I must be the only one who doesn't rate the ching chong BC's.... They might work ok for a few thousand k, but they won't last long, they all use low quality materials sourced from the same place, BC, Meister R, HSD, D2 etc, that's why they're 700 quid a set.... I personally know two people who have bought them and had problems, one skyline, one evo, so a 100% failure rate in my eyes... Also, i'd hazard a guess that Tein superstreet use some of the same materials as had first hand experience/problems with them falling apart prematurely. I'd save up for something decent personally, or something with a bit of pedigree, bilsteins etc, as atleast you know they won't fall apart
