The 390 × 32.7 mm ring on a later R35 has to absorb the braking load of a heavy car that arrives at corners far faster than its weight suggests — and it has to do it lap after lap without going off-round.\u003c\/p\u003e\n\u003cp\u003eThe GT-R has run a two-piece front disc since launch, so this is a like-for-like replacement, not a conversion. What changes is the ring: G3500 high-carbon cast iron at 390 × 32.7 mm, 30.7 mm minimum, 48.7 mm total height, 68 mm centre bore, 5 bolt holes. The hat is 6061-T6 aluminium, joined through stainless floating hardware.\u003c\/p\u003e\n\u003cp\u003eIdentification is a single measurement: 390 mm across the face. The earlier 380 mm disc is visibly 10 mm smaller and runs a different caliper spacing, so the two never share a part number — and never share a pad.\u003c\/p\u003e\n\u003cp\u003eOE reference 40206KB50A \/ 40206KJ10A · Minimum thickness 30.7 mm · Bolt holes 5\u003c\/p\u003e\n\u003cdetails\u003e\n  \u003csummary\u003e▸ \u003cstrong\u003eFitment check\u003c\/strong\u003e\u003c\/summary\u003e\n  \u003cp\u003eR35 front, 390 mm — OE 40206KB50A and 40206KJ10A.
