The 8Y RS3 runs 374 × 36 mm; the 8V ran 370 × 34 mm. Four millimetres of diameter and two of thickness, and nothing between them is interchangeable — pads, calipers and disc all differ.\u003c\/p\u003e\n\u003cp\u003eG3500 high-carbon ring at 374 × 36 mm, 34.0 mm minimum, 50 mm total height, 65 mm centre bore, 5 bolt holes, 6061-T6 aluminium hat, stainless floating hardware. The 36 mm ring carries more heat capacity than the 34 mm disc it replaces, which is why it survives repeated stops without going blue.\u003c\/p\u003e\n\u003cp\u003e374 is the number to look for, not 370.
