Quick Facts

  • This is the first step you should take to improve performance
  • Allows your suspension to function properly
  • Decreases frame twist under acceleration

79 to 04 Mustangs have a notoriously weak chassis.  Take a close look at a Mustang that has been run hard.  The doors may not close right, convertible tops do not line up and the alignment shop has trouble getting the car to drive straight.  Road race and auto cross cars can actually get shorter from hard braking.   If you want your car to remain rattle free, strong and you want to get the most out of other chassis and engine modifications, you have to connect the frame sections with something beefier than sheet metal.  Sub-frame connectors are a requirement.  They are also inexpensive. 

All our frame kits are strong but designed to keep weigh to a minimum while adding the greatest torsional rigidity and structural integrity for safety.  We have been thanked by several drivers that have experienced serious crashes in both street and track GR40 mustangs equipped with our frame kits. All of them commented on how the drivers compartment did not crush around their feet due to the frame kit.
