The ultimate street braking system; with naturally anodized lightweight components adapted from our racing program. They use the same STR calipers; AeroRotors(R) and AeroHats(R) as the Trophy Race BBKs; but add silicone dust boots to extend service intervals and anti-rattle rotor mounting hardware for quieter street operation. They also include StopTech(R) Street Performance brake pads for high performance street and occasional track use; and StopTech Stainless Steel Lines. Any StopTech BBK can be ordered as a Trophy Sport Kit by specifying it on the order form. They include forged; lightweight StopTech STR calipers; floating; slotted AeroRotors; stainless steel brake lines; and race engineered caliper brackets. 2003 - 2004 Infiniti G35, 2003 - 2008 Nissan 350Z, 2006 - 2010 Infiniti M35, 2006 - 2010 Infiniti M45, 2012 - 2013 Infiniti M56
