistance and comfort functions remain operational

This makes the KW HAS system an excellent option for owners who want a lower, more aggressive stance without replacing the factory electronic damper system.

Automaz Approved

Not everyone looking to lower a G8X needs or wants a complete coilover system.

The KW HAS kit is a great option for owners who want to eliminate factory wheel gap and fine-tune their stance while retaining the BMW factory dampers and adaptive suspension functionality.

You get the ride-height adjustability normally associated with a coilover system while keeping the factory suspension technology that makes the G8X so capable as both a performance car and a daily driver.
