JRZ 12 Series Coilovers BMW M235i / M240i F22/F23 — triple-adjustable motorsport damping built to order in the Netherlands by JRZ Suspension Engineering. Every unit is hand-assembled and dyno-validated before shipping. Browse all JRZ coilovers.
The JRZ 12 Series Coilovers for the 2012-2019 BMW M235i / M240i F22/F23 deliver motorsport-grade triple-adjustable damping with independent high-speed compression, low-speed compression, and rebound control, hand-built by JRZ Suspension Engineering in the Netherlands. Whether you run the N55 M235i or the B58 M240i, the 12 Series gives drivers complete authority over how the F22/F23 behaves on track and street. Also available for this chassis: the 11 Series, RS PRO, RS PRO3, RS ONE, and RS TWO.
The 11 Series handles most drivers beautifully — but some setups demand finer resolution. The 12 Series adds independent high-speed compression adjustment so you can tune transient response separately from steady-state body control. For the M235i/M240i on aggressive track tyres or mixed-use duty, this means dialling out harshness over kerbs without softening corner entry.
Every JRZ 12 Series set is assembled, valved, and dyno-verified by hand at JRZ’s facility in the Netherlands. There is no batch production — each damper is built to order with application-specific valving for the BMW M235i/M240i. Components are machined from aerospace-grade materials and sealed to JRZ’s own tolerances, then tested on a Roehrig dyno before shipping.
This kit fits the 2012-2019 BMW M235i and M240i (F22 coupe / F23 convertible). Compatible with both the N55 (M235i) and B58 (M240i) powertrains. The coilover package includes front and rear dampers with remote reservoirs, vehicle-specific top mounts, and your choice of spring package — Street, Street/Track Hybrid, Track, or Custom rates. Front camber plates are available separately.
