Going beyond just ride comfort or handling performance, a new standard of "Driving Comfort" aims for comfort in ride but also in the peace of mind generated by handling performance and drivability . An uncompromising balance which delivers on all the demands of street driving.

 

 

The model in the photo is DB82.

 

 

Application

Engine B48
Model Year 19/05 - 
Remarks Toyota Safety Sense may malfunction due to narrowing of the radar/camera beam range and misalignment of the alignment center as the vehicle height is lowered.

*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point

Adopting the latest setting technology, it is possible to experience ride comfort on rough street and vehicle stability while feeling the load shift even in high load range. The stock electrical controlled shock absorber still works well. However, we aimed for a controllable setting in accordance with the driver's intention by using vehicle specific internal valves that makes you easily feel the vehicle attitude.
The test vehicle is equipped with 19-inch high-grip radial tires and boost increased B48 engine. We conducted product test with the vehicle that set up with a perspective vehicle spec of the potential users.
Due to expanding the range of change for one click of the damping force adjustment dial, you can easily adjust the damper force matched with changes in specification of the car such as power up/strengthened brakes/improved tire grip.
The front suspension adopts "inverted" strut type. The cylinder and outer diameter are penetrated into the upright mounting area to secure the necessary stroke volume even at a lowered ride height.
Since it is difficult to adjust camber angle on the lower side of the stock suspension, an adjustable pillow upper is adopted.
The rear is equipped with a special upper plate machined from aluminum, and weight reduction was also taken into consideration after determining the areas where strength is required. Rubber upper mounts are used for riding comfort.
Both the front and rear are equipped with direct-wound springs. Therefore, spring rate can be easily changed.
High durability of 3-year/60,000 km coverage has been achieved by reviewing internal components.
