Zebra: BC's are a bit of a far-right entrant, I had the same impression when I saw them - cheap china special coilovers. However, they have scored some good reviews so I thought I would do some more research. My budget is 3.5k and id prefer to spend under that if possible, so if these could get reasonable performance at less of a cost then it was worth considering, as this would leave some money in reserve for other components such as a bushs and some LCA's for the rear.
slowmedown: Thanks, I have read through that thread as well. Some good discussion but still no hard facts in there as to their performance on the track apart from some vague reviews saying they were "good", more focused again on the street. I have a set-up similar to yours (whiteline adj. swaybars, cusco upper arms, JJR castor rods, tein super streets, 430 hp) and I was interested in comparing track times at lakeside.
Ultimately however I don't think anyone is going to be able to give me a definitive answer on these, it would seem I just have to try them and see, which may result in me going the 2k (on special atm) for the monoflex's instead as I know they are decent.
Thanks so far for the input however.
