Introduction |
After reviewing hundreds of surveys submissions, it was clear our top priority needed to be the release of an 18x11” Mustang fitment. This new wheel specifically caters to the S197 and S550 owners who want a rotatable square fitment or a wider rear to create a stagger.
Our research and test fitments show a 52mm offset will be most effective. During the feeler phase we’re still open to feedback and we may modify our final proposed offset +/- a few millimeters if any convincing evidence comes to light.
Don’t keep your feedback in the dark by messaging us directly. Share your feedback with us publicly via the forums or using the discussion tab here so we can get a group conversation going for fitment questions and product feedback.
Be sure to check out the fitment guides we’ve posted below.

Fitment Information |
Front & Rear: EC-7 18x11" ET52
Weekend track warriors and racers alike prefer maximizing grip while controlling costs. The 18x11” square fitment allows you to install wide track oriented tires at all four corners that can be rotated front to back.
Keep in mind, a true rotatable square fitment means hubcentric spacers will be required on the front axle to ensure proper inner strut clearance. Spacer thickness will vary depending on your suspension type, tire brand and size, vehicle ride height, and whether you are using camber bolts or camber plates to dial in negative camber. Anytime spacers are installed on a vehicle, it is also necessary to install extended studs which provide the necessary thread length for proper spacer installation. With these spacers installed, the 18x11” ET52 will successfully clear the S550 PP Brembo BBK, S197 14” and 15” GT500 Brembo BBK’s and an assortment of popular aftermarket BBK’s from reputable manufacturers like Brembo, StopTech, and AP Racing. If you have brake clearance questions, be sure to contact our product specialists.

Many enthusiasts like the idea of maximizing rear end grip with an 11” wheel, but will prefer to pair them with our existing Mustang EC-7 18x10” ET43 up front. Whether you are enjoying your Mustang predominantly on the street, or simply prefer running a staggered fitment for a lighter steering feel, we’ve got you covered. The existing 18x10” ET43 EC-7 wheels clear the S550 PP Brembo BBK, S197 14” and 15” GT500 Brembo BBK’s and an assortment of popular aftermarket BBK’s from reputable manufacturers like Brembo, StopTech, and AP Racing with no spacers required. If you have brake clearance questions, be sure to contact our product specialists.

When offered, free shipping is available to members in the 48 mainland US states. Buyers who have product shipped to Alaska, Hawaii, APO/FPO, and International destinations will receive a flat shipping credit that applies towards the actual calculated cost of shipping. Shipping discounts will be listed on the sign-up page. Non-mainland, APO/FPO, and international customers should contact the vendor for a shipping quote, and to pay for their order.
GroupBuyParts.com supports calculating exact costs for international orders. Customers can view their final shipping costs prior to ordering including special shipping discounts. Shipping costs do not include importation taxes and duties. The buyer will be responsible for paying all taxes and fees to the freight carrier directly.
Some products may sell out. Availability is limited to vendor’s supply on hand. Orders will be fulfilled on a first-paid-first-fulfilled basis. Within 48 hours of placing an order request, the vendor will contact you if the product you ordered sold out, or went on backorder. You will have the option to modify your selection, accept the wait for new stock, or cancel or order.
Group Buy orders may only be exchanged if the product is defective. There are NO refunds on Group Buy orders. All orders are considered special order due to the unique production, fulfillment, and pricing of product. They do not share the same terms and conditions as traditional e-commerce purchases.
