[The idea of being able to choose, that's premium racing]
■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.
■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: The thickness of the plate
[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.

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.
■The stock discs of Z900RS are equipped with the stock 300mm diameter discs that are often used in the 250-400cc class. This time, Sunstar introduces the "Φ320 large diameter" which has a powerful appearance like a heavy vehicle and enables severe control with the fingertips.
[Premium Racing] Front Disc Front rotor thickness can be selected from 5.0mm and 5.5mm. ■5.0mm thickness is recommended for city and touring. ■5.5mm thickness is recommended for sports riding on the circuit.
[Sunstar Safety and Security] Sunstar has the world's top-class heat treatment technology, and boasts the latest equipment and skilled production technology. Sunstar's strict standards for materials and products enable us to provide a stable supply of high-quality products for the purpose of "manufacturing safe and comfortable vehicles. All of the stainless steel used in Sunstar's disc series is Sunstar's own special steel for brake discs, which has been developed and produced for use in motorcycle brakes only. It has a specialized performance for motorcycle brakes and cannot be used for other purposes. The brakes are subjected to an optimal heat treatment to achieve superior performance.
This specialized brake steel and heat treatment technology are the most important features of Sunstar discs, and are a major factor in the stable control performance of the brake system.

Caution
*Please note that the product specification may change due to manufacturer reasons. *For the color anodized, please note that it will be discolor with thin color due to aged. *Please check the OEM size on the SUNSTAR corresponding confirmation page before purchasing because there are cases that is different from the OEM disc diameter. *The brake disc correspondence does not guarantee installation other than the same size (outer diameter and plate thickness) as normal. *Please note the interference and peripheral parts when replacing the outer diameter and plate thickness. *In addition, please note the interference with peripheral parts when replacing them from a solid disc to a floating disc. The design of the inner rotor differs depending on the vehicle model due to the difference in the mounting dimensions (inner diameter) to the wheel. Please note that you cannot choose a design of the same type. *Because it is an important security part, please consult a specialized store with expertise and skills and equipment for installation. *Please note that there are cases wherein the inner shape has been replaced due to replacement in the product specification. *This product is sold by 1-piece. Please check the number of vehicles to be installed and purchase. *Please note that the items that can be selected may change depending on the product. *It is different from stock size. It is a bolt-on set that can be increased in diameter with the included caliper offset collar. *It is necessary to adjust the setting to the car body for installation. Please consult with a shop with sufficient knowledge and equipment. *Other types and colors may be included in the image.
