Brakes
Centric makes all the OEM braking systems for the C34 Stagea, and I've listed their part numbers below. You can sub out to other manufacturers (PowerStop, Raybestos, etc), just compare their part numbers or applications. (I used RockAuto for all the comparisons)
The linked products are ones I recommend, but you're free to choose your own compatible cross reference.
Also noted for the S1, you will need to swap over ALL Q45 Parts, as they're not 100% compatible to interchange, but will fit when you swap everything over.
It's also been recommended to just upgrade to the parts listed for the S2 Rear, and fit them onto your S1 Rear, as the S2 Rear Rotor is a vented setup, and improves stopping distance with better cooling measures.
