OP: I wouldn't waste your money on a BBK for the street. The extra unsprung weight and rotational mass isn't worth it. Instead, you can upgrade the tires and get some nice OEM sized slotted rotors. and good street pads. Throw in some stainless steel lines and nice fluid (ATE Super Blue or Motul fluid are great). Your brakes are only as good as your tires, and a BBK only shows any advantage once things get hot. There's very little chance you're going to be getting your brakes hot enough to need a BBK on the street unless you're an idiot or there's something wrong with your car.
