TT RS 8J rear rotors — 310 × 22 mm, sold as a pair.
310 mm, 58.6 mm hat. The RS3 rear disc is 309.9 mm with a 48.5 mm hat — a tenth of a millimetre in diameter and 10 mm in offset. They are different parts and they do not interchange, and the listing photos look the same.
G3500 high-carbon ring, 22 mm thick against a 20.0 mm minimum, 65 mm centre bore, 5 bolt holes, 6061-T6 hat, stainless floating hardware on the fixed variant. 48.5 mm is the RS3 height; this one sits 10 mm taller. At 22 mm there is little material to give up, so measure it before every pad change rather than every other one.
310.0 mm at 58.6 mm hat height. The RS3 rear disc is 309.9 mm at 48.5 mm — the diameter difference is not measurable by hand, the height difference is 10 mm and obvious with a straight edge.
TT RS 8J rear, 310 × 22 mm — OE 8J0615601A. The RS3 rear disc is 309.9 × 22 mm at a 48.5 mm hat and is a different part.
▸ Fixed or full-floating — which one?
Rear, road car: Fixed. Floating hardware at the rear of a light car buys nothing you will feel.
▸ Pads, bedding and ring replacement
Rear discs at 22 mm start thin. Measure at four points; 20.0 mm is the limit and there is no resurfacing margin.
▸ 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.
