Why the JRZ RS ONE for Your M235i / M240i?

Single-adjustable rebound damping — one external adjuster lets you fine-tune body control and weight transfer behaviour without over-complicating your setup process.
Monotube construction — consistent, fade-free damping under sustained hard driving, from spirited canyon roads to full track-day sessions.
Height-adjustable spring perches — set your ride height without compromising suspension travel, maintaining the geometry your chassis was designed around.
Revalveable and rebuildable — JRZ’s open-service design means your dampers evolve with your setup; swap valve shims to match new tires, aero, or power levels.

Not sure which series?
The RS ONE is JRZ’s entry-level damper — single-adjustable rebound with a monotube, remote-reservoir design. Step up to the RS TWO for double-adjustable control, or the RS PRO for a monotube with external reservoir. The 11 Series and 12 Series represent JRZ’s motorsport tier, sitting above the entire RS line.

Hand-Built in the Netherlands

Every JRZ RS ONE damper is assembled by a single technician in Breda, Netherlands. Each unit is dyno-tested against its target force curve and serialized before it leaves the facility. This is not mass production — it is precision manufacturing backed by decades of motorsport R&D at the highest levels of professional racing.

JRZ RS ONE Coilovers — Fitment: BMW M235i / M240i F22/F23 (2012–2019)

This kit is engineered specifically for the BMW M235i (N55) and M240i (B58) on the F22 Coupé and F23 Convertible platform, model years 2012 through 2019. The RS ONE bolts into the factory mounting points with no permanent chassis modifications, and ride height is set through threaded spring perches — preserving full suspension travel at any stance.

Frequently Asked Questions

What is the difference between the RS ONE and RS TWO?

The RS ONE is single-adjustable (rebound only), while the RS TWO is twin-adjustable (compression and rebound). The RS TWO uses a twin-tube design for a different damping character. Choose the RS ONE for simplicity and proven monotube performance; choose the RS TWO if you want independent compression control.

Can I run these on the street?

Yes. The RS ONE is fully street-friendly when set to softer rebound positions. Many owners daily-drive on JRZ coilovers and simply firm up the adjuster for track days — no spring changes required.

Do I need to modify my chassis to install these?

No. The RS ONE bolts directly into the BMW M235i / M240i F22/F23 factory mounting points. No cutting, drilling, or welding is required.

How often should I service JRZ dampers?

JRZ recommends a service interval based on usage — typically every 20,000–30,000 road kilometers or every 30–50 track hours. Service includes fresh oil, new seals, and a dyno re-test to confirm performance.

Can I upgrade from the RS ONE to a multi-adjustable JRZ later?

Yes. JRZ’s modular design philosophy means you can move up to a twin-adjustable or triple-adjustable platform when your needs evolve. Contact Meisterschaft Motorsport to discuss upgrade paths and trade-in options.
