Can anyone comment on the pedal feel of this kit?

Any other relevant information surrounding this kit would also be great!

Pedal feel should be near identical to the OEM RS setup. The total piston area is about 4% more when compared to the RS4/RS5/R8 caliper (2956mm vs 2840mm)

I love the aesthetics of the 19Z caliper and think it looks better than the RS5 caliper. Beyond that, this kit and the OEM RS5 setup (when paired with 380mm rotors) should give essentially the same performance. I'd go with whichever you can get a better deal on!

Also, FWIW, ECS offers their own version of this kit with a slight difference in that their rotors are 38mm thick versus 34mm thick for the JHM kit. The JHM kit is priced a bit better and their kit includes pads while ECS' kit does not.

damn, 380x38 (https://www.ecstuning.com/Audi-B8_S4-Quattro-3.0T/Braking/Performance/Front/Stage_4/ES2825794/), now that's a heat sink.

But the RS has a different master cylinder, correct?

FWIW - if you care about brake balance and overall performance, I asked stoptech their thoughts of a system with 380mm rotors and the piston area of the 19z, didn't tell them it was the 19z, but... Their quote was something that included the words "grossly oversized" for proper brake balance on the B8/8.5 platform.
