Our Steeda engineers have been hard at work perfecting our S550\/S650 Mustang Rear Adjustable Camber Arms to improve even further on the factory IRS suspension components. The factory stock camber arm is made to withstand lots of force, but Steeda has found a way to improve the factory camber arm even more.\u003c\/p\u003e\n\u003cp\u003eThe bushings on the stock camber arms are soft, and just like any soft bushing there is deflection experienced under hard cornering. Bushing deflection causes your wheel and tire to lean outward, letting the tires lose camber while cornering. The loss of camber results in a reduction in grip and makes your powerful Mustang's handling less predictable. Make the most of the money you put into your alignment and tires by maintaining proper camber no matter where you are driving, with our Steeda Rear Adjustable Camber Arms.\u003c\/p\u003e\n\u003cp\u003eThe factory suspension comes with many bushings which also bind and hinder the suspension from articulating. Our Steeda rear camber arms get rid of two of these bushings, eliminating their artificial spring rate and ensuring that your suspension has the lowest amount of friction possible. Let your suspension articulate the way it should with our Steeda Camber Arms.\u003c\/p\u003e\n\u003cp\u003eOur engineers have gone above and beyond with design, development, simulations, and testing to provide our customers with the highest-quality adjustable camber arms on the market. Our Steeda Mustang Rear Adjustable Camber Arms can typically be adjusted from +1.5 degrees camber all the way to -3.5 degrees camber, more than enough adjustability for any street or race set up. Due to its natural bend design, our Steeda camber arms were brutally strength-tested because of the amount of load this particular suspension component takes on a daily basis.\u003c\/p\u003e\n\u003cp\u003eOur camber arms completely replace the soft factory bushings with nylon-coated spherical bearings which prevent dirt from penetrating the bearings and ensuring the rod ends will never need to be replaced. The Delrin on one side and spherical bearing on the other side completely rids the deflection of the factory bushings - reducing deflection allows you to maintain proper camber during hard cornering without increasing NVH at all. Maintaining proper camber during cornering allows you to prevent the loss of grip and allows for a more responsive and predictable handling car. This leaves the handling feeling more direct and positive while also making the car much more capable on the track. Stop throwing away money by replacing your unevenly worn tires due to improper rear camber - replace your stock camber arms with Steeda and never look back.\u003c\/p\u003e\n\u003cp\u003eOur Adjustable Rear Camber Arms are manufactured from Aerospace grade 6061 aluminum for incredible strength. Spherical nylon-lined bearings are made with specific preloads imparted on the bearing, ensuring lowest amount of bind on the ball bearing as possible. One of the best features of our camber arm is the adjustability we give you without having to take the part off the car. To adjust your rear camber setting all you need to do is jack up your car, turn the middle nut and you're good to go.\u003c\/p\u003e\n\u003cp\u003ePurchase your Steeda S550\/S650 Mustang Rear Adjustable Camber Arms for your 2015+ Mustang GT, EcoBoost, or V6 at Steeda Autosports today!\u003c\/p\u003e\n\u003cp\u003eAlso fits the S550 GT500\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003csection\u003e\u003cstrong\u003eProduct Benefits\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e5° Camber adjustment range, typically from -3.5 degrees to positive 1.5 degrees\u003c\/li\u003e\n\u003cli\u003eIncreased cornering performance, more predictable handling\u003c\/li\u003e\n\u003cli\u003eGain rear grip\u003c\/li\u003e\n\u003cli\u003eIncrease vehicle reaction time\u003c\/li\u003e\n\u003cli\u003eOn-car adjustability\u003c\/li\u003e\n\u003cli\u003eNo increase in NVH\u003c\/li\u003e\n\u003cli\u003ePrevent uneven tire wear on lowered cars\u003c\/li\u003e\n\u003cli\u003eEasy 45 minute install\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCamber arms offer 5° of adjustment.

Being the first production Mustang with an IRS since the 03\/04 Cobra's, we knew there would be a great opportunity to capitalize on Ford's new piece by giving it the Steeda advantage. As with any suspension system, deflection is an issue if it's present. Anytime a piece is moving, twisting or vibrating when it should be stationary is a major problem. One of the areas team Steeda wanted to focus on was the rear IRS subframe.\u003c\/p\u003e\n\u003cp\u003eAs you have seen with our IRS Subframe Bushing Support System, it limits the movement of the subframe by filling in the voids of the OE bushings.

