I wish people would stop calling BBS RXIIs split rims - they are not.
They are 2 piece.
The rim is NOT split like on an BBS RS, the rim is one piece, the centre another.
I've re-furbed 6 sets of RXIIs in the past (still own 4 sets of 7" wide Anni RXIIs) and they can cost you £350-400 to refurb properly yourself...so paying £500-600 for a good, straight, properly re-furbed set is a pretty good price.
Anything less is a bargain in my eyes.
