considering someone got the TTRS brakes fit on an a3/s3 with 18" wheels I would say yes it will fit on 19"s the RS3 brakes are 370x34mm so you might need a 10-15mm spacer to clear so there isnt any rubbing. You're going to need the whole kit to convert since the existing calipers will not support the larger rotors.

Head vs. heart decisions are especially difficult in automotives. My head should have kept my allroad, which was the most comfortable long hauler I've ever owned. But my heart just had to experience the TTS.

btw: Too bad the S5 transitioned from supercharged to turbocharged in 2017 and hence the "throttle lag."

There are a few 18" wheels that fir the RS3 standard brakes as well. It's the offset to clear the calipers that's the limiting factor, with many 19" wheels having the same problem. The Neuspeed 18" wheels don't require spacers for the RS3. 15mm may not be enough with the rather chunky RS3 calipers and the specific wheel. There's been lots of test fittings of different wheels on the RS3 with most not working.

I have place the rs3 brakes from a 2018 on my 2015 S3. I noticed that the offset of the rotors are off. They seem to closer to the spindle side, so much so that the it rubbed against the metal post under the pad.


What have I done wrong? HAs anyone really put these brakes on a vehicle

In what respect do the S3 brakes fall short? What kind of braking duty do you plan to do with the RS3 brakes if you could in fact make the change?
LOL

After my research I have found that the rotor hat on a mk7/8v model vehicle are 50mm
the rs3 rotor hat is 60mm
also the ttrs 8s model rotor hat is 50mm

so so you would need to purchase the ttrs 8s rotors to correctly fit a mk7 or 8v model
