    Features & Details

    • 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.

    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.

      Never installed but they look pretty? Lol

      I can't say for 315 tires, but I have 305's on 18x11" wheels. I bought them because they were cheap but never installed them. My aftermarket wheels have a 10mm offset while most 10.5" width mustang replica wheels are at least 20mm usually 24. I rolled my fenders, and the 10mm offset is such a perfect stance with no rubbing on the fenders or factory bolts. My wheels tuck perfectly inside the fenders and look absolutely unbelievable with no spacers or other mods for clearance. The CCW fitment for 99-04 cobras or irs swaps seems to be about a 16 so I'd be curious if the 6mm makes a different on inside clearance if anyone knows...

      Amazing fit and finish

      These bolts fit perfect and allowed me to run that awesome 335/30/18 rear tire!! The look is out of this work without worrying about destroying the sidewalk of my tires with the old bolts

      Good Quality Easy

      This is a great product and very simple install for anyone with a jack and a few stands. Total installation from beginning to end is expected to be roughly an hour.

      IRS Subframe Bolts 99 Cobra

      The IRS subframe bolts were a lifesaver! Installation took me about 30 minutes with a floor jack a pair of jack stands. Just follow the simple instructions that come with them. A tip I'd pass along: only about the last 1/4 of the bolt is actually going into threads. So if you have the bolt only halfway in/out and it's a tough go, the holes aren't properly aligned. Use the floor jack as shown in the instructions. Helped me fit my new 315s!

      IRS bolts

      They work great, if your tires rub these then something is wrong. Only 4 out of 5 though because of strong warnings in instructions about how careful you have to be with your tightening methods so you won't strip out the Allen head so I'm guessing they aren't grade 8
