Project Ugly Horse: Part VI

Solid axle? What solid axle?
I was fully prepared to embark on a seven-day journey down a rabbit hole of broken bolts, internet hearsay and consternation.
This should not have gone this easily. Having a long and checkered history of simple projects punctuated by much wailing and gnashing of knuckles, I was fully prepared to embark on a seven-day journey down a rabbit hole of broken bolts, internet hearsay and consternation when I finally decided to lay hands on the '89 Mustang with the goal of relieving the car of its stock rear axle. Instead, it took less than a full morning's worth of work to carve the old 7.5-inch solid axle from its moorings and mock up something, well, different.

Shelby GT350R offers first mass-produced carbon fiber wheels

In the world of race engineering, reducing total weight is good, but reducing unsprung weight is flippin' fantastic. That's the reason Ford is pushing the envelope in terms of technology for the Shelby GT350R's wheels. Joining the likes of Koenigsegg in the offering, Ford has teamed with Australian outfit Carbon Revolution to produce the CF rollers en masse for the first time. Destined for the hubs of the new Shelby GT350R, the new hoops weigh just 18 pounds each, versus the 33-lbs weight of a similar aluminum wheel. On top of slashing up to 60 pounds in unsprung weight, there's such a reduction in rotational inertia – 40 percent, versus aluminum wheels – that Ford actually has to recalibrate the magnetic ride control system and springs. Thanks to, we're guessing, scenes of crashed Formula One cars disintegrating and spewing shards of carbon fiber all over the track, Ford seems quite keen to do away with the idea that CF is strong, but brittle. The company conducted extensive shock testing, ramming a wheel into a curb at speed. According to the Blue Oval, the lightweight wheel allowed the suspension to respond so quickly that the impact was "greatly diminished," causing the tester to run the experiment again, thinking there'd been a mistake. After recording brake rotor temperatures of 900 degrees Celsius (over 1,650 degrees Fahrenheit, or well past the point that aluminum or magnesium would melt) during testing, Ford and Carbon Revolution actually redesigned the wheels to "a thermal standard more suitable for motorsports," by adding an "incredibly thin, nearly diamond-hard coating that reliably shields the resin from heat." The same process was used to protect engine turbine blades on the Space Shuttle. While the work by Ford and Carbon Revolution should make GT350R customers excited, the work being done here could have serious implications for performance cars in the future. That's the real takeaway here, and is something that should leave fans of all performance vehicles excited.

AMC Trans Am Javelin SST, an ultra-rare underdog, is up for auction

Among the rarest of the American muscle cars that went racing in the early Seventies — cars including the Camaro Z/28 and the Boss 302 Mustang — the 1970 AMC Trans Am Javelin SST may be the most hard to find, and among the most valuable. Only 100 units of this unique Javelin were produced, and one of them is up for auction at the Mecum event in Dallas on September 20. The Trans Am Javelin was fashioned in a patriotic livery of tricolor paint — red, white and blue — and arrived after the American Motors Corporation had decided in 1968 to compete in the Trans Am racing series against Ford and General Motors. The company's chief driver, Mark Donohue, would dominate the 1971 season, taking seven wins in his Javelin AMX and that yearÂ’s SCCA Trans-Am Championship. AMC took the trophy with 82 points, well ahead of Ford's 61, Chevrolet's 17 and Pontiac's paltry 7. The example listed for auction came equipped with a 390-cubic-inch V-8 engine with 325 horsepower at 5,000 rpm and 420 pound-feet of torque, power steering and brakes, dual exhaust, BorgWarner four-speed manual transmission and Hurst competition shifter. Its “ram induction system” sealed a chamber around the air filter so that cool air from the functional hood scoop would be funneled into the intake. This JavÂ’s factory price was $3,995 — a mere $32,000 or so in today's money, though it was expensive by the standards of the time. The 100 Trans Ams were among 19,714 Javelin units built in 1970, so they started out rare, and today the surviving examples are highly collectible, if and when they come up for sale.
