We have made the newest technology of MAX IV GT for JZA80 for the best driving experience for both comfort and sport.
With the newest technology of MAX IV GT into JZA80 can make the drive fast and comfortable. We have set the goal of MAX IV to have both driving performance and comfort. Therefore HKS has analyzed and test the transient characteristic, not the general pin point so we could develop the suspension that has firmness and still comfortable damping feeling. For this result we have redesigned needle and developed variant port system that greatly improved the damping characteristic of driving feeling at a low speed.
For JZA80, stiff feeling of stock has improved, and luxurious handling by reducing the big behavior change.
It has damping but not so stiff and feel comfortable. It is smooth but does not float and stick to the ground. It fits wide range of driving conditions with one dial setting. And also it can drive from the street to circuit race by changing the dial.

Does not hold as advertised
Color: Black
When the dash got hot from the sun, the glue gave way and everything ended up on the floor. Couldn’t send it back because the time limit had passed but I don’t use it

What a Cute Egg… Err Flower
Easy to install and easy to use! It’s as simple as turning two knobs to tighten onto the screen and placement of the arm. So adorable and has a strong magnet. Looks a little like an egg but who doesn’t love eggs and daisies?

Good mount for tesla cars
Build The design is a very different when compared to regular magnetic mounts. Some people will like it and others wouldn't. This looks like a daisy flower and can be mounted to any tesla car. Material The phone holder itself seems to be made of good materials, and offers a sturdy mount that remains secure in place. It does take some cranking to tighten and there is always a worry of over tighetening and breaking it. Functionality Installation and removal are straightforward and quick. The magnet provides a strong hold for my Samsung Ultra, and keeps it firmly in position during drives. Value for Money (VFM) At $16, the product offers good value, however at a tad higher price. Would recommend only to those who like the looks and need the mounting functionality.
