JRZ 11 SERIES MOTORSPORT DAMPERS
JRZ Suspension Engineering is proud to offer the 11 series; double adjustable motorsport damper. The JRZ 11 series is the embodiment of our damping philosophy, which is to control the unsprung mass. Damping is available over a large range with fine tuning increments. Setup is easy to find and characteristics are fully customizable.
MOTORSPORT DOUBLE ADJUSTABLE DAMPER
Compression and rebound independently adjustable. Rebound adjusted by orifices on the piston rod with check valve so there is no cross talk between the rebound adjustments and compression forces. Compression adjusted by blow off valve in the canister.
COMPRESSION
Control of the unsprung mass is achieved with our blow off valve. The compression adjustment sets the blow of force of the damper, allowing for harshness to be separated from control. Blow off damping settles the car on bumps, curbs, and maximizes grip while transitions and the balance are tuned.
REBOUND
Sprung mass is controlled with rebound damping, delivered smoothly by the 8060 motorsport piston. The 11 series rebound system and 8060 piston provides a linear damping characteristic with smooth pressure development independent of compression forces. This allows the damper to transition between rebound and compression efficiently, maximizing grip and reducing tire wear.
CONTROL OF UNSPRUNG MASS
Control is achieved by using compression damping controlling the movement of the unsprung mass. By doing this the car will take kerb stones or road bumps extremely well and the car will not be unsettled with great control for the driver.
MINIMIZED TIRE WEAR
Using compression damping to control the unsprung mass will result in less tire wear and better tire temps. The unsprung mass will move according the tire’s natural frequency. Using the compression damping the contact patch of the tire to the road will be maximized.
LARGE ADJUSTMENT RANGE
Damping is available over a large adjustment range with fine tuning increments. Set up is easy to find and spring rates can be changed without having to revalve the damper
ADJUSTABLE GAS PRESSURE
The combination of the 22 mm shaft and the use of nitrogen pressure results in a lifting force created by the damper. This lifting force is available through the whole stroke of the damper and works together with the spring, The lifting force is not a spring rate, but gives the car platform.
UPGRADES
There are several upgrades available that increase the dampers performance or tailor the dampers to your needs. In the section below you can find the available upgrades and how they can effect the performance.
