I was wondering if any member here have upgraded to the 15" or 16" Brembo GranTurismo Brakes. I am thinking of doing that setup next, any opinion on them?

Jim

Look to see that you really get more piston surface over the factory. You could consider larger brake pistons then Brembo.

I would consider this mod myself, the CTT has a some serious weight behind it to stop! Has anyone done this mod?

The stock brakes dont do much on the CS too, unfortunatley the aftermarket parts cost alot.

i think i have the 16 inch, mine are 415mm in the front and 380mm in the back

YEs, you do have the 16 inch up front. Nrembos are a great mopdification if you need the extra stopping power and the amazing looks. Stopping power is immediate and linear with some slight squeeking at slow speeds (normal due to pad compounds). Just remember to upgrade the entire braking system, not just the rotors and pads. Upgrade fluid and such as well. Hope this helps.
