The more performance improvements you do to the vehicle, the more demands are put on the uni-body. Subframe connectors provide resistance to chassis flex and therefore increase the integrity and rigidity of the chassis. Installing them will also help reduce rattles and squeaks from the car flexing over rough roads. They are a must for any performance application and work well in a street, road race, or drag race application. Subframe connectors are needed if using a roll bar or roll cage to tie everything together. Subframe connectors are powder-coated black and come with complete instructions. Additional gussets and hardware are also supplied with certain models. Rocker rail and jacking rails come bare steel.

Competition subframes are required if you are going to do any racing. These are also a must for convertibles on the street. All Ford competition subframe connectors are weld-on only. Tube diameter is 1-5/8'' with 0.125'' wall DOM tubing.
