i recently came across a pair of front sports 350z 2 piston brake calipers w/ rotors and hawk pads for $200 w/ about 700 miles on the pads...not sure about the calipers or rotors. How much of a difference is it compared to the 04 non-brembos? I was thinking of powdercoating them, buying steel-braided lines and aftermarket cross-drilled rotors to have better braking and better looks...would i need to run any spacers to make my wheels work? i have a 20x9.5 w/ +7 offset up front..any insights on this?
