I had no idea it was you that started BimmerBoys, bitchin.
As for the bbk, they can be had for reasonably cheap if you take into account the cost of stock replacement parts, and how much a persons stock brakes can be sold for. Mine for example came out costing me nothing. I got brembo calipers with pads and floating rotors for $700, sold my stock brakes for $200, made brackets at work for free (technically I got paid to make the brackets) and the cost of replacing the stock parts and powder coating the stock calipers so they're on par aesthetically with brembos more than outweigh the $500 difference. The only problem thus far is the pads dust like crazy, even OEM pagids aren't this bad.
