Product Details

The KSport Version RR Coilover Kit is built for 2012-2018 BMW 3 Series Sedan owners who want a track-ready damper without jumping to a remote reservoir setup. It features a monotube design, high-pressure nitrogen charge, and damping curves tuned for grip — so your 3 Series Sedan stays flat through transitions, turns in harder, and uses its tires instead of fighting them.

Full ride-height adjustment and single-knob damping control give you a usable range from street stance to weekend warrior. If the Kontrol Pro feels a touch soft and you're not ready to step up to two-way, the Version RR lives in the sweet spot — a serious coilover for a BMW 3 Series Sedan that sees real driving without turning into a track-only build.
