Im not an industry expert but BC is related to K-Sport, D2, Megan and a few others. Im pretty sure they all source parts from the same set of factories (overseas / Taiwan specifically) - Google it. They are traditionally cheaper but EuroR is correct: usually the quality isnt the best. I noted this in the coilover thread but I wasnt gonna push it on everyone else. If you've had a good experience thats great. Most likely these coilovers will be fine but I'd rather pay for something a bit better. Just my 2 cents.That coilover is total crap. My buddy ran it on his STI, it barely lasted a year. It's half ass engineering. You guys should look into something more reputable.
