Single Tube Damper Design
- Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.
Dust Boot
- Protect the shaft from the flying stones.
PNE Coating
- Using this special surface coating provides 5 times better durability over standard galvanising. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.
M Shaft (?46 normal type)
- With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range by optimizing the oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.
Adopted Pillow Ball Upper Mount
- For more accurate and sharp steering.
New Design Needle
- Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfort ride.
Reduction of Unsprung Weight
- In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminium. (Not for all vehicles)
30 Step Damping Force Adjustment
- 30 levels of dampening adjustment allow fine tune adjustment for street, circuit winding roads, highway, or the weight of the vehicle.

Great for training
Format: Hardcover
I order these for new salespeople and managers who have no construction experience. They think it's a joke until they start going through it.

Perfection!
Format: Paperback
I have read this before digitally, and this is just as beautiful in the physical copy. It arrived in excellent condition. This is my favorite Lovecraft story, and it completely lives up to all expectations. Gorgeous art, moody, faithful to the story, and very detailed.

What adaptations ought to be
Format: Paperback
An amazing adaptation of Lovecraft's classic story to manga that changes only what needs to be changed to make the story work in the new format. The plot is the same, the art is incredibly detailed -- almost too much so -- and the changes in the plot are done only to deal with the vast amount of pure narration in the original. And they're intelligently done. This is how to do it. If you liked the original Shadow over Innsmouth, I think it's safe to say you'll love this.

High quality manga adaptation
Format: Paperback, Format: Paperback
I bought this, along with several of the other paperbacks in this manga series. They are all the same height and width and fit nicely together on my shelf, which is nice.
All of the art is incredible. Some really detailed and haunting images. Most pages are black and white, but there are a few awesome images in color throughout the book.
The quality of the book itself is great, and it's made with solid paper (not too thin).
As someone new to Lovecraft, I really appreciate these versions of his stories which I'm told are true to the original writing.

Best in the series so far
Format: Paperback
I have loved all of the graphic novels of the H.P. Lovecraft stories but this one is by far my favorite. The detail on character expressions nicely compliment the story and is a wonderful interpretation of the source material.
