Stop Wheel Hop On Your 2015-2017 Mustang

There’s no question that many Mustang owners and enthusiasts are fans of the new independent rear suspension on the S550 Mustang. For those out there that aren’t convinced of this newly revised suspension, we urge you to get out and drive one -- it’s truly a completely different experience from ride comfort to the overall handling experience.

However, one major downside to IRS is the tendency for wheel hop during hard acceleration in a straight line. As the tires fight for grip against the asphalt, the wheels have a tendency to move up and down sending violent vibrations through the driveline and body of the car. Not to say that Mustangs with a solid rear axle don’t have this issue because they certainly do, but independent rear suspension makes wheel hop a lot easier to occur.

Thankfully companies like Steeda Autosports have stepped up to the plate and put the research and development into finding out what exactly causes the wheel hop on the S550 Mustang and more importantly, how to fix it with a few select parts. If you check out their YouTube video, Steeda goes in depth to show what causes the wheel hop and how some of these parts will help alleviate the issue.

Steeda IRS Subframe Bushing Support System

One of the main culprits of wheel hop is bushing deflection. The rear subframe in the S550 is mounted to the body of the car with a series of bushings. These bushings are designed with a fair amount of deflection built in for minimal noise, vibration and harshness, or NVH, along with overall comfort levels.

The IRS Subframe Bushing Support System from Steeda is a series of shaped metal supports that slide around the existing bushings for added support; all without increasing NVH!

Steeda Rear IRS Subframe Support Braces

Subframe connectors have been around as long as muscle cars have been going down the dragstrip. These IRS Subframe Support Braces do just the same in helping the overall structural integrity of your Mustang.

By adding two additional support points to the rear subframe on either side of the car, you’re exponentially strengthening the connection between the subframe and the rest of your car. The result is less wheel hop, less body roll and more traction.

The factory vertical links on the S550 are small and relatively weak. Due to this design, the factory links can flex and as discussed before flexing or deflection is bad, especially to certain suspension components. By adding these 6061 Billet Aluminum Rear Vertical Links to your S550, you’ll be able to eliminate that flex and provide additional rigidity to your rear subframe; thus aiding in eliminating that pesky wheel hop.

In addition to the vertical links and other suspension modifications, it may be a good idea to add a set of toe links onto your build list. With the additional adjustability that these Steeda Rear Toe Links provide, you’ll be able to surely dial in your Mustang’s rear alignment to precise specs to match your driving style. Whether it’s an aggressive camber for road course racing or a moderate setup for the occasional autocrosser, you can never have too much adjustability!

Steeda IRS Subframe Alignment Kit

Last but certainly not least on the Steeda lineup is the Subframe Alignment Kit. It’s been known that the rear subframe on the S550 can come out alignment from the factory. This is most apparent when you would unbolt your subframe to install springs or subframe bushing supports, for example, and the bolts won’t line up with the holes properly. The addition of this Steeda Subframe Alignment Kit will allow you to keep your rear end square so your local shop can properly do an alignment that stays true over time.

In adding all of these suspension mods from Steeda to help alleviate wheel hop, it may be a good idea to pick up lowering springs and a set of sway or anti-roll bars to complete your suspension overhaul. After adding these modifications to your S550’s suspension setup, you’ll surely be on your way to carving corners like never before!

It was said that Ford and Ford Performance set the benchmark for the 2015 Mustang to handle better than the outgoing platform’s BOSS 302. With the addition of these suspension parts from Steeda, the opportunities are virtually endless when it comes to conquering the autocross, road course or even some twisty back roads!
