Front brakes upgraded to Mustang GT ('94-'04) dual piston calipers (PBR), and 300M rotors (stock, 11.7").

They're mounted with an adapter bracket and a hub-centric ring.
The calipers accept the 2G banjo fittings.
17" rims are likely the minimum.

It did not cost much more than $400, all said and done.

These are an obscene improvement over stock DSM brakes.
I could not even imagine the Cobra kit!
