Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.

DP Motorsport tries to turn a vintage Porsche 911 into a sleeper

Once you get past the fact that it's hard to call a car a sleeper when it has race-product stickers on its quarter panel, and the script across the back panel reads "Porsche 911 3.2 Sleeper," it's fun to imagine what this car can do. Celebrating the 50th anniversary of the Porsche 911, Germany's DP Motorsport took a model from 1986, stripped it of everything - including the paint and undercoating - then replaced everything with lightweight and race-ready parts.
In went race cams and ported cylinder heads, a lightweight flywheel, an RSR titanium racing exhaust, 935-style lollipop seats and RSR carpeting, a lightweight battery, perforated and galvanized hinges and brackets, hardened perspex windows. The 3.2-liter engine puts out 270 horsepower - 70 hp above the stock 911 on sale here in 1986 - and 226 pound-feet of torque through a limited slip differential to staggered wheels. The exterior color is metallic rock-green lacquer.
If you want one, $120,00 is where the part starts, but DP Motorsport says it offers the parts individually if you don't need your vintage Porsche to sleep this hard. On a side note, for a chucklesome journey back in time, check out this review of the 1986 911 that gets things going with this line: "First off, the Porsche 911 is very expensive - how does about 40 thou grab you?" Back on topic, there's a press release below that tells the rest of the story of the 3.2 Sleeper.

Ruf Turbo Florio is the Turbo Targa Porsche won't sell you

Porsche offers a staggering array of 911 variants. You can get the Carrera, Carrera S, Carrera GTS, Carrera 4, Carrera 4S, Carrera 4 GTS and Turbo and Turbo S (to say nothing of the GT3 and new GT3 RS). And with few exceptions, you can get each as a coupe, cabrio or Targa. Except you can't get a Turbo Targa. The partial-convertible model tops out at the GTS. But if the one thing you really wanted was a Targa with a turbo engine, the folks over at Ruf will be glad to hook you up with the tuned version you see here. It's called the Ruf Turbo Florio, taking the latter part of its handle from the second part of the Sicilian road race where Porsche got the name for its lift-top in the first place. But Ruf's take doesn't just match the factory Turbo's output – it far exceeds it: with 621 horsepower and 608 pound-feet of torque on tap, it'll put even the 911 Turbo S (on Sport Plus overboost, no less) to shame. Plus you can get it with a six-speed manual or seven-speed DCT, driving all four wheels like the factory Turbo or just the rear set like the GT2 that Porsche doesn't even make any more. It'll top out at 205 miles per hour, and all the while with the wind in your hair – but not too much of it. Related Video:
