Having just announced the much-improved 2011 Shelby GT500 model, Ford is also debuting a new SVT Performance Pack for the car, which it says will deliver a 3.0-second per lap improvement on a 2.3 mile road course over the 2010 model.
So how is this possible? Well, along with the GT500′s 102-lb lighter engine, the Shelby team worked with Goodyear on a set of Eagle F1 SuperCar G2 tires, with a staggered 19-inch front and 20-inch rear fitment. Additional grip is also due to wider 265/40/19 tires up front. Ford claims the tires help deliver a 1.0 later g rating and a 7 percent improvement in braking.
“These tires are as close as you can get to a race car tire,” said Eric Zinkosky, SVT technical specialist. “We have a tire that’s way more capable, with better grip, is firmer and more race-oriented. From there, we tuned the chassis around it. The tires told us what we had to do.
Compared to the stock rollers, the new SVT light weight forged aluminum wheels weigh 4.7 lbs less up front and 2.8 lbs less in the rear.
Additional upgrades include stiffer springs that are 11 millimeters lower up front and 8 millimeters lower in the rear, while a longer 3.73 rear axle ratio is better suited to the car’s power on the track. Some aerodynamic improvements include a new rear spoiler Gurney Flap as well as a modified front end that delivers 25 percent better front downforce.
Pricing for the 2011 Shelby GT500 and the SVT Performance Package have not yet been released. Ford will officially debut the car and the package this Wednesday, February 10th at the Chicago Auto Show.

Official release after the jump:
Ford will announce details of the 2011 Shelby GT500 on Monday ahead of the car’s official debut at the Chicago Auto Show on Wednesday, but why wait until then? Ford’s webcast site has already given us a look at the car on a short video clip (which has now been removed). Screen captures of the video are, however, still available, showing the 2011 model with the SVT Performance Package.
Last week the 2011 Shelby GT500 order guide popped up online, confirming such new items as a completely aluminum block for the 5.4-liter V8. This should significantly reduce the vehicle’s weight, particularly over the front axle. Other highlights include the glass roof found on other Mustang models, as we as an SVT Performance Package, with such items as 19×9.5-inch front and 20×10-inch rear forged aluminum wheels, as well as 3:73 rear end (instead of the car’s standard 3:55). We’ve also learned that the GT500 will make an additional 10-hp for 2011, or a total of 550-hp.
Be sure to check back Monday for complete details of the 2011 Shelby GT500 and in the mean time, browse through our gallery of screen captures below or spec out your new 2011 GT500 using the leaked order guide.
