This is the strongest model in the world racing scene, famous for its racing model with AP Racing 4 piston brake calipers for the front calipers. The Garland racing rotor is made of the highest quality racing type FCD ductile cast iron, with a choice of rotor diameters of 355mm and 365mm and rotor thickness of 32mm. You can experience brake braking force in another dimension. This price includes a set of dedicated brake pads, stainless steel brake hoses, and brackets specifically designed for each vehicle model.
The floating brake rotor (front only) is fixed to the bell housing (which is fixed to the hub body once the tire is attached) and the disc rotor is not fixed but moves by about 0.2 mm due to the bobbin (floating) on the bell housing. The normal type is fixed and naturally does not move. This movement can cause the judder to escape during braking and make it harder for vibration to occur. Rotors with a slit design are prone to judder, so they may be made to float. This structure was first adopted in Nissan GTRs for motorsport vehicles (GT races) and commercially available cars. The design is specific to each vehicle model, allowing for bolt-on installation.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
