Buy from them direct.....slikely cheaper then their EBAY auction, and definitely cheaper on shipping (compare to their ebay auctions)
ONLY if you don't mind they send you the wrong stuff or 20 plus days shipping.....customer are 1/2 and 1/2, some said OK and good some said stay away from them....
But apparently they have the most R40 aftermarket stuff for customer in USA and others.
