Ahh… those are ZCP fronts, which have more conservative width/offset compared to CSL. With 47mm, you’re basically running a 32 after spacer so that fitment sounds right. For an 8” width I think max offset is 30mm. FYI CSL are 8.5 et44 so that’s the 3mm difference we’re talking about.
20 obviously gives you healthy margin but here’s link to 18’s just in case. I don’t think you should mess with the bracket since caliper is centered with rotor. I can’t imagine the width / offset or your bracket is any different than the RR kit I purchased, other than maybe weight.

Yeah, I agree Dubbedown, moving the caliper inward would be an issue when installing pads since the space would not be equal anymore.
So glad you were able to identify these as ZCP rims and that being the difference. I did notice that these rims were 8" and not 8.5" width. Since these are ZCP's and 18mm spacer should still give me tire clearance, right? As opposed to 18mm on a CSL wheel would be pushed out further.
Really appreciate you taking the time to identify the issue Dubbedown! :happyclap: :cheers:
