Frequently Asked Questions
Refine the handling and stance of your 2003–2008 BMW Z4 E85 with the FIVE8 SS Sport coilover system. Designed specifically for non-M Z4 roadster models, this suspension upgrade allows drivers to lower their vehicle while improving overall chassis balance and road feedback.
The BMW Z4 E85 is known for its lightweight roadster design and engaging rear wheel drive performance. Upgrading to performance coilovers helps enhance the driving experience by reducing body roll and improving stability during cornering.

The mono-tube damper design provides stable damping characteristics while helping manage heat under demanding driving conditions. Electroplated carbon steel shock bodies help protect against corrosion, while CNC-machined aluminum pistons and performance springs support long term suspension reliability.
