WHY THE RS TWO EXISTS

The JRZ RS TWO puts independent compression and rebound adjustment into a compact twin-tube body — no external reservoir, no remote lines, no extra bracketry. It delivers RS PRO-level damping performance in a package that fits exactly like stock, making it the right choice when you want real adjustability without modifying your wheel wells or running hoses. Built on JRZ’s twin-tube platform, the RS TWO uses the same valve technology found in their motorsport line. Each damper is hand-built in the Netherlands, individually tested, and valved specifically for the Porsche Cayman GT4 and GT4RS 718’s weight distribution and suspension geometry.

• Compression adjustment controls how the damper resists being compressed — tuning body roll rates, dive under braking, and how quickly weight transfers to the loaded tire. More compression gives a flatter, more connected feel in transitions.
• Rebound adjustment controls how the damper extends after compression — critical for traction on corner exit and preventing the chassis from oscillating over surface changes. Proper rebound tuning keeps the tire loaded and the car predictable.
• Twin-tube design means the damper body acts as its own reservoir. No remote canister, no hoses, no custom brackets. The RS TWO drops into the GT4’s factory mounting points with zero modification.

HAND BUILT IN THE NETHERLANDS

Every RS TWO is assembled by JRZ Suspension Engineering in Uden, Netherlands — the same facility and the same technicians that build dampers for professional racing teams. Each unit is individually dyno-tested to verify it matches the target force curves before it ships. This isn’t batch production — it’s one technician, one damper, start to finish. Meisterschaft Motorsport Engineering is the official US importer and distributor for JRZ Suspension. Every kit ships with JRZ topmounts front and rear, and includes expert setup consultation for your Porsche.
