Vehicle Covered in this Guide
2015-present Mustang

Chassis Introduction
For 2015, the Mustang underwent its first major overhaul in over ten years. Gone are the traditional old school looks and character, replaced by the most refined and modernized Mustang yet. Dubbed the S550 chassis, it is new from the ground up and shares very little with the previous generation. The most notable change was the introduction of the independent rear suspension, making it the first time a mass produced Mustang left the factory with it. Despite the new body work and axles, the S550 shares the same wheel specs as the S197.

Performance Street & Track

Wider fitments for enhanced performance

Whether you enjoy spirited street driving or you're a weekend track warrior chasing lap times, these wheel & tire configurations are ideal for enthusiasts looking for a more dramatic improvement in performance. They are typically paired with performance oriented summer tires or track oriented R-compounds and this category includes both staggered and square configurations to best suit each individual drivers priorities, goals and preferences for their vehicle. 

We've optimized the offset of our wheels to work well with the stock fenders, however, a wide variety of tire compounds can be used and some may require negative camber to fit properly. See fitment notes under each tire configuration below to see if modifications are required. If you plan to track your car, we highly recommended dialing in negative camber regardless of whether your wheel/tire fitment requires it for fender clearance. Negative camber is vital for extracting the most performance and longevity out of your tires, and without the proper amount the outer shoulders of your tires will wear out prematurely and running tire costs will dramatically increase.

Hardcore Track & Race Fitments

All-out performance for fastest lap times

button-ordernow.png
51653638380_dbd196ca02_k.jpg

These wheel and tire configurations are best suited for hardcore track junkies and club racers that prioritize performance above all else.  With these wheels everything from extreme summer tires to full racing slicks are commonly used depending on your experience behind the wheel, class rules, etc.

Additional negative camber is strongly encouraged to maximize performance and tire longevity, and some of the more aggressive fitments will absolutely require it to prevent rubbing under suspension compression. Even with the appropriate amount of negative camber dialed in, some of the more extreme fitments can still scrub the liners under suspension compression and/or when turning the steering wheel to full lock. This is par for the course when pushing the limits of wheel and tire fitment. These fitments are not for someone who primarily will use this wheel setup on the street or in inclement weather. 

 

Square Configurations

Recommended for enthusiasts that want to mitigate understeer, improve turn-in, and rotate tires front & rear for extended life.

    • 25mm spacers, extended wheel studs, and open lug nuts are required up front for strut clearance
    • No spacers are needed on the rear
    • Select coilovers with offset housings allow the use of a 20mm front spacer. The only known coilovers are JRi, JRZ, and MCS. Please contact your suspension manufacturer to determine if your coilover not listed here has offset housings if you wish to run less of a front spacer. Most do not.

About Camber Plates 

s550.jpg

Adjustable camber plates do more than just aid in wide wheel and tire fitment. They provide increased grip and reduced tire wear by spreading the load evenly during cornering. Learn more in our blog article, The Positives of Negative Camber.
