I need to find out some information for someone I know as well as myself. This person I know has a 2001 mustang (bullitt) the car has factory bolt in subframe connectors. He is wanting to add a torque arm suspension to his car and run in ESP. The type of torque arm he is wanting to use is made by maximum motorsports http://maximummotorsports.com/panha...talled.asp which uses a member that ties the two subframes connectors together which I read the rules for SM doesn't allow for lateral connection between the connectors or am I mistaken, can be allowed to add the torque arm in these two classes? Can you please clarify this issue.
