      Modern Shelby Muscle. Carroll Shelby carries the proud pony tradition into the new millenium with an innovative new wheel design, introducing the Shelby CS1. This throughly modern wheel features a unique trident five spoke design and a European style flange-less lip for awesome sleek styling. Shelby Snake center cap included.

      Machined Face With Black Inserts. The velvet smooth look of the machined aluminum face makes for an intense contrast against the black inlays on this wheel for an incredibly sharp presentation. These machined wheels feature a satin clear-coat finish to protect against the hazards of road chips and pitting.

      Application. This Shelby CS1 Wheel fits the rear only of the 2005-2009 Ford Mustangs. Stagger with 20x9 on the front for an aggressive muscle car stance and improved traction.

        Fits with the Perfect Offset! Excellent quality..

        Purchased the 20x11 CS1 wheels to match the 20x9s i already had. Wanted a staggered setup with a larger tire for better traction. Went with the Nitto NT555 G2 tire 305/35/20 on the Rear and 275/35/20 for the Front. Will probably go with a 315 for the rear next time. Wheels fit perfect and match the offset of the 20x9. Takes the extra 2" of tire and wheel towards the inside of the car. Looks tough now! Excellent quality and fast shipment as always from American Muscle!

        Just got these mounted with Michelin PS4 tires. They look great prefect fit on my 2014 GT500. Tire fill valve mounted on the inside of the rim for clean look, but difficult to access.

        These are very nice quality, and look great on my 08 GT500. I really liked the look of the original SVT wheel, but these let me update the look of the car while keeping an authentic Shelby wheel.

        Baby needed new shoes

        These rims were the perfect match for my GT... It took a while to get them, but they were worth the wait.

        Love the staggered look

        Wheels and caliper covers look great. I went with staggered setup and 11" wide wheels on the rear worked out just right.

        CS1 Wheels on a 2009 GT 500

        These wheels will fit a 2007-2009 GT 500 with 315 35 20's without removal of any other part of the vehicle. You will have to lift vehicle, then place jack stand under axle and lower slightly in order to "load" the suspension a bit. The wheels will contact/rub the factory bumpstop brackets if fully extended/axle is not supported. BUT when lowered, will not have contact with any component on factory suspension if your axle is true (with factory panhard, which I have). Highly recommend bumpstop relocation brackets, which I am about to do, for the extra clearance and no need to load axle. My car is not lowered. Factory height. Overall wheels are excellent, look great on the car, good quality and fit. Proper offset right from the start from American Muscle. Excellent, almost immidiate processing and shipment, exactly as I ordered it. No issues whatsoever. Look great on the car, as it has no chrome, and fits with the machined look. Chrome is for the older cars!

      will i need to modify my suspension on a 2012 mustang v6? i currently have a 1.5" drop on my car and wanted to know if these would fit without rubbing?

      • Depending on the spring rates and the tire size used, the tire could potentially rub with the Shelby CS1 Black Machined Wheel in 20x11. If you would like to give us a call with your specific suspension information, we would be more than happy to confirm the fitment.
