**Color anodized aluminum will change its color lightly over time.
*Please refer to the Sunstar compatibility check page to confirm the size of the stock disc before purchasing.
*Compatibility of brake discs does not guarantee the installation of discs other than the same size (outside diameter and thickness) as the stock discs.
*When changing the outer diameter or thickness, be careful not to interfere with peripheral parts or cause problems.
*Also, when changing from a solid disc to a floating disc, be careful not to interfere with the surrounding parts.
*The design of the inner rotor differs depending on the type of vehicle due to the difference in the installation dimensions (inner diameter) of the wheel.Please note that you cannot choose the design by the same type.

*The inner shape is subject to change due to product specification changes.

■The world's top share of the market, at a lower price.Brake customization starts here■
Sunstar's original stainless steel material is used for disc rotors.
This all-round disc rotor has been chosen by vehicle manufacturers all over the world.
It goes well with stock caliper and stock pad.
A caulk-type floating pin is used for durability and ease of maintenance in street use.
Some of them have the same or better performance than the stock disc sold at the cheaper price than the stock disc.
Please enjoy brake customization more easily.

Tailor the brakes to your liking.
New brake tuning.

[The idea of being able to choose, that's premium racing]

■Selection 1 - Outer Rotor

[control the heat, control the speed, master the braking]
The shape of the outer rotor is the most important part of the brake disc.
How to convert kinetic energy into heat efficiently and how to receive it.
The materials and shapes required for this purpose are constantly evolving.
Two types of outer rotors that can be selected according to use and scene.

■Selection 2 - Plate thickness

[0.5mm dramatically changes the brake feeling]
Little-known disc rotor thickness change.
It is common in the racing world, and the difference in brake feeling by changing the thickness is overwhelming.
Tuning of the plate thickness can be dobe because of Premium Racing.

[Advantages and disadvantages of increasing the thickness of the outer rotor]
Advantages
・As the amount of piston protrusion is reduced, the brake feeling is more direct.
・The increase in thermal capacity makes it more resistant to thermal strain.
・The heat resistance is improved and the lever is stabilized.

Disadvantages
・Some calipers may not be able to be installed.
・The weight will increase.
・The price will increase.

At the latest race site

Disc rotors with a thickness of 6.0 mm or more are used in the highest racing categories such as the Superbike World Championship and the All Japan Championship.
The reason for this is that the performance of suspensions such as tires and suspensions has been improved and the burden on the brakes has become greater.
The thicker the plate, the heavier it is, but the benefits are greater, so this tuning is indispensable for stabilizing the brake touch.

■Selection 3 - Inner Rotor

[Functional virtue tightens feet]
The inner rotor greatly affects the appearance of the brake disc.
The surface treatment is black hard anodized for durability,
Well-crafted inner rotor.
A choice that also affects brake feel.

・S Type (Short Spoke)
Succeeded in increasing rigidity by evolving from conventional spokes.
The simple design matches with vehicles of any age.
Weight 334g (Mounting shape 101)

・M Type (Mesh type)
Excellent in weight M Type.The weight is reduced while maintaining the necessary rigidity.
It is designed to match the latest supersports.
Weight 300g (Mounting shape 101)

・L Type (Lightweight Type)
The L Type is designed with the highest priority on weight reduction.
By reducing the weight of the disc rotor, which is the weight under the spring, the performance of the vehicle is improved.
Weight 150g (Mounting shape 219)

■Selection 4-Floating type

[The future standard for brake tuning, choosing brake feeling]
The floating specification greatly affects the brake feeling.
Full floating specification for improved heat dissipation and a more stable feeling.
Wave washers reduce pin wear, and the semi-floating design makes it easy to use in any driving situation.

・Semi-floating
Because it is tensioned by the wave washer, it is almost immobile.
This reduces the wear of the floating pin and makes it easy to maintain.
In addition, it does not push back the brake pads and can be used anywhere.

・Floating
The outer rotor is not fixed by the clearance without the wave washer, so it is movable.
As a result, the brake pads are in contact with the brake pads for a shorter period of time, which results in superior heat dissipation and improved brake feeling.

■Selection 5 Collar Pin

[make a difference with color, make it unique]
In addition to the standard black color, you can choose from 7 optional colors.
The only disc in the world is now in your hands.
