My last car run a set of CH's
Comfortably one of the best looking wheels around also for our roads it's very strong too which with pot holes and those with RF tyres is a bonus too.
CHR's are lovely too you won't regret buying them though for many Gen BBS rims price wise can be a tad off putting.
I've seen the Bayern set up on several vehicles don't quite get to me like the BBS setup. But on the E92 have a look at the VHR 710's lovely wheel which really works with the E92 body style IMO and will be cheaper tan the BBS setup by some margin have a look at CMW wheels on here for what they can offer
