Excuse my ignorance, but how can I tell if I have the new tandem master cylinders for the Brembos? My track model was built in October 2003. I am attaching a pic of the brake fluid area if that is worth anything.

 

I don't see two master cylinders there.

 

Nope, single like mine! I'm a little worried about this as well as I want to get a 14" kit for the front and had planned on getting an 03' Track or 03' G35C rear Brembos. I hope that there is no difference in caliper, piston or rotor for the new updated 2 master cylinder models!?!
