Revisited the thread... gonna take my words back about Lumma - seems like the best kit there is for the F15 in terms of looks. Contacted them and... well this definitely requires a lot of thinking
EUR 23.2k for an exterior tuning set with 22" rims (and w/o trunk spoilers) and 24.5k for same with 23". And then you have to pay for painting and installation... The word OUCH comes to mind!
