If you have substantially lowered your vehicle chances are you have introduced bumpsteer. What is bump steer? Bumpsteer is changes in toe caused by suspension movement.

Every car has bumpsteer, however when you lower the vehicle you increase the amount of bumpsteer that occurs, if this becomes excessive you will begin to notice some unwanted vehicle driving characteristics. When you turn your steering wheel you are essentially changing the toe of the wheels to turn the vehicle.

Excessive bumpsteer is undesirable because it introduces unwanted steering inputs which means the suspension is steering the car instead of the driver. If your car is lowered and has tracking issues and less predictable steering behavior, you need a Steeda S550 Mustang Bumpsteer Kit for your 2015+ Mustang GT, EcoBoost, or V6.

Steeda S550 Mustang Bumpsteer Kit for your S550 Mustang GT, EcoBoost, or V6 will allow you to correct your bumpsteer geometry and can do so without requiring you to drill or modify your vehicle spindle. In addition, our Steeda S550 Mustang Bumpsteer Kit makes a great service replacement for your worn out, high mileage outer tie rods even if you do not have excessive bumpsteer issues.

Pick up a Steeda S550 Mustang Bumpsteer Kit for your 2015+ Mustang GT, EcoBoost, or V6 today and refresh your outer tie rods and improve your steering.

Note: Will not clear 16" wheels, nor OE 17" wheels (on S550 and 2019 Mustangs)

Bump Steer kit
This is such an easy mod! Did it in the garage in 30 minutes! No matter the measurements,. You will need an alignment! When I took it to Ford the mechanic came and told me he love Steeda parts! And my whole suspension is Steeda! After I got the Mustang back the smoothness of the steering and the feeling was on point.

A MUST HAVE for lowered vehicles!
Worth every penny of you are lowering your car. My Mustang feels like it's on rails, with no deflection on bumpy roads. Make sure you get an alignment after you install these! Thanks Steeda!

Excellent Product!
This bumpsteer kit was an instant attention grabber with my install shop as they were curious on the design and ease of installation. My alignment friend referred to this piece as "the best link I've seen." After driving over 100 miles with it on I have not noticed any bumpsteer and this is with my sport progressive springs on. I am more than satisfied with the quality and efficacy of this product, will recommend highly!!!

I'm officially a believer
Ok. So I know everyone has already made threads about their Steeda stuff, but I'm officially a believer! Suspension still was lacking so Steeda was contacted... Springs Sway bars Sway bar Billet Brackets Vertical Links Toe Arms Bump steer kit G-Track Brace IRS bushings MMR Camber Plates Performance wheel alignment The car is a go kart. Set the front sway bars to the center and rear to the lower settings, entry high speed turn is predictible, so much so I haven't learned the limits yet. The ass can be easily manuvered with throttle (Race mode/traction off). The body roll seems like it's gone (once the track wheels/tires come in I'll know for sure), it's unreal, I am in LOVE with the car now. This is the way it should've come from the factory for the PP cars. Really a learning curve, since now everything is souch more compossed. The IRS bushings and arms drastically changed the feel of the car on take off, the power actually goes to the tires (which I spin even easier now, even with camber still within factory specs.) There's not that feeling like the IRS wasn't properly fastened, it feels like it's built in to the body. Such a great mod. I'm ordering the IRS brackets as well, but I don't see how it can really improve further. It that good!! Steeda has my vote!
