Horse Sense: Not sure if those pie-plate rotors or multi-piston calipers will fit behind your wheels? Check out Baer's Web site at www.baerracing.com for a wide selection of paper templates that correspond to Baer's kit part numbers. Simply print them, cut out the template (use stiff paper or cardboard as a backing, if you wish), and use them to check the fit within your wheels. It's sort of a go/no-go gauge for brakes.

Upgrading your brake system isn't easily done on a tight budget. Depending upon application, kit contents, and options, you might need a second mortgage to get the brakes you want on your Mustang. This is especially true for Fox Mustangs, as most owners opt to upgrade to a five-lug system (requiring new axles), and the front spindles often get the heave-ho for modified or replacement spindles. With all the parts necessary to upgrade Fox brakes, the systems can get pricey.

Fortunately, things have become better since the release of the '94-and-up Mustangs and their factory rear disc brakes. Right from the factory, these Mustangs have better braking systems, and the spindles and rear caliper mounts are upgrade-friendly parts that don't require replacement. This means GT owners can inexpensively swap Cobra 13-inch rotors and calipers onto the front of their cars. Until recently, however, there was little you could do with the rear discs. You could upgrade your GT or V-6 rear discs to the Cobras, but that took used parts or paying out the nose for stock parts from the dealer.

Enter Baer's line of EradiSpeed brake rotors, which has recently grown to include a new series of EradiSpeed +1 rear brake systems. These tricked-out brake-upgrade kits feature EradiSpeed rotor and caliper mounting adapters to substantially increase the rear rotor diameter. In the case of '94-and-later Mustangs, that means an increase from the stock 10.65-inch rotors to whopping 13.250-inch rotors. Not only does the increased rotor diameter improve brake torque and reduce stopping distances, but also the larger rotor fills up the wheel opening nicely, complementing the many cars on the road today with 18-, 19-, or even 20-inch wheels.

The EradiSpeed rotors feature high-friction iron and stronger materials for better heat dissipation, increased friction, and lower wear. Cross-drilled and slotted, the rotors are zinc-washed for protection and aesthetics, and they come with a lifetime guarantee against warpage. One of the best things about these rotors is that they are available in direct-replacement versions for your factory disc applications. They can also be used as upgraded products, such as for the conversion from GT to Cobra front brakes mentioned earlier.

Since our 3g GT has seen about 25,000 miles of editorial abuse and still wears its stock-size rear rotors, we thought the new EradiSpeed +1 package for the rear brakes and a fresh pair of EradiSpeed Cobra-spec rotors up front would get the car looking and stopping even better. After all, you never know when one of those tire treads is going to jump out in front of you-right, Johnson? The swap is so simple, it takes only some hand tools and a couple hours. You don't even have to bleed the brakes.
