Spring Rate: Front: 10.0k / Rear: 8.0k / 30 levels adjustable damping
HKS has developed a kit for FL5 that combines the popular HIPERMAX S series with a front pillow upper. It allows for camber adjustment. By increasing the tire size and camber angle, you can prevent understeer.
The three existing MAX IV GT series becomes the HIPERMAX S starting in 2021. 9 years have passed since the launch of MAX IV GT, and during that time HKS has developed new technologies. It will be a new series that has all three conventional models characteristics, and been evolved by damping force characteristics, durability, and beauty. The HIPERMAX S series offers the best ride so far in HKS suspension history.
HIPERMAX S Technical Features:
Front Pillowball Mount
The front upper mount employs the pillow ball spherical bearing. It makes it possible to change the camber angle compared to the existing rubber bearing type of the HIPERMAX S. A direct handling feeling of the car from the pillow ball top mount brings more joy to driving. It reduces unnecessary movement by improving the follow-up performance on the road surface by moving the suspension flexibly. This will provide improved ride comfort on the street.
Dual PVS
We evolved the existing preload valve system to the dual preload valve system to suppress the generation of unnecessary damping force during higher piston speeds. This provides major improvement in ride comfort without affecting the driving performance.
Wide range damping force adjustment mechanism
The improved shape of the Needle jet expands the range of damping force adjustment. This makes is possible to handle driving on a wider range of stages.
Evolution of Bump stop rubber
A new shape of bump stop rubber reduces the body roll and achieves ride comfort at the same time which cannot be achieved with general hydro bump stop rubber.
Low friction technology
With advanced tribology technology, we have achieved even higher durability and lower friction than conventional products. This technology contributes to improved ride quality and handling performance.
3-year warranty from HKS
Compared to the one-year warranty period of the conventional MAX IV GT series, the HIPERMAX S Series has a three-year warranty due to optimized internal parts and quality improvement.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.

Slippery when wet!!!
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
“These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”

Love them
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.
