Something Ive always mentioned about coilovers is that very few people have experience of more than 1-2 sets so its difficult to make a fair comparison - on a 200SX for instance Ive used or driven HKS, Apex, Tein, Bilstein, Driftworks, D2 and various ebay specials, as well as KYB, Eibach, Nismo shocks and springs so I feel Im pretty well qualified to make a judgement ....... on a 350 Ive only had HSD's and while they have really impressed me Im not really in a position to say whether they are "better" than BC's or even KW's
