With the Vintage Venom GT500 front brake conversion, the GT500's 14-inch rotors make our Cobra's factory rear discs look like a Pizza Hut personal pan pizza, even though they're 11.65 inches. My Cobra featured American Muscle's 18 S-style wheels before this swap, but I had to choose new wheels thanks to the different offset from the brake conversion. Vintage Venom specifies a 45mm offset wheel, but when I went looking for wheels, my choices were limited. It was difficult to find a wheel I liked in the needed offset. Vintage Venom's own project car utilizes factory '07-'08 GT500 wheels, but I'm not a big fan of that design. I landed right back at American Muscle and its GT4 wheels. The wheels are an 18x9 Hypercoated design to offer a nice contrast to my white Cobra. American Muscle says an 18x10 GT4 will be available soon, and you better believe my car will have a pair on the back when those are let loose.

Horse Sense: Vintage Venom helps make your wheel shopping easier on its website with a special page featuring wheel designs and offsets aimed at simplifying your wheel selection. A variety of manufacturers are listed to make picking a wheel that much easier.

With the introduction of the '93 Cobra R, we saw a glimmer of hope for our Mustang's braking future-the front brakes featured 13-inch rotors and PBR calipers. Likewise, the rear brake set-up was a disc system, as well. Not since the Mustang SVO had our favorite Pony car had four-wheel disc brakes. Things were looking up.

With the SN-95 Mustang's introduction a year later, every Mustang had four-wheel disc brakes. However, the Mustang Cobra featured the better braking thanks to the same package found on the '93 Cobra R. Cobra brakes have reached legendary status in the Mustang community, and that same basic system stayed in use up through the '04 Cobras, save for the '00 Cobra R, which featured a Brembo front disc brake arrangement with 14-inch rotors.

The latter R-model previewed things to come, as the '07 Shelby GT500 also debuted with a Brembo four-piston caliper setup and 14-inch rotors. If the Brembo setup can make the 4,000-pound Shelby stop on a dime, just think what it could do with a Fox or SN-95 Mustang.

Thankfully, Vintage Venom made that dream a reality with its GT500-to-SN-95 Mustang conversion kit ($395), and we couldn't resist adding those big binders to our in-house SN-95. Ford Racing Performance Parts makes it easy by offering the GT500 gear as '05-'07 Mustang GT 14-inch brake upgrade kit (PN M-2300-S; $1,489).

Part of this conversion entails new wheels since Vintage Venom uses a spacer to provide room for the front calipers. However, Vintage Venom gives you the specs to help you chose a wheel.

Finding a wheel design was difficult thanks to my picky nature; finding a competent shop to perform this swap was easy. I hauled my Cobra over to Real Street Performance in Winter Park, Florida. Jay Meagher and crew made the conversion look easy, and I was in and out in a day, which is hard to believe for any tech article.

Check out the photos and captions to see how I made out.

One thing I've found since installing these brakes is that they produce a lot of brake dust. Regular cleaning is a must, which I don't like, but I do like (a lot) the brake response, which is instantaneous. Scrubbing off speed is effortless. Only the slightest pedal acknowledgement is necessary to slow down my Cobra. I've seen tighter brake and wheel packages, but this one didn't have to self-clearance in order to work. The only drawback to this system is that I find myself tailgating even worse than before since I know I can out-brake the majority of cars on the road thanks to my cat-like reflexes. (Um, OK.-Ed)

Vintage Venom's GT500 front-brake conversion kit includes all the hardware, adapter brackets, and spacers needed to install Shelby GT500 brakes on an SN-95. The adapter brackets are made from moly steel and are black zinc-coated. The front rotor adapters and rear wheel spacers are made from aircraft-grade 6061-T6 billet aluminum, while the kit's wheel studs came straight from ARP. The kits sell for $395 plus $25 shipping and handling.

Here's why we're going through all this trouble. This is Ford Racing Performance Parts' 14-inch brake upgrade kit, part number M-2300-S. This system is also the factory braking system found on '07-'08 Mustang Shelby GT500s. The system's highlights are its massive rotors and Brembo four-piston calipers. The system also includes Goodridge brake hoses. If this system can provide world-class braking power to the almost 2-ton Shelby GT500, just think what it will do for my SN-95 Cobra.

Jay and his Real Street Performance cronies give the thumbs-up once the new Vintage Venom-supplied ARP studs are safely pressed in place. An important part of this step, the ABS exciter rings must be removed so the studs can be pressed into place. If original, these rings are brittle and prone to cracking when you try to remove them. It's a good idea to get new exciter rings, but you must still be careful when installing them.
