Which rear calliper do I need...

[coreythorny]

I've tried searching but not finding much.

Looking online for parts I'm finding various options and sizes from TRW.

I need a new rear drivers side calliper (right).
My car is a 2008 S3 8P (pre facelift).
If cheap enough I may just replace both rears.

Any help or direction is appreciated.

Seems there are a few options. I would take of the calliper , measure the brake disc and piston diameter. Click and collect the possible items and take your old calliper (for the surcharge) to the counter. They'll hand you all the 3 or 4 callipers so you can see which one you need. Then just pay for the right one.

Replaced both my rears in August (one seemed seized and the other didn't look great). They were TRW part number BHN 318 and 317 (right/left). My rear discs are 255mm diam. Bought from GSF and with my 10% discount card about £150 for the pair. Brand new not reconditioned and with a 3-year manufacturer warranty. Identical to the OE ones but the VAG/Audi 4 circles rubbed off. Application label on box says Audi A3 sportback 09/04 - 03/13

Ive just found this post:

Which, line 2, box 5 in my manual states:
1KW J1L 1ZK.

Am I correct in thinking that's the 310mm rears?

I wish I was able to remove it and take it to the counter but I'd need to swap it there and then once removed.

Looks promising?

The BLACKFRIDAY one gives about £55 off.

Would just like someone to confirm they're the correct ones before ordering.
