Adjust the Rear Camber of Your Mustang With a Turn of a Bolt

By -

Specialty Products’ Mustang Rear Camber Arm improves tire contact with easy on-the-fly adjustments for 2015+ S550 Stangs.

Today’s Ford Mustang offers superior handling performance when compared to any past models, but there is always room for improvement. Adding sticky tires, stiffer springs and specially-tuned shocks will help you pony car run harder on a twisty track, slight adjustments to the rear camber can improve tire contact which leads to better grip when you are carving the corners. The problem in many cases is that adjusting the rear camber can be time consuming and difficult, but the team at Specialty Products just rolled out their new Rear Camber Arm package that makes suspension tweaks quick and easy.


The Specialty Products Rear Camber Arm for the S550 Ford Mustang was designed, engineered, tested and assembled in the Colorado. The arm itself is constructed of forged aluminum that weighs less than the factory upper control arm while being stronger while the rubber bushings maintain the factory noise, vibration and harshness (NVH) levels. In other words, this aftermarket component offers improved durability and rigidity when compared to the OEM piece without compromising NVH levels, so even without the adjustable aspect, the Specialty Products Rear Camber Arm is an improvement over the stock piece, but that is just the first advantage of the piece.

Where the Specialty Products Rear Camber Arm really outshines the stock piece is in the unique, adjustable fittings in each end. The inboard end features fixed adjustment with four distinct settings while the outboard end offers live, gradual adjustment. Each end uses an offset knuckle insert, which when rotated, makes small adjustments to the rear camber.

As the video above from the company YouTube channel shows, the inboard adjustment is set at the point of installation and locked into place while the outboard adjustment is designed to be tweaked as necessary. By turning the offset insert, the static position of the whole control arm changes, allowing for camber adjustments of -2 to +3 degrees, which in turns allows the tires of your Mustang to make better contract with the road surface under hard cornering and acceleration.

Best of all, for those of you who want to make quick adjustments at the track, you can make the live adjustments to the outboard end without removing the rear tires. This means that with a slim, open-ended wrench, you can add or remove camber in the pits or garage area without spending time removing the wheels, making this setup ideal for those S550 Mustang owners who want to get the best possible lap times from their modern pony car.

"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.

"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.

"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.

"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.

"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.

"Being based on Detroit," says Rall, "I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit's Woodward Avenue with the best muscle car crowd in the world.
