2015-17 Mustang GT suspension and chassis

We’re flexible regarding chassis and suspension components, accommodating your brand preferences. We’re prepared to work with you if you want us to begin from scratch or pick up where you’ve left off.

We’ve created ‘stage’ packages to simplify devising your ideal setup. These assist in outlining your chassis development stages. However, we don’t insist on following our staging system, we understand the potential of partnering with manufacturers beyond our knowledge, recognizing the added value and performance that can result.

Spacers Package

Adding wheel spacers is a modification that will provide a wider stance and change the appearance of your vehicle. It’s incredibly effective with minimal drawbacks – the primary one is your wheel studs will need to be shortened.

To help you make an informed choice, we’ve included a “return to stock price.” This covers the cost of installing 20 new wheel studs into your current hubs if you decide to revert to the original configuration.

We prefer collaborating with the manufacturers that give great results! Steeda stands out as one of the leading independent names in performance Ford vehicles, with a 30-year legacy and a close partnership with Ford Motor Company. Steeda’s development is second to none, road and track proven results on many of their owned test and demonstrator vehicles and their in house test track.

MAP Essentials Chassis Package

Ford has a nasty habit of supplying the Mustang with poor wheel-alignment from the factory, and as a result, we have seen cars as young as 5000 miles on the clock need new front tyres because of severe inside tyre wear.

This package is designed to address that common issue. We have put it together for those who are not particularly bothered about improved performance but do want their car right. So we supply and install a set of Camber Bolts to give us the adjustment we need. Additionally, we recommend including the Steeda IRS base kit for improved stability on UK roads.

Stage 0 Includes

  • Eibach Front Camber Bolts
  • Full 4 Wheel Geometry setup
  • Installation Labour

Stage 0.5 Includes:

  • Steeda Rear Subframe Alignment Kit
  • Steeda IRS Bushing Support System
  • Eibach Front Camber Bolts
  • Installation Labour
  • Full 4 Wheel Geometry setup

Chassis stage 1

Now for the exciting stuff. Basically, if you enjoy the performance of your Mustang and she is a performance car to you (you’d have bought a diesel 3 series if not, right?) then this is 101, how it should have been.

This will instantly improve your Mustang’s ride quality, giving you newfound confidence in its handling; if you’re a performance enthusiast, this package is tailored for you. Instead of cautiously approaching a roundabout, you’ll tackle it with wide eyes and a grin. It’s not an exaggeration; this package truly transforms your driving experience.

The Stage 1 package includes:

  • Steeda Performance Springs
  • Steeda Rear Subframe Alignment Kit
  • Steeda IRS Bushing Support System
  • Camber Bolts
  • 4 Wheel Geometry Setup

*See the video for information on spring options.

Chassis Stage 2

Now that we’ve covered the “should have been like that all along” aspect, let’s delve into the next phase.

The Mustang, straight from the factory, was designed as a comfortable cruiser; Ford prioritized comfort and succeeded. However, if you want to enhance its cornering capabilities, this step involves eliminating the chassis deflection and creating a better connection between the driver and the road. This is where bracing comes into play. These modifications will significantly improves your car’s overall stability by reinforcing and securing the major chassis components that tend to have substantial deflection.

Chassis Stage 1 Includes:

  • Ford Performance strut tower brace (Not applicable with screw-type chargers)
  • Steeda Ultralite 2 Point G Trac Brace
  • Steeda Mustang IRS Subframe Support Braces
  • Steeda Jacking Rails
  • Professional Installation

Chassis Stage 1 (Convertible) Includes:

  • Ford Performance strut tower brace (Not applicable with screw-type chargers)
  • Steeda Ultralite 2 Point G Trac Brace
  • Steeda Jacking Rails – Convertible
  • Professional Installation

While worthwhile on its own, when combined with the Stage 1 package, these modifications lay the groundwork for taking your Mustang’s performance to an entirely new level.

