GMs in IT

[Ron Earp]

When I look at the four link in a Mustang I see the ITA/ IT7. The three link conversion on that works pretty good and has already been accepted as IT legal

Yep, and it does a damn good job on those cars and Jeff's TR8. We're designing our own with the 7.5" in the stang and we have access to some CNC milling in ally. Putting it together in CAD we can design a tri-link setup that is very light and strong, thus minimizing the weight addition. Of course the physical pad/attachment to the car is done with steel. We could do a torque arm for the 7.5" but the weight there is pretty high, even with extensive use of ally. I'm also not convinced the torque arm is ideal.

Ford's tri-link on the new stangs is light and it works well I'm told. If we could reliably weld bosses on the 7.5" cast housing it'd be ideal, but that piece wouldn't be easy to attach to after the fact.
