Product Description

All In One Kit
If you want to give your 2015-2018 Mustang Ecoboost or GT an all in one suspension upgrade, check out this Steeda Performance Suspension Package. This kit includes the basic upgrades needed to have your S550 handling, cornering, and performing better than ever! It includes a strut tower brace, Extreme G-Trac K-Member Brace, IRS Subframe Bushing Support System and IRS Subframe Alignment Kit.

Steeda Strut Tower Brace
This Steeda strut tower brace helps give your S550 better chassis stiffness, traction, ride comfort, and vehicle handling. Installing on your Mustang's strut towers, this bar ties together your chassis while giving your engine bay a great new look. This strut tower brace is made from high strength chrome-moly steel to give you a high quality suspension upgrade for your S550 Mustang. Made in the USA, this brace features a powder coated finish and a STEEDA logo plaque to add a custom look under your hood. Easy, bolt on installation!

Steeda IRS Subframe Alignment Bushings
From the factory, your Mustang's subframe mounting holes are very large compared to the mounting bolts. This difference can make your sub-frame mis-aligned up to 1/2" left or right! Steeda has designed these high quality sleeves to alleviate this problem. These sleeves are constructed from CNC machined delrin to avoid mating two dissimilar metals next to each other. This prevents corrosion as well as reduces weight compared to other metal sleeves and the delrin material prevents any increase in NVH. These sleeves simply slide in to the subframe mounting holes and fills the extra space between the mount and the bolt. An alignment will be needed afterwards.

Steeda IRS Subframe Bushing Support System
Ready to eliminate wheel hop and take your Ford Mustang to the track to see what numbers it will run? First thing you should do is upgrade to this Steeda IRS Subfram bushing support system. This Steeda S550 Mustang IRS Subframe Bushing Support System for your Mustang GT, EcoBoost and V6 are made from CNC machined, 6061 aluminum. The steeda kit gives the rear end a much more solid feel with no increase in NVH at all.
