I've got bc's and really do rate them build quality wise and design etc for the money.....only issue I have is they only make the one rear spring rate, due to them not being a spring on coilover at the back (someone correct me if I'm wrong though but that was what I was told when I phoned them direct last week)!
If they brought out a set with a proper coilover rear I think they'd be a better product than the Gaz gold's, just a shame they haven't!
