        Shelby cs1 20x9,20x11 gunmetal

        I was looking to get another set of wheels to replace my 20x8.5,20x10 wheels I already had on the car.i knew i wanted something either black or charcoal/gunmetal and 9-10 wide in front and 10.5-11 in the rear so I said I’d give these a try.these looks far better in person then in pictures and the spoke design make them easy to a running a 255/35/20 in front which is perfectly flush with the wheel and these also fit Brembo 4 piston brakes,got 295/35/20 in the rear and even tho 295 is what’s recommended on the site 295 is almost too narrow for this wheel.when installing the rear you will notice that the wheel is very close to the bumpstop bracket and rear shock and that it isn’t gonna fit but once you lower the car to the ground it will fit,best to keep the suspension loaded when installing.only thing I don’t like about these wheels is I wish they made the fronts a little wider,20x9.5 and that these wheels are pretty heavy due to there size around 37lbs for the rear even tho the site claims 40.9.

        B/A Looking Rims

        These look super on my ruby red 2014 GT500! Tires are a little noisier than stock, but I can live with it. Speedometer change compared to stock tire size is not enough to mess with.

        Most Beautiful Wheels Possible

        These are the most beautiful wheels anyone could possibly put on their Mustang. Not to mention, the amount of rubber on the road is amazing for traction and control. The 11" wides on the back really grip and let you know that your beast is ready to go. I could not be happier with the quality and look of these wheels.

        CS1 20x11" Rear Rim for 2014 Shelby GT500

        I wanted to purchase another set of rims for my car as the tires that come from the factory are only rated down to 40 degrees F. I drive the car year around and needed tires for cold temperature driving. I didn't want to throw away the factory tires or have the expense to change them out every season. Purchasing a new set of rims was the best option for me. I wanted to have the widest tires I could for the rear and wanted a front set to match. I also wanted to keep the overall diameter of the tire and rim as close to factory as I could to prevent high errors on my speedometer. These rims look great on my black Shelby and are easier to clean than the factory FRPP rims. I purchased 315/35-R20 Continential DWS tires for the rear and the grip of the car is greatly improved over the factory tires. Also the tires handle much better on wet/cold roads. With this tire/rim combo the car pulled a 1.12G on the skid pad (completely factory car except the tire/rim combo). I purchased the CS1 20x9" rims for the front and placed 265/35-R20 tires on these. This combo actually gives the car under steer. If purchasing this combo I would recommend 275 tires for the front. On another note the rear rim/tire combination is very tight. The inside fender lining separated slightly from the steel wall and I had to cut this section out to mitigate the slight rub. Overall the rims look great and I really like the cobra emblem in the center.

        Shelby CS1 gunmetal

        This is a great product. Turns heads everywhere I go. I have the Sterling grey GT so they look like they were supposed to go on this car. They're are little on the heavy side but thats to be expected with that big of a wheel/tire combo. Overall very pleased with the product. If you have Sterling Grey 5.0 I highly recommend!

        CS1 Wheels

        The Shelby CS1 wheels are a true head turner, the look is amazing and photos do not do these wheels any justice, these wheels are what you need to look at in person. Had no issue with putting a 295/35ZR20 Michelin Pilot Super Sport tire on the rear with these 20x11 CS1 wheels, no rubbing issues, no clearance issues.These wheels are heavy compared to most other aftermarket wheels but these do clear the big brake package like Brembo, Wilwood, Shelby Extreme brakes. Many compliments on the wheels while at a red light or parked in a parking lot. They look fanstatic on my Shelby GT500 convertible 2012. I purchased the CS1 20x9 wheels for the front and 20X11 for the rear. I currently have 275/35ZR20 tires mounted on the 20x9 CS1 wheels and 295/35ZR20 tires mounted on the 20x11. You can go up to a 305 without any issues and some people have used a 315 on the rears depending on if the car has been lowered or not but just be sure you have an adjustable panhard bar installed to center up the rear.

        great looking big wheel

        some how the rear wheels showed before the fronts and they were damaged. Called AM and they sent two more wheels out that day. When everything got to the house and in good order i loaded them up and off to the tire shop. they said the 20x11 for the back would not fit. i called AM and they assured me they would so i told the shop to try it. i also told them that i have heard that in the air they look like they won't fit but once on the ground they are fine. so they did and it worked.

      5 Top Rated Questions

      Sizing clarification. I notice the recommended size is 295/35r20 but this would result in a tire that is over 28" high verses a 295/30r20 that would be equal size to the staggered matched front. Is the sizing recommendation correct, because I am also not able to easily find the recommended size on most tire spots?

      • Yes, the 295/35R20s will fit the 20x11 wheels without any issues. Now the sidewall will be slightly taller when compared to the 295/30, but this should not affect clearance as long as the drop is not to steep (if the vehicle is lowered).

      Will there be rubbing issues with a 1.75" drop Front and 2" in the back with and this wheel/tire setup? I dropped the vehicle 1.75 inches in the front, 2" in the back.

      • As long as the car is not dropped more than 2" you should not have any rubbing or fitment issues.

      Clearance issues? Any clearance issues with the Eibach Springs Pro-System Plus Suspension Kit?

      • No you will not have a problem with that system I have a 2007 mustang gt with 20x9 255/35/20 front and rear 20x11 295/35/20 and so far no problem one thing to keep in mind you will need to push up on the axle on order for the rear wheels to fit or else the they will hit the bump stop bracket to get a better idea check out my car In the pictures its the red one with the hood pins

      Will this wheel package work with the Ford handling pack that will have a 1 inch drop over stock?

      • yes this will work.. once installed you will still have about a 2 inch gap between the top of tire and lip of wheel well.. The low pros help a lot with this clearance issue. As long as you dont mind having the thinner walled tire you will be fine.. Ordering myself a set soon and also have the Ford racing handling pack for my 2013 GT. Now my answer is that of the GT coupe. I am unsure of the wheel clearance on the convertible model if there is any difference in wheel well size, but i would be almost positive that saying wheel well on both convertible and coupe models are the same. Definately a good combo and the look is very aggressive and sporty. Good luck with everything you have planned for your pony and safe ventures!
