ST X Coilovers for BMW Z4 E85 & E86 (2003+)

ST X Coilovers Specifications

Drawing on KW's expertise, ST Suspensions kits allow you to easily adjust the height of your car to improve its appearance and handling. Depending on your choice, ST coilovers kits offer a wide range of adjustments and give you the tools to tailor them to your needs.

ST X coilovers are designed primarily for road use. They give the vehicle a personalised look and improve driving dynamics. The ST X is the manufacturer's entry-level range and is ideal for users who want to install a plug & play kit with permanent vehicle-specific setup (ride height adjustment only). They offer an optimum balance between comfort, sportiness and everyday driving pleasure.

The X range is height-adjustable, allowing maximum lowering within the vehicle's technical limits down to 85 mm, depending on the application. ST X coilovers are not adjustable for rebound or compression, and comply with factory-set values.

Boasting outstanding build quality, these coilovers feature galvanised steel struts with an additional coating for superior corrosion protection. They also employ a low-friction, pressure-resistant housing and chrome-plated piston rod for maximum durability, while a one-piece guide and special seal assembly ensure excellent protection against dust and dirt. The polyamide composite adjustment spring seat with stainless steel insert also contributes to the product's high durability.
