JRZ Double Adjustable Coilovers Porsche 996TT 01-05

We are an authorized reseller and installer of JRZ Suspension.  As racing enthusiasts ourselves, we know that the best suspension for street or for track is by JRZ.  With years of engineering, race testing, and winning, JRZ provide the driver with the best possible handling vehicle for their driving needs.

JRZs double adjustment coilover is the ultimate in handling for the track and aggressive street driving.  The double-adjustable shock allows external adjustment of both rebound and compression. In addition to the same precise and accurate rebound adjustment mechanism in the single-adjustable, the double-adjustable shock has a remote reservoir with the compression adjuster and gas volume. This reservoir is connected to the shock with a Teflon-lined high-pressure hose and uses a 22mm piston rod. The double-adjustable allows you to refine the handling of your car by adjusting both the rebound on the shock rod and the compression blow-off valve in the remote reservoir.

The coilovers are sold as as set of 4.  The coilovers do not include springs.  We sell the Eibach ERS springs to be used with the JRZ setup.  We can do custom spring rates based on your driving style.  The spring diameter is 2.25 inch.  The front springs are 7 inches long and the rears are 9 inches.  We recommend for street driving with occasional track days a 400lb front spring and a 500lb rear spring for the Porsche 996TT.  The shocks have 11 clicks of compression and rebound that can be preset from the factory to your driving needs.  The Turbo and C4/s model require front drop links from the Bilstein PSS9 or Agency Power GT3 Front links to work.  The mounting position of the front links is different.  Stock rear links can be retained or you can upgrade to aftermarket ones.  Coilovers do include rear sway bar mounts.  We highly recommend a professional alignment and installation to be done.  Coilovers come from Europe and can take up to 2 weeks to build.

Any questions on this product, suspension setup, or relative Porsche parts, please contact one of our Performance Specialists.

History of JRZ Suspension

JRZ Suspension Engineering was founded in 1994 by Jan Zuijdijk. His mission was to bring a new and revolutionary damper design to the world of motor racing and high-performance sports cars. This new design would aim to eliminate the flaws of old-school hydraulic damper design and incorporate new insights into the complexity of vehicle dynamics and the role dampers play themselves.

J. Zuijdijk worked for Koni on its R&D team, leading him to envision exactly what needed to be modified when it came to the stagnant approach to damping and handling race car suspension. He also had conceived a strong sense of how the prominent role of the hydraulic damper needed to change.  

JRZ Suspension Engineering is based in Uden, Netherlands, and has an office in the United States. JRZ produces racing and custom dampers for any application ranging from motorsports to armored vehicles. Each product is built and tested individually in the Netherlands to ensure only the highest quality possible.
