Gas mileage isn’t really affected, in fact we’ve had customers report better gas mileage when going to this gear from a 2.73 or 3.08. The best all around performance gear is the 3.73. The decision between 3.55, 3.73 or 4.10 gears is usually a monumental one for people but shouldn’t be. There are always concerns over gas mileage, street-ability and highway cruising. These pieces should allow us to eliminate the upper control arms that bind whenever the rear axle moves at all and sends wheel rates through the roof.This is one of the most commonly asked questions we get. We’re thinking of augmenting the Steeda setup with a torque arm and Panhard rod from Griggs Racing. The Steeda pieces do a lot to correct some of the shortcomings of the Fox chassis’ inherent design, but we think they may need some help. The Mustang’s rear suspension design is horrid.
The biggest problem now is getting all the torque to the ground. Our 40-70mph acceleration times (in third gear) dropped nearly two seconds.
This change really woke up the car, and increased performance notably.

The other major change we’ve made since the last update is the installation of our Eaton limited-slip and a swap of the stock 2.73:1 rear gear for a set of 3.55:1 gears that we got from Roush Racing (). That’s an unbelievable bargain for that kind of horsepower, and one that we’ll be experiencing personally this summer. Best of all, CCM can sell you a set of new (as in “ BRAND NEW”) GT40P heads, prepped and ready to bolt on, for just over $600. When installed on a Mustang, these heads can give an instant 25- to 35-horsepower boost. CCM’s Dennis Hilliard is a major proponent of the GT40P heads that Ford installed on Explorers and Mountaineers fitted with the 302 V8. Our visit to Central Coast Mustang was eye opening as well. A trip to the dyno should prove interesting with these pieces installed.

We also acquired one of Mac’s Pro Chamber exhaust systems, which they say has all the advantages of an H-pipe and an X-pipe combined.

The folks at Mac produce some cool, and exceptionally reasonably priced power enhancers for Mustangs, and their 70mm throttle body and cold air intake bolted right on with no fuss at all. More research was done out West when we visited Mac Products() in Temecula and Central Coast Mustang () in Tehachapi, Calif.
Now all we have to do is find some tires for them. Eventually we’ll have to go to 17x9-inch wheels if we want to have a real shot at being competitive in Street Modified, but for $215, these eight-inchers are a great place to start sorting things out. Witness the deal we snagged on eBay: a set of 17x8-inch 1995 Mustang GT wheels with worn out R1s for $215. We opted to go for a five-lug conversion since the wheel choices became much larger at that point. Baer claims that the beauty of this system is not only how well it works, but the ease of installation, especially when compared with other brake kits out there. This bolt-on kit is designed to fit inside 16-inch Pony wheels and replaces the pathetic front disc/rear drum (yes, we said “drum”) brake setup with a 12-inch front and rear vented disc arrangement complete with aluminum four-piston calipers and a specific master cylinder. The prettiest of the stuff to arrive has to be Baer’s Sport brake kit () for the Fox Mustang. Although some shiny new toys in boxes have shown up, we don’t quite have all the pieces yet to move to the next phase. Since our visit to Steeda back in January, the Mustang has been mainly a research project while we wait for parts to arrive.
