Balancing high speed stability and comfort for city driving

The G8X generation M has electrically adjustable dampers as stock, and while they provide the stability typical characteristics of the M series at high speeds, they still are a bit stiff in daily driving, even in “COMFORT” mode. The HKSTUDIE SUSPENSION was developed based on the concept of “Balancing high speed stability and comfort for city driving”.

High rigidity inverted dampers are used

The mono-tube dampers are equipped, which enables the use of a large-diameter piston and provides high-quality and stable damping force. In addition, high rigidity inverted dampers are used for the front suspension, as the strut type suspension system is subject to heavy bending loads during acceleration, deceleration and cornering. This leads to excellent handling.

Fully-threaded shock body

Fully-threaded shock body is adopted for both front and rear, allowing adjustment to the desired ride height without affecting ride comfort by changing the amount of damper retraction stroke or spring pre-load. Wheel gap between the front tire and fender is noticeably big with the stock ride height, so we set the front end slightly lower relative to the rear to obtain a more stylish appearance and improve high-speed driving stability.

The 30-level damping force adjustment

The 30-level damping force adjustment allows the driver to set the preferred damping force to suit various driving conditions, from city driving to the race track. You will experience the evolved “The Ultimate Driving Machine” by having balanced performance of smooth ride on the street and a steady driving feel at high speed, perfect for the M series.

Features the camber-adjustable top hat

The front unit features the camber-adjustable spherical-bearing top hats for sharp handling. CNC machined aluminum top hats are adopted for the rear unit.

Suspension Error Canceller

“Suspension Error Canceller” is included in the kit to delete the error light upon removal of the electrically adjustable damper.

3-year/60,000 km product warranty

By manufacturing in-house at our factory in Japan and conducting thorough quality control, we are able to offer a 3-year/60,000 km product warranty coverage from the time of purchase. We also offer overhaul and customization services after use. In addition, we can change the spring rate of the front springs for free at the time of product order.

Characteristics of Piston Valve

As a general characteristic of piston valves, damping force is less effective at low piston speeds and increases at higher speeds. The Dual PVS (=The dual preload valve system) used in this product improves damping force at low speeds and suppresses it at high speeds. This results in less thrust and bouncing, and improves tire traction.

 Advanced Bump Rubber

Characteristics of Bump Stop Rubber

Typical bump stop rubbers are intended to stop the stroke when the suspension bottoms out, but produce a strong impact as well. The advanced bump rubber used in this product is soft and long in shape, allowing the bump rubber to function as a sub-spring by making the bump stop contact earlier. The result is not only a lessening of the impact at bottoms out, but also an increase the overall spring rate at every strokes.
