Sold as a pair — one left, one right, matched. Price is for the pair.
Audi TT RS 8J front rotors — 370 × 32 mm, sold as a pair.
Same 370 mm diameter as the RS3 8V front disc, two millimetres thinner, and a hat that is 10 mm shorter. The RS3 disc is 370 × 34 mm at 59.8 mm height; this one is 370 × 32 mm at 49.8 mm. Fitting the wrong one is a real risk because the diameter matches and nothing else does.
G3500 high-carbon ring at 370 × 32 mm, 30.0 mm minimum, 49.8 mm total height, 65 mm centre bore, 5 bolt holes, 6061-T6 aluminium hat, stainless floating hardware. At 32 mm it sits between the 30 mm and 34 mm discs used elsewhere in the range, which is another reason to measure rather than assume.
370 mm across the face at 32 mm thick, on a 49.8 mm hat. The RS3 8V disc matches the diameter, is 2 mm thicker and sits 10 mm higher — a 2 mm difference you can measure with calipers, and a 10 mm one you can see.
OE reference 8J0615301E / 8J0615301F / 8J0615301K · Minimum thickness 30.0 mm · Bolt holes 5
▸ Fitment check
TT RS 8J front, 370 × 32 mm — OE 8J0615301E, 8J0615301F and 8J0615301K. The RS3 8V disc is 370 × 34 mm at a 59.8 mm hat and will not seat.
▸ Fixed or full-floating — which one?
A lighter car than the RS3, so Fixed is a reasonable default; Full-floating if you track it.
▸ Pads, bedding and ring replacement
Thinner disc, less heat margin — use a pad rated for the temperatures you actually see, and bed in with 6–8 stops.
▸ 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.
