dont care la, janji rim ringan.....
cos majority taiwan rims are heavy...
google the brand of your rims...so that u know the design, weight etc....
like example advan RG rims, made in taiwan rims got 'made in japan' chop ma,
but its bloody heavy & from far u can c the batang is thicker....
Another way to spot an ori japan rim is to look for a "JAWA"(Japananese Automotive Wheel Assosiation) sticker, most big japan rim companies are "JAWA" approved & usually have this sticker on their rims. (JAWA is like JASMA but for wheel manufacturers).
