Sustec Z40 uses advanced dampers made by KYB and offers fully adjustable ride height, 40-way dampening adjustment, and a twin tube design. Made and tested on every vehicle application to meet the maximum performance and direct fit.
SUSTEC PRO Z40 uses the same high quality PRO210 Springs found on the SUSTEC PRO FIVE Coilover System.
These are the same springs that were used in the Takata Dome Racing Honda NSX in the JGTC GT500 Class in Japan.
A fully threaded damper lets you adjust the ride height independently without changing the stroke of the damper or preload of the spring. This means you can adjust the height of your car without sacrificing comfort.
40-way Dampening Adjustment
Newly engineered KYB dampers allow for 40-way adjustment. Precisely tune your suspension with each turn for improved handling and feel.
Twin Tube Construction
Twin tube dampers allow for better length compared to monotube systems. This combined with low pressure gas system allows for more control over rough surfaces and comfortable compression.
Nickel plating and black powder coating allows for a durable, long lasting finish that will resist the elements more so than other dampers.
Tapered Locking Nut
With many coilovers on the market, the lock nut is one of the weak points in the design. With vibration, the lock nut can come loose which allows the spring seat to move also. The Z40's specially tapered locknut prevents it from becoming loose from vibrations or harsh driving.
Special resin sheets prevents noises created by the spring shift during compression. Large metallic bearings prevent wear and provides quieter and comfortable ride.
Rigorous Application Testing
Sustec Pro Z40 is carefully designed and tested in every vehicle application. Z40 coilovers are tested to the max by putting them through real world stress, maximum load capacities and the full range of dampening settings and spring rates to give you the best combination of ride quality, durability and the performance you would expect from a Tanabe Suspension Systems.
