R35 GT-R front rotors — 380 × 34 mm, sold as a pair.
Early R35s run a 380 × 34 mm front disc; later cars moved to 390 × 32.7 mm. The diameter went up and the thickness went down, so the two are not interchangeable in either direction — a 390 mm disc will not fit a caliper set up for 380 mm, and a 380 mm disc leaves later pads overhanging.
G3500 high-carbon ring, 34 mm thick against a 32.0 mm minimum, 48.7 mm total height, 68 mm centre bore, 5 bolt holes, 6061-T6 hat with stainless floating hardware. The 380 mm ring has less swept area than the later 390 mm disc, so pad choice matters more on an early car.
Measure diameter and thickness together: 380 mm and 34 mm. The later disc is 390 mm at 32.7 mm, so a disc reading 32.7 mm at the edge is not this part even if the face looks close under a wheel.
R35 front, 380 × 34 mm — OE 40206JF20A. Later cars use the 390 × 32.7 mm pair, OE 40206KB50A and 40206KJ10A.
▸ Fixed or full-floating — which one?
Fixed suits a road GT-R. Full-floating is what most track cars run; the low-speed rattle is expected.
▸ Pads, bedding and ring replacement
On the 380 mm cars the pad sweep is narrower — check pad wear across the face, not just at the outer edge.
▸ Lead time
Built to order. Production takes 10–12 days. Left and right are matched and marked before packing. Transit time depends on destination and service — we confirm shipping and delivery dates by email before you pay.
