Hi guys, does anybody know if there is difference between the OEM Brembo and the Brembo GT version BBK(besides the 14" caliper size)? I have a 07 350Z GTC with 12.8" front Brembo and 12.7" rear Brembo. I am thinking of a lighter(and at least as strong as the oem) rotor (and pad...and brake line...and..) upgrade. Is there room for improvement? Is this OEM Brembo enough for occasional auto cross?

Also, with the OEM Brembo, is it just the "caliper" that is actually Brembo? What about the rotor disc, the pad and the brake lines? I don't want to spend $2700 on the GT kit just to find out they are NOT much difference from the OEM Brembo.

Any advise and opinion is greatly appreciated!!!
