Street; Sports Users Get Excited! |Maruha gGreath BC Damper Kit :Pillow Ball Upper Mount Version

Maruha BC Damper Kit, which is a pillow-ball upper mount design, fills comfortable in street drive and a moderate grip on circuits. This product covers all of the MIATA NA and NB series.

1. The kit contents and functions

This kit is a MIATA suspension system that Maruha has developed.
We design or adjust the pillow ball upper mount, the stroke, the body case, the damping force, the gas pressure and so on.

The product contains a pillow upper mount for increasing the stroke, a spring (spring rate: Front 8.0kg/mm, Rear 6.0kg/mm), a damper body and some accessories.

The body case is a single tube shell case that can radiate heat immediately.
It is made of off-black plated drawn steel wire to achieve a low-friction and anti-abrasion feature of a piston.
This piston has 46.0mm diameter that is the largest in the line of the MIATA series and its durability and capacity are in the top quality.

The aluminum pillow ball upper mount is stroked up by being machined specially for this product.
Because the pillow ball made in Japan has excellent quality, you can steer smoothly keeping high durability.

The function of the BC Damper consists of an adjust bracket (overall height adjustment system) and a 15-speed adjustment click shock absorber.

The 15-speed adjustment click shock absorber adjusts damping force at the top of the click shaft and you are able to use it for cross-ridges and circuit drives.
When we show its performance as the spring rates, the shock absorber can withstand until F 12.0kg/mm and R 10.0kg/mm in hard drives, while in street use, F 4.0kg/mm and R 4.0kg/mm (basic rates are F 8.0kg/mm and R 6.0kg/mm).

The adjust bracket, which is an overall height adjustment system placed on the bottom of the damper body, can finely adjust car height, even though there is no spring allowance without helper springs.
This system prevents the springs from excess loads and allowances.
It adjusts from low positions in time attack to street positions.

2. Get more stroke! : upper mount

Our upper mount is designed by ourselves and is made with billet aluminum.
To maintain the stroke rate, the front and rear of the product are machined to the unique shapes.

The MIATA is a lack of stroke and it is the same to any suspension of the car.
In order to solve this problem and to increase the stroke, we improve the shell case length, the rod length, and the upper mount pillow support cc all about the damper kit.

Certainly, the short stroke of the MIATA might be a real headache to you.
While we ease your worry, Maruha BC Damper can also match the needs of many street users who drive the cars in the lowest height on the street.
Consequently, our BC Damper has an enough stroke to make your drive more enjoyable.

3. More durable rod

The rod, including the adjusting shaft and the damping shaft, has the 15-speed adjustment click shock absorber on the top of it.
We make the rod diameter larger to get enough strength.

4. Why the spring rates are F 8.0kg and R 6.0kg?

We feel very sorry for you to find F 8.0kg and R 6.0kg repeatedly.
Now sit around taking a sip of coffee and keep on reading. This guides you to find out the facts on these gmagical numbersh.

If you are an eager reader, it will be clear that gF 8.0kg and R 6.0kghmean the basic spring rates of the BC Damper.
These figures allow you to turn corners while whistling your favorite songs, though the spring is basically for street use.
And the spring rates can work the spring to display its real ability both in comfortable street drive and in severe sports drive by improving the gas pressure and the shim stack.

The features of the spring what you will want in street condition are not only to avoid a rough handling, but also to gain more user friendly steering and strokes.
To meet the requirements, Maruha keeps enough roll for drivers to handle your cars without any troubles.

In a time attack, the low form and the damping adjustment bring fulfilling grip and quick steering.

5. Car height adjustment devices

The spring lower seat, which is made of aluminum, moves about 2.0mm up and down at one revolution.

Once you have got a Maruha BC Damper Kit, our spring lower seat offers you fine opportunities to enrich your car.

The spring lower seat keeps not only the role to avoid the spring allowance but gives you a great chance to arrange the spring preload as freely as you wish by using the adjust bracket together.
Whenever the lower seat and the adjust bracket, so called an overall height adjustment system placed on the bottom of the damper tube, are both used, you can adjust the spring preload without changing your car height.

Moreover, higher spring rates are available through tightening up the lower seat.
You never need to change the spring.
But then, you will find your car height up.?
What can we do for you?
we recommend to lower it with the adjust bracket.

If you make full use of the spring lower seat, more exciting experience of suspension tuning will be anticipated.

6. Bottom bush

Our bottom bush is made of urethane rubber and you do not have to worry about the damage due to the weight on it.
