  1. Stifflers 96-04 Mustang Lower Chassis Brace
    $119.95

    Stifflers' lower chassis brace dramatically increases the strength and stiffness of the front chassis area and factory K-member.

    This additional stiffness helps to maintain correct front suspension geometry while under load by minimizing flexing. The result is tighter steering response and more predictable handling under cornering and braking.

    - Manufactured of 1 x .083 tubing to maximize stiffness and strength while reducing weight.
    - Design optimized using CAD/CAE software combined with real-world test data.
    - Industrial grade powder coat for long life, to outlast the vehicle.

    Combine with our Spider Brace to completely integrate the front and rear chassis sections for unprecedented car control!

  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.
    - Improves steering stability and predictability.
    - Four wheel alignment (front-to-rear) remains consistent.
    - Reduces interior vibration and noise.
    - Can be used alone or with Stifflers Fully Integrated Technology (FIT)System.
