The original TTRS by default came with '18" x 9J '5-double-spoke' design alloy wheels with 245/40 R18 tyres'

I had these on my RS when I purchased it, however I replaced them with 19" rotors and sold the 18"s.

 

There were also original 8x18" ET52 wheels for winter tyres from Audi. They look similar to the stock 9x18 wheels.

ATS Crosslight 9x19 ET52 do fit. Also ATS GTR 9x19 ET48 were made specifically for the TT RS. I think there are also ATS GTR in 9.5x18 ET52 which do fit. The ones I've seen use them with 265/35 tyres.

Going much lower with offset will likely require some modification to the rear arch liners and / or tab where body joins the bumper.

Hi! Sorry for using your thread, but I'm looking at the same upgrade, anyone knows if these TTS 19 wheels will clear enough for the RS calipers? (Dont want to fit spacers)

Thanks!

 

2Forge wheels have nice brake clearance.
These are TTRS calipers on the 340mm TTS Disc but I did trail fit these onto a friends RS before at the stock 370mm and they cleared fine too..

 

OZ Ultraleggera also clear the brakes in 18"... just!
