I've wanted to keep the slicers on my daily driven '91 Plus but none of the low budget brake upgrades thus far have really been sufficient to keep up with my "spirited" driving style. I didn't want to shell out $$$ for a set of 17" rims and tires just so I could run cobras with 13" rotors... So.. I took the plunge and slapped on a set of dual piston cobra calipers with 11.6" rotors ('96 and up). This in short required redrilling the caliper brackets to relocate the bolt holes 0.7" further up. End result: WOW. Unbelievable stopping power with less brake pedal effort! Totally blows away the '96 brake upgrade as well as the PBR Mustang GT (non-cobra) calipers on 10.x" rotors that I previously ran. And many thanks to the various fellow SHO fanatics on this forum who took the time to explain how to do this..It really is pretty straightforward.. and a helluva worthwhile upgrade.