Chassis Stage 3

With the car now braced up for the corners, this is the part where we account from some straight line and launching capability. Stage 3 focuses on stopping wheel hop under launching or hard acceleration. Eliminating wheel hop means you can ensure there will be no damage caused by the wheels hopping as this is essentially shock, and also makes wheelspin enjoyable and smooth without sounding like you’ve hit 7 potholes.

Polybushes are typically recommended for naturally aspirated power levels.

For forced induction power levels, Delrin bushings are recommended. Nonetheless, our recommendation extends to those planning to add a supercharger to their setup.

Packages Include:

  • Steeda Billet Aluminium Vertical Links
  • Steeda Adjustable Toe Links
  • Ford Performance Toe Link Bushings
  • Installation Labour
  • Four-Wheel Geometry Setup

Chassis Stage 4

With the wheel hop now kept at bay, and you can feel what the car is actually doing in the corners, we can now look to further improve the cornering ability. The Mustang is a pretty big car compared to most modern sports cars, this means more weight, and more weight means more body roll. Upgrading the anti-roll bars means when you’re mid corner, the car feels as flat as it did on the straight before the corner. This gives the driver more confidence, feedback and higher cornering speeds.

The hardcore package offers the ability to achieve zero pre-load on your suspension by utilizing adjustable drop links.

Fast Street Includes:

  • Steeda Front Anti-Roll Bar
  • Steeda Rear Anti Roll Bar
  • Steeda Front ARB Billet Mounts
  • Steeda Rear ARB Billet Mounts
  • Installation Labour
  • Four Wheel Geometry

Hardcore Includes:

  • Steeda Front Anti-Roll Bar
  • Steeda Rear Anti Roll Bar
  • Steeda Front ARB Billet Mounts
  • Steeda Rear ARB Billet Mounts
  • Steeda Front Adjustable Roll Bar End Links
  • Steeda Rear Adjustable Roll Bar End Links
  • Installation Labour
  • Four Wheel Geometry

 

Chassis Stage 5

Stage 5 is now about taking the vehicles weight management one step further, by upgrading the suspension dampers we can further control how well the car performs when cornering, switching direction and for the high power cars even the way it delivers the power to the ground.

  • ProAction Non-Adjustable: A choice that optimizes street performance without adjustability, balancing comfort and improved handling.
  • ProAction Adjustable: This option allows you to fine-tune your vehicle’s suspension according to your preferences. It offers enhanced control over handling characteristics while maintaining street comfort.
  • ProAction Active: This advanced choice introduces active damping technology, adapting the shock absorbers to real-time changing road conditions. It delivers superior ride quality and performance.

Each option caters to varying preferences and requirements, ensuring you can tailor your vehicle’s suspension setup for your desired level of street performance.

Package Includes:

  • Steeda Performance Dampers
  • Installation Labour
  • Four Wheel Geometry

*Steeda Performance Springs Are Recommended with these upgrades

Chassis Stage 6

Excessive bump steer undermines control by letting the suspension dictate direction. Steeda’s Bump Steer Kit adjusts precisely, minimizing this issue for improved handling. Paired with Steeda’s front control arms, they are vital for lowered S550 Mustangs. Correcting the roll centre enhances steering response, reduces body roll, and amplifies grip.

Package Included:

  • Steeda Performance Roll Centre Correction Arms (Lateral And Tension Links)
  • Steeda Bump Steer Kit
  • Steeda Rear Billett Shock Mount
  • Installation Labour
  • Four-Wheel Geometry Setup

*Options available are spherical bearing or bushing; spherical bearings are recommended for track-orientated applications. The bushing is recommended for street use.

BMR suspension are no stranger to muscle car suspension upgrades. BMR have an entire range of suspension and chassis components available to the S550 Mustang, but their experience comes from taming the suspension of almost all GM’s range of Muscle cars over the years. This means you can trust in BMR to get it right with your S550 pre-facelift Mustang.
