  6. Maximum Motorsports 96-04 Mustang 4-Point K Member Brace - MMKB4-4
    $134.97

    Maximum Motorsports 96-04 Mustang 4-Point K Member Brace

    * The front of the MM brace mounts to the bottom of the K-member. The rearward points of the brace mount at the K-Member-to-chassis mounting points.
    * The MM K-Member Brace's design includes a structural steel web. This splits the suspension loads. Part of the load goes into the unibody at the rearward K-member to chassis mounting points, and part goes straight across the K-member to the opposite side.
    * The mounting bolts for the brace attach through a structural tube. Unlike commonly used flat tabs, the suspension loads pass into the MM brace without deflecting the mounts.
    * Note: 4-Point braces will not clear long-tube headers. MMKB2-2 will clear most long-tube headers.

  8. Steeda G-Trac Brace (1979-2004 Mustang) - 555-5500
    $69.95

    Steeda G-Trac Brace Ð79-04 except convertible, Chrome-Moly - 555-5500

    The revolutionary G-Trac bar was developed by Steeda's SCCA road race team to stiffen the Fox body K-member and maintain proper suspension geometry in max-G cornering.
