[The idea of choice, that's PremiumRACING]

Selection 1 -Outer Rotor

[controls heat, controls speed, masters braking]
The shape of Outer Rotor is the most important part for Brake Disc..
How to efficiently convert and receive kinetic Energy into heat.
In order to achieve this, the necessary materials and shapes are evolving day by day.
Two types of Outer Rotor to choose from depending on the application and scene.


Selection 2 - Thickness

[0.5mm dramatically changes the Brake Fee Ring]
Changing the thickness of the lesser-known Disc Rotor.
It is common in the race world, and the difference in Brake Fee Ring by changing the thickness is overwhelming..
PremiumRACING makes it possible for you to have thicker tunings.

[Merit and Demerit by increasing the thickness of the Outer Rotor]
"Merit.
The directness of the Brake Fee Ring is increased because the amount of Piston protrusion is reduced..
Increasing the heat capacity makes it more resistant to thermal strain..
Heat resistance is increased and level is stabilized..

"Demerit.
Depending on the Caliper, it may not be possible to install it..
Increase in weight.
Price will go up..

-Reference value-
Part number:DE10 5.0mm thickness 320mm weight 1290g
Part number:DE12 5.5mm thick 320mm weight 1485g

On the latest race scene...

Disc Rotors with a thickness of more than 6.0mm are used in the premier race categories such as SUPER BIKE World Championship and All Japan Championship..
Behind this, the performance of undercarriage components such as Tire and Suspension has been improved and the burden on Brake has become larger..
The thicker the board, the heavier it is, but the larger the merit of the thicker it is, the more stable the BrakeTouch is and the more tuned it is to the stability of the BrakeTouch..

Weight 150g (fitting type 219)


Selection 4-Floating type

[The future Standard of BrakeTuning, choosing the Brake Fee Ring]
Spec of Floating that affects the Large in Brake Fee Ring..
Full floating spec for improved heat dissipation and more stable fee-ringing..
The wave washer reduces pin wear and allows for a semi-floating spec for any driving scene...

・semiFloating
It is almost immobile because of the tension caused by the wave washer..
This reduces wear on the floater and provides excellent maintenance..
Also, there is no pushing back on Brake Pads and no need to run anywhere.

・Floating
Because the Outer Rotor is not fixed due to the clearance of the absence of the wave washer, it can be moved..
As a result, the time in contact with the Brake Pads is short, and the heat dissipation is excellent and the Brake Fee Ring is improved..
