We have created a weld in gusset kit that addresses all of the weak areas that we've found from building race cars over the years.  Everything is 100% chromoly and we do suggest tig welding in the gussets.  The tubes that span from front to back are not included do to chassis variations and normal damage that we see on a regular basis.  We will go over any questions regarding placement or modifcations that you may need to do over the phone.
