Many Skyline owners use this system on the street, though you should expect a firmer pedal and quicker engagement point than stock. It is best suited for track-focused or high-powered builds.\u003c\/p\u003e\u003cstrong\u003eDoes the CLM06045PTD80S meet SFI certification requirements?\u003c\/strong\u003e\u003cp\u003eYes.
