New shoes and accesories for the C200

I was browsing around Sunway, Glenmarie and Klang area for a set of rims for my C200. I wanted to increase the rim size from 15" to 16 or 17". I saw this Brabus monoblock 18" used originals going for RM2200. Too bad it was already sold, so I am waiting for the next available sets. I also plan to include a LED brake light and projector headlamps for my Merc. Any ideas where I can get them cheaper? Thanks.
