Review & Installation Video

Review & Install Video

Hey guys, Stephanie with AmericanMuscle.com, and this is my review of the SR Performance Bump Steer Kit for the 2015 to '16 S550 Mustang. This is going to be for anyone who has a lowered S550 or is thinking about lowering theirs. Keep in mind, any time you lower your Mustang, you're essentially changing the geometry of your suspension, which can create a bump steer problem or, basically, an undesirable change in the toe angle. And that's what this part's designed to do, keep everything in line and stop that bump steer.So looking at this kit, I'm seeing a few different things. I see tapered shafts on the rod end, so you don't have to drill out the spindle for the install, and I also see a handful of spacers. This kit actually has a few more spacers and I think, actually, even more adjustment on the tie rod end here, than the other kit that's on the site. And this kit costs less.Speaking of cost, this kit's under $200 and, like I just said, it's less expensive than the other option. It actually gives more adjustability and it seems like it's built solid.When it comes to the install, guys, I don't say this too often, but I do recommend taking this to the shop unless you have prior experience in this area. You're going to have to get the car aligned after the install anyway, so you can just drop it off and get everything done in one shot. This is a three out of three wrenches on the scale, and if you do decide to do this at home, it's probably going to take a full day's work. And just keep in mind that a tie rod end separator could be helpful, and make sure you have a torque wrench to keep everything in spec. Don't forget, if you do this at home, while you can get your toe close to where it needs to be, you should still go for an alignment after the install.So if you're lowering your Mustang, or you already have, then this is a part that you should really consider to keep your S550 suspension in check. Like I said, it's solid and actually offers more adjustability than the other more expensive option on the site. You can find this kit and all of your other Mustang parts right here at AmericanMuscle.com.

Improves Handling. Correct your S550 Mustang's front end suspension geometry and eliminate bump steer for track car like handling with a SR Performance Fully Adjustable Bump Steer Kit. Replace your stock, non-adjustable components and gain better, more predictable cornering and handling.

Adjustable. SR Performance's fully adjustable kit provides a wider range of adjustment than other kits, allowing you to fine-tune your suspension for improved steering response and crisp cornering.

Ideal for Lowered Mustangs. The SR Performance Bump Steer kit is the perfect complement to a set of aftermarket ball joints or caster/camber plates, allowing for a perfect alignment and track car like handling.

No Drill Installation. Unlike other kits which require you to drill your spindle out during installation, SR Performance Bump Steer kit features spherical rod-ends with tapered shafts for an easy installation with no drilling necessary.

Application. This SR Performance Fully Adjustable Bump Steer Kit is designed to fit all 2015-2020 GT, EcoBoost and V6 Mustangs.

NOTE: Bump Steer is a change in toe angle caused by the suspension moving up or down. Bump Steer is built into the geometry of the suspension and steering system, and has nothing to do with turning the steering wheel. The effect of bump steer is for the wheel to toe-in or toe-out when the suspension moves up or down. This toe change or "steering" occurs any time the suspension moves, whether it is from body roll, brake-dive, or hitting a bump in the road. Bump Steer is undesirable because the suspension is steering the car instead of the driver. To fix a bump steer problem, you need to alter the height of the outer tie-rod relative to the steering rack with adjustable tie-rod ends, also known as a bump steer kit.

      1 Top Rated Question

      What are the recommended setting for a lowered mustang? The instructions aren't very descriptive on how to divide the spacers.

      • When installing the SR Performance Bump Steer Kit, the spacers should be arranged to keep the tie rod as close to parallel to the lower control arm as possible to eliminate bump steer.

          Must have for lower cars!

          I have Air Lift on my stang and this was the last part in a long list of suspension mods. You cannot simply lower your mustang and expect the suspension geometry to not change. This bump steer kit is a must have for probably anything lowered past 1". Installation is pretty easy. Keep in mind what your suspension objective is when setting the number of spacers. Driving at ride height and driving slammed would require completely different spacer orders. Unfortunately this will require an alignment and you should really get an actual bump steer correction as well.

          Amazing couldn’t believe I waited this long

          I lowered my Mustang GT 2016 premium (non performance pack) and got the ford performance suspension. For 2 years I couldn’t figure out why my car would track and follow the grooves of the road and get launched at times. It did feel violent on the freeway. After installing this and an alignment to the track pack, she handles like a go kart.

          SR performance bump steer kit

          I'm still getting used to the feel of these. But I do find cornering is much better. My steering wheel doesn't even move while cornering even on bumpy roads. I'm pleased with this kit. Had my car aligned and Can't wait to test them at Willow.

          Works but it's poor quality

          Definitely reduces bumpsteer over small bumps but it won't fix your roads. Mine came loose while driving and it turns out the nut got stripped in the process. I had to bang the bolt out of the nut with a hammer. Never again will I use SR performance parts.

          Improvement

          It does help with steering some. With my car lowered I don't get the uncontrolled steering when going over a bump.

          Reduced my Bumpsteer!

          I have a lowered daily driven 15 V6. The roads are not the best here in NC and some bumps in the corners made the front tires annoyingly change direction without input from me. Needless to say after installing this kit and getting an alignment its now more predictable and less surprising when faced with bumpy roads. Good quality and price compared to the competition however the spindle is a bit lengthy and barely clears the internal diameter of the 17in stock wheels. I would recommend this kit to those with 18 " wheels.
