  2. Stifflers 99-04 Mustang Spider Brace
    $234.95

    Don't suffer any longer with limp front frame rails, put the Spider to work for you and GET STIFF!

    Finally ... a way to stiffen your front frame rails without installing a 12pt-cage or converting to a tube chassis! This one-of-a-kind brace works with our Lower Chassis brace to completely integrate the K-member and subframe system, eliminating unwanted movement of the front frame rails caused by launching, cornering and braking. This patent pending system acts as a lower frame rail to greatly increase front end rigidity and transfers suspension loads to the strongest part of the car, the subframe system.

    - Dramatically increases front end rigidity by acting as a lower front frame rail.
    - Eliminates unwanted movement of the front frame rails.
    - Transfers front suspension loads to the subframe system.
    - Improves braking performance.
    - Decreases weight transfer response time.
