I see that they are sold to fit the 05-09 cars but never see anyone recommend adding them. Are they needed or are they a thing of the past?
The key is welding them in and welding them in properly.I have been putting on sub-frame connectors on all my Mustang's; Fox, SN95 and S197. Any car that is unibody benefits from having its chassis connected. I run my cars hard and most make decent power, so having the frame rails tie together (welded) is a big plus for me. They track straight, alignment is perfect and launch properly. Obviously, suspension has a lot to do with it too...
For a couple of hundred bucks, you get extra ridged (especially if you own a convertible) and less chance of distorting the frame, wrinkling the floor pan or pulling out a control arm from torque box. Also, might aid in a collision...
Either way, opinions are like... LOL
