Replica CSL style alloy wheels on an E92 M3???

[rash_decision]

Hi, I like the CSL style wheels on the E92 M3 coupe. After looking at one in Lloyd BMW in Carlisle I've decided to get a set. From BMW they are £2019.82 including VAT, but replica sets can be bought for around £550-600. Has anyone fitted a set of the replica wheels to an E90/2 yet? I can't see the justification in BMW charging nearly 4 times the price for a wheel!!
