Product Details
The KSport Kontrol Sport Coilover Kit adds a firmer, more track-focused personality to the 2009-2016 BMW Z4. Spring rates and valving run 20-30% stiffer than the Kontrol Pro, giving you the roll control, turn-in, and stability you need when the road opens up or when you start seeing cones. The ride is still streetable, but the priority has shifted toward precision.
Full height adjustment lets you drop your BMW Z4 to a clean, purposeful stance, while independent damping control at every corner gives you a setup that can follow you from the daily drive to the autocross course and back. If you've outgrown entry-level lowering springs and want a real coilover system that rewards a harder-driven Z4, the Kontrol Sport earns its name.
