    Product Information

    Features, Description, Reviews, Q&A, Specs & Installation


    • Adds Tire Clearance.
    • Run Wider Tires.
    • Bolt-In Installation.
    • Sold as a Set of Two.
    • Fits 99-04 Cobra with IRS.


    Go Wide. Your Cobra's IRS can prevent you from running the width tire you need to get the traction you need. But with a pair of Maximum Motorsports Low Profile Subframe Bolts, you can ditch those wimpy narrow rims and go wide for better launches and more aggressive looks.

    Perfect Fit. Maximum Motorsport's Low Profile IRS Subframe Bolts replace the OE bolt with its .5" head with a .35" low-profile bolt and washer. And unlike the factory bolts, they have rounded edges so if they do make contact with your tire they won't damage it.

    Bolt-In Installation. These bolts are a direct replacement for your OE subframe bolts, making installation straightforward and hassle-free.

    Application. These subframe bolts are designed for the 1999 to 2004 Mustang Cobra with IRS (independent rear suspension). Sold as a set of two.

      Maximum Motorsports low profile bolts

      Installed these on my car to gain clearance for a 315 tire. Worked perfect, no issues and offered a lot of extra room for tire clearance.

      Great bolt for large tire clearance at IRS.

      Purchased these boots because 315 series tires on 10.5" rim needed more clearance than the large hex head bolt on IRS would allow.

    1 Top Rated Question

    Is there just one of these bolts per side on the rear? Since they are sold as a pair I assume you only need 1 set to eliminate the clearance issue when running wider tires?

    • One per side, cheap insurance if your running 315's or wider tires.
