Also if you whould like a cheap R32 setup look for these part numbers:
TRW BDA690 - R32 caliper carrier rear left
TRW BDA691 - R32 caliper carrier rear right
TRW BHS938 - R32 caliper rear left
TRW BHS939 - R32 caliper rear right
I started looking for TRW part numbers after i've seen that my Cupra OEM rear brakes were made by them, so they are the same thing but a lot cheaper.
Zimmerman 100.3309.20 - rotors 310x32mm (not OEM, a cheap quality product as long as u stay away from drilled ones)
You can always go for Caddy calipers, which have the same 41mm pot as the R32 caliper using stock caliper carriers and discs, but the bigger vented R32 rotors will give more cooling.
