I think I saw these rims at Hup Shun and Redzone at Sunway 2 weekends ago. 18' replicas are going for about RM3300 per set. But not sure how much the ori BBS would cost though...
u can get one of those in malacca (Stanford Tyre in malacca raya) saw it yesterday. it cost rm748 a piece (do the math bro..) and also one set of BBS for rm4800.
