They bolt on in place of the original discs, work with the factory calipers, and can be run with standard or uprated pads.\u003c\/p\u003e\u003cp\u003eInside, the vanes are directional, so the disc pumps air from the centre out through the friction ring as it turns, which helps it shed heat on fast road drives, autotests and entry-level track days. The discs are cast from a heat-treated CM-250 alloy chosen to cope with repeated heat cycles better than standard iron, and the J-slotted faces help clear pad gas and debris.\u003c\/p\u003e\u003cp\u003eA Geomet coating protects against corrosion through the year. Temperature paint on the disc edge changes colour at set points: green turns white at 478°C, orange turns yellow at 571°C and red turns white at 640°C. If the red mark has turned white all the way round, the discs are running hotter than intended and 034 suggest lower-friction pads, more cooling or their 2-piece discs.\u003c\/p\u003e\u003cp\u003eSupplied as a pair for one axle.
