5 x 4.5 - same for all Mustangs of that year.
GT500 rims will swap onto any other Mustang built in 2009.
There are two models available in the Shelby Gt500. Shelby GT500 - 500 HP / 480 torque Shelby GT500 KR - 540 HP / 510 torque
500 horsepower at 6,000 RPM and 480 ft/lbs torque at 4,500 RPM according to the 2009 GT 500 Owner Guide supplement
a 2013 shelby gt 500 gose aproximetly 200mph
I was looking at the 2009 Ford Mustang Shelby GT 500 supplement but it doesn't show the top speed , for the 2010 version it shows that it is electronically limited to ( 155 miles per hour )
( 500 horsepower ) for the 2008 Mustang Shelby GT 500
because its horsepower is 500
A shelby GT 500 has a 427 CI
Bolt patern is 5x114.3, got to this web page and see others similar; http://www.ronalusa.com/cars.html

The engine horsepower rating was 500 hp or better

The 2010 Ford Shelby GT 500 has ( 540 horsepower )
