Go with the Wilwood kit for street, IMO. Its low cost, cheap replacement parts and consumables, it is good enough for some track duty, fills the wheel up, and even fits with some 15" wheels if needed. I do not know if you need spacers for stock wheels, but not big ones if any. You can read our experience in our build thread in the signature. But honestly, a set of EBC Blue NDX in front should be enough for street with any useable power level.... again in my experience and opinion.
