Product Description

Steeda Performance
Bolt on better handling, reduced wheel hop and quality with Steeda's 2015-2018 Mustang IRS subframe support brace kit! This kit is not permanent and will stiffen up the subframe of your IRS for better handling and a more stable ride in the corners. By limiting the movement of the IRS subframe with connection points at the front as well as the lower control arm and toe link, this reduces wheel hop along with the added strength.

Steeda Quality
This kit is constructed of high quality 4130 chrome moly steel for strength and durability. This high quality steel is the powder coated in a silver metal flake that will look great under your Mustang. These quality materials have a lifetime warranty for peace of mind.

Installation Note
- These IRS braces are not compatible with BMR jacking rail BMR-CJR001R and BMR-CJ001H.
- These are compatible with jacking rail ST-5555205.
- Will NOT work with BMR Level 2 cradle bushing lockout kits BMR-CB005B/R.

    5 Stars   Quick install, less wheel hop
    By on 4/12/2015
    Image uploaded by Ryan L. Dramatically reduced wheel hop, it's not completely gone though. The rear end of the car was also stiffened up.

    Yes, I would recommend this item to a friend!

    4 Stars   stiffened the rear end but fitment issues
    By on 8/4/2015
    At the end of the day, the product helped stiffen the rear end. This along with the bushing upgrade from steeda almost completely eliminates wheel hop. Need better tores now. The drivers side brace fit just fine however on the passengers side there were 2 issues. The threaded plate steeda gives to allow you to bolt to the subframe was stripped. I needed to retap the plate and use a larger bolt for it to fit. Then the fitment of the brace itself was off. I needed to slot the holes for the two allen headed bolts in the back in order to get it to fit properly. I like steeda and their parts but they need to check up on their quality control.

    Yes, I would recommend this item to a friend!

    5 Stars   Stiffened up the Rear End and Reduced Wheel Hop
    By on 2/29/2016
    This product delivers on its claim that it stiffens up the rear end and reduces wheel hop. The car is now more confidence inspiring and much easier to control while going through a corner. Acceleration has improved due to the reduced wheel hop and back end being more planted. Install took a little longer than expected due to the passenger side having some fitment issues. In the end though this is a great addition to any mustang!

    5 Stars   Perfect Fit! LMR.com Expert Review!
    By on 11/22/2017
    I purchased these Steeda IRS subframe support braces to further add rigidity to my 2018 Mustang GT. Installation was super easy, and these installed in no time at all.

    They did a great job in stiffening the chassis of my S550. Wheel hop is less noticeable and the car feels more "connected" than ever before!

    I would recommend these Steeda IRS subframe support braces to any 2015-2018 Mustang owner.

    By on 2/18/2017
    Tighten up the rear on my GT350. Noticed the difference right away. Much more predictable in the rear.
    No fitment issues, bolted right up. 30 minutes per side is all it took.

    Yes, I would recommend this item to a friend!
