Well I checked out the stangnet info then ended up at the Baer site
www.baer.com
Turns out they have quite a number of systems for the 96 up stangs. The one that caught my eye was the 12" front rotor system with the PBR 2 piston calipers. That would fit with the 16" rims and would be a significant upgrade over the stock 11" rotors/calipers. There were some monster systems 13 - 15" with Alcon 4 and 6 piston calipers too
Some models offered rotor/pad upgrades can't remember if they listed the 96 up models.
More food for thought, eh.
P.S. they had up to 15" rotors avail for my Chevelle
Now my gears are turning.
