Code No. VIITS-SS002
A greedy suspension kit that can drive in any situation even though it is designed for a circuit spec!
A setting for a user who drives at a circuit or wants to drive your car with a quick response. It achieves a cornering speed as never before while maintaining stability.
The model in the photo is 31214T.
■Development Concept
A balance that enhances the driving performance of the VIITS suspension without impairing quality.
- The rigidity supports high-grip radial tires.
- A sense of stability that does not becomes collapse even with quick handling.
- Ride comfort and texture that can be driving on and off the circuit.
- Light feeling that makes driving fun
●Handling Feeling
- Improved steering response
- An overwhelming sense of grounding and lightness
●Performance
- •Although the specification is for a circuit, it has a texture that can be used on the street.
- It has a caster adjustment mechanism as well as a camber adjustment.
●Aesthetic appearance
- Laser marking logo on the top of the upper mount
- Uses exclusive colores for VIITS
■Features of the front suspension
Adopt the 2-way pillow upper mount.
Exclusive design not only camber adjustment but also caster adjustment.
Caster adjustment can be made without removing the damper. Fine alignment adjustment is possible, making the product for those who have a preference.
* It is possible to correct the caster's difference between left and right due to individual differences!
A helper spring is placed on the main spring. It allows for a more precise expansion and contraction of the spring.
Adoption of Low Vibration Spring Balancing handling and ride comfort
Adoption of Super Response Fluid Improved steering response and texture
PVS
Adopts a preload valve system that revolutionizes ride.
It cuts the damping force in the high-speed range and suppresses unnecessary movement.
Newly designed high-rigidity lower bracket with reinforcing plate.
Adopt a special short stabilizer link. Correct the mounting angle at the lowdown.
WR Needle: Wide Range Needle (Damping Force Adjustment Mechanism)
Review the shape of the damping force adjustment needle. The relief passage has been expanded by changing the oil flow rate. The change amount for 30 steps damping force adjustment dial has been widened. Characteristics shifted softer, soft ride setting range widened. The range of tuning has been widened to improve the ride quality in the soft trend when traveling the street.
■Features of the rear suspension.
1
Adoption of PVS and WR needle
Widened range of damper settings
* Please refer to the HKS official website
Improved handling and texture by adopting SRF
2
Adopts a special spring with careful attention to everything from linearity to the number of turns and shapes! We tested approximately six types of springs ranging from 6.8K to 9.9K and adopted the most suitable one at 9.5K. Achieves both pushing-up at low speeds and firm feel at high loads. Achieves flexible movement that does not feel stiff at 9.5 k!
3
We improved the thrust feeling at the rear by developing a dedicated bump rubber to achieve optimal characteristics.
Specially designed for ABARTH595
ADVANCED BUMP RUBBER*
*Dedicated bump rubber (Please refer to the next page)
4
Adopt a special cylinder size. The offset mounting delivered the increased volume of the gas chamber.
■Rear bump rubber: Only for ABARTH 595, ADVANCED BUMP RUBBER
1 OEM bump rubber cut part
It makes it possible to install the bump rubber to the body by utilizing the OEM body mounting attachment parts.
2 Bump rubber holder part
It can be installed with a screw using the hole in the OEM bump rubber as a pilot hole.
3 HKS bump rubber
Rather than shortening the bump rubber to reduce the impact at full compression; by allowing the bump rubber contact, which has a small repulsive force earlier and effect as a sub-spring; changing the bump speed smoothly by increasing the rate according to the stroke amount.
As a result, it makes it possible to reduce the impact at full compression.
