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.


  • Requires a Stifflers' Lower Chassis Brace  for installation
