Maximum Motorsports Low Profile IRS Subframe Bolts (99-04 Cobra)

AmericanMuscle no longer carries the Maximum Motorsports Low Profile IRS Subframe Bolts (99-04 Cobra). Please check out 1999-2004 Mustang Limited Slip Differentials for an updated selection.

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.

      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.

          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.

          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

          These bolts were easy to install and the head is a lot smaller than the giant stock bolts.
