Brakes- semi fronts, ceramic rears

[Weilian]

Looking at getting TRW pads for my '16 A6 - they have a ceramic option for the rear (TPC1547) and only SM for the fronts (TPM1545). Anybody see any issues with running two different brake compounds front vs rear?
Rotors will be Zimmerman's

Why not just choose a ceramic pad that’s available front and rear?

I’m using EBC Redstuff’s all round and very happy.

No squeal.
No dust.
NOT tracked.

I agree with RAF_S7... I have sworn by EBC Red Stuff for years, I just installed them on my S6 in the fronts, the rears the dealer did 5K ago at no charge but I will replace them when needed with EBC Red Stuff and Rotors, as I believe they only have rotors for the rears.
