Specs of RS6 (C6) factory wheels?

Anyone know the details? I'm thinking of getting a set of BBS LMs for my uberwagon, but need to know the offset etc.

BBS offer the LM in 20x8.5 5x112 ET38, would that fit the C6 well?

I just learnt that you should check if the wheels will allow you to check pressure and temperature.
Not even all Audi wheels are good for that. That is if you care about it of course
