After uninstalling the stock suspensions, the warning lights on your dashboard will turn on. Please install the 「SUSPENSION WARNING CANCELLER」 included in the kit. ※The Canceller will only turn off the warning lights. The error signal inside the Stock Adaptive Damper System will not be completely eliminated. By installing the Canceller, vehicle diagnostic may become unavailable

Notes - With canceller. Can be installed on vehicles with variable damper system.
Variable damper system cannot be used. Rear damping dial is inside the wheelhouse.

Height-adjustable suspension kit DAMPER ZZ-R

• A full-length adjustable suspension kit with a monotube structure.
• This fully adjustable suspension kit is reasonably priced.
• The 32-stage damping force adjustment mechanism allows for a wide range of damping force adjustment, making it suitable for all driving situations, from the street to the circuit.
• The upper mount, lock seat, and some brackets are made of aluminum, achieving both high strength and light weight.
• The monotube type uses a large diameter piston of φ44 to suppress the delay in damping force.
  This provides a smooth ride and reliable tracking (excluding some models).
• We support pre-delivery overhaul of cartridges, allowing for smooth replacement of consumables unlike anything we've seen before.
• 
  It has been given the title of Hall of Fame in the "Parts of the Year" awards run by the car social networking site "Minkara" as a product that has garnered unwavering support .
• Click here for details on the electronically controlled model "SpecDSC PLUS," which allows damping force adjustment using a controller from inside the vehicle .

"Full length adjustment type" and its advantages

What is full-length adjustment?

The "screw type" that has been adopted mainly for affordable coilovers by simplifying the structure requires adjustments such as loosening the spring or applying preload (shortening) when adjusting the ride height.
These adjustment methods tend to cause problems such as a worsening ride comfort, bottoming out, and abnormal noise.
The "full length adjustment type" adopted by DAMPER ZZ-R allows the entire length of the shock absorber to be adjusted independently of the spring.
This allows the ride height to be adjusted without changing the stroke amount, so there is no need to worry about bottoming out or other problems.

Of course, just like the conventional screw-type, it is possible to adjust the vehicle height and preload by expanding and contracting the spring, allowing you to use it further to suit the situation.

Full-length adjustable structure and benefits

The vehicle height adjustment of the full-length adjustable type is done by raising or lowering the lock position (B) of the lower bracket.
When the position of B is raised, the overall length (full length) of the shock absorber becomes shorter, so the vehicle height is lowered by that amount.
With the full-length adjustable type, the length of the spring (A) does not change at all even when the vehicle height is lowered.
In other words, the stroke amount (range of movement) does not change, so it is possible to achieve a lowered vehicle while keeping changes in ride comfort to a minimum.

"Single-cylinder type" and its advantages

What is a single-cylinder type?

"Monotube" refers to a type in which the inside of the shock absorber shell case becomes a cylinder, and oil, gas, piston valve, etc. are contained in a single tube. It is characterized by the fact that the oil chamber and gas chamber are completely separated by a free piston.
"Twin-tube" is a structure in which there is another cylinder inside the shell case, and a piston valve moves up and down inside it.
DAMPER ZZ-R uses the monotube type in all lineups, aiming for a stable damping force generation by a simple structure, high rigidity, and a larger piston diameter.

Single-cylinder structure

• It has a simple structure, is highly rigid, has excellent heat dissipation properties, and is highly durable.
• It has a large oil capacity and ample thermal capacity, allowing it to provide stable damping force.
• By making the piston larger, more precise damping force adjustment is possible.
• Since the oil chamber and gas chamber are completely separated, there is a high degree of freedom in installation.

Double tube type

• Because the structure is complex, heat tends to build up and manufacturing costs are high.
• Due to its construction, the oil capacity is reduced.
• Due to its structure, it is difficult to increase the diameter of the piston.
• Since there is no separation between the oil chamber and the gas chamber, there are restrictions on the mounting angle.