This is where the Stop the Hop Drag Ultimate Kit comes in. Our team of engineers got together and came up with the best parts for eliminating unwanted wheel hop in the new S550 Mustang to help you get the best time possible at the drag strip. A kit that gives you the fundamental foundation for ultimate traction and suspension compliance. As we have explained before, the factory IRS subframe, (often inaccurately referred to as a cradle), mounts to the S550 chassis with 4 mounting locations utilizing 4 soft rubber bushings with plenty of voids, even in the bolt holes. The kit we put together addresses these issues and more.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFirst is our Alignment dowel kit. This fills the factory bolt hole voids with CNC machined delrin inserts that will square up the rear subframe to the chassis. By filling these voids we are also limiting the side to side and front to back movement of the subframe that is present under hard acceleration and braking.\u003cbr\u003e\u003cbr\u003eSecond is our tried and true IRS Subframe Bushing Support System. This 8 piece kit was a first of its kind in the performance aftermarket and so innovative and popular we patented its design! Made in-house from billet 6061 aluminum and featuring stainless steel hardware, this kit fills all the factory voids in the IRS subframe mounting locations. Its job is to prevent up and down movements of the subframe.\u003cbr\u003e\u003cbr\u003eThe 3rd component of this kit is the strongest support brace for the S550 IRS on the market!! Made in house from chrome-moly steel, this brace is designed to support the factory subframe by directly tying it into the chassis at key mounting locations. Using factory mounting locations on the factory frame, this 5 point brace supports the front factory mount and the lower control arm mount as well. A simple bolt-in design, this brace ties the subframe to the chassis in the best possible way.\u003cbr\u003e\u003cbr\u003eThe 4th piece is Steeda's rear lower control arm spherical bushings which are recommended for all drag race applications. If you drag race your GT, EcoBoost, or V6 Mustang our rear lower control arm spherical bearings will play a huge role in eliminating deflection, ensuring your tires hook immediately upon acceleration. Our spherical bearings stop your S550 from building negative toe on launch. In addition to eliminating deflection and compliance of the factory bushings, our spherical bearings will also eliminate the spring rate of the factory bushing which does not allow the suspension to articulate up and down freely.\u003c\/p\u003e\n\u003cp\u003eThe 5th piece included in this kit is the impressive Steeda Adjustable Rear Camber Arms. These help you dial in that track alignment, correct camber after lowering your Mustang, and help you get a better contact patch at the track. These are CNC machined from 6061 aluminum and offer +2 through -5 degrees of adjustment.\u003c\/p\u003e\n\u003cp\u003eSteeda's Rear Toe Links are the 6th item in the kit. They help you improve your launch and allows you to control the toe of your Mustang during launches. Improve your 60-foot times and get down track faster with this upgrade from Steeda.\u003c\/p\u003e\n\u003cp\u003e7th in the kit, the Steeda Billet Vertical Links with Delrin Bushings prevents deflection and stiffens the rear of your S550. This CNC machined 6061 billet aluminum piece is a great step up over the stamped factory piece. Reducing bushing deflection will help you put more power to the ground, while also preventing unwanted movement and wheel hop. Bushing deflection from the stock rubber bushings can cost your Mustang energy at launch and will hold your Ford back from reaching its full potential.\u003c\/p\u003e\n\u003cp\u003eThe 8th and final piece of this kit is the Ford Performance Knuckle to Toe Link Assembly. This replaces the factory rubber bushing and, like above, reduces deflection. This part will improve the handling and help your Mustang perform at its best.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNOTE: Steeda IRS Subframe support braces will not fit convertible\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eKit Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan\u003e555-5754 \u003c\/span\u003e- Steeda IRS Subframe Support Braces\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e555-4438 \u003c\/span\u003e- Steeda IRS Subframe Alignment Kit\u003c\/li\u003e\n\u003cli\u003e555-4437 - Steeda IRS Subframe Bushing Support System\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e555-4123 - \u003c\/span\u003eSteeda Rear Adjustable Camber Arms\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e555-4121 - \u003c\/span\u003eSteeda Billet Aluminum Vertical Links with Delrin Bushings\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e555-4120 - \u003c\/span\u003eSteeda Adjustable Rear Toe Links\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\u003c\/strong\u003e555-4117 - Steeda Rear Lower Control Arm Spherical Bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eM-5A460-M -\u003c\/span\u003e Ford Performance Knuckle To Toe Link Bearing Assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eProduct Benefits:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eEliminate wheel hop\u003c\/li\u003e\n\u003cli\u003eEliminate subframe movement\u003c\/li\u003e\n\u003cli\u003eSimple install\u003c\/li\u003e\n\u003cli\u003eSquares subframe to the chassis\u003c\/li\u003e\n\u003cli\u003eNo permanent modifications\u003c\/li\u003e\n\u003cli\u003eBetter 60-foot times\u003c\/li\u003e\n\u003cli\u003eAllows you to dial in the suspension for faster quarter-mile times\u003c\/li\u003e\n\u003cli\u003ePuts more energy into launching your S550\u003c\/li\u003e\n\u003cli\u003eGives you more control over your suspension with adjustable components\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Steeda","offers":[{"title":"Default Title","offer_id":48222741168372,"sku":"555-2129-D","price":2289.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/6633\/6244\/files\/555-2129-D__60518.jpg?v=1778725782"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0811\/6633\/6244\/collections\/s550_e2727968-e9ab-4963-b37b-1fd5c2c38440.jpg?v=1778199398","url":"https:\/\/radfastperformance.com\/collections\/rad-s550-build-parts.oembed","provider":"RadFast Performance","version":"1.0","type":"link"}
