I don't understand what the angled square support tubing is for. How would it mount up?

That angle iron welds to the frame for support. It is mandatory. It is support for the front of the 3rd link. In the picture it mounts to the left end of the 3rd link. Run a bolt thru the angle iron, thru the heim joint.
Now for the right end of the tri-link. The small bracket welds to top of the diff pumpkin. Bolt goes thru bracket and thru the right heim joint on the tri-link.
This tri-link is SCCA ITA and EP legal. In those classes you cannot mount suspension pickup points inside the car. Thus the bent 3rd link that goes under the tranny tunnel and the odd angle bar mount that mounts *under* the car. A much more effecient way to build a tri-link is to make that link straight and run thru the floor and mount inside the car to the crossmember behind the seats. Been there, doing that.
ISC does have some very good products and I have reccomended them to several people. Mike has put a lot of time into developing them and testing on the track. I personally preferred my design of a tri-link and went in that direction.

Yea Mike has some nice stuff. IMO its a bit over built. Ive been to his shop and seen all the toys. I think J. Suskos tri link is a better engineered piece. Thats what I run on my racecar.

Oh and Brad is right. If your not rules limited, the straight bar is better. Mazdatrix used to offer this as a kit years ago. Dunno if they still do.

FWIW Mazdatrix hasn't sold their tri-link for years.
i use the isc rear threaded spring adjusters and they make raising and lowering the car and cornerweighting immensively easy. highly reccomended.
here's pics of my tri-link. a real nice piece of custom work. fully adjustable in every way. cost $390.00 installed.

Could someone please explain the tri-link to me?
I dont understand how that single bar keeps the rear axle in place laterally..is it just rubbing on that metal piece on the body???

Chemical, the 3rd link doesnt replace the watts link. The watts link is still what locates the axle laterally. What the 3rd link does is replace the 2 short upper links, which removes most of the binding in the rear suspension during roll. This makes the car less tail happy.

Got Boost?
Cool, I finally understand what the third link really is.
Brad, you had it made custom, or did you make it your self. I'm just wondering where you got all the stuff to make it, and if its somthing that could be reproduced easily

custom made by www.sevensonly.com they went to a stock car race shop and bought the link, heims, and brackets, made some changes to the brackets and installed.
it can be reproduced easily with welding and fabrication skills of course.
the link shaft itself is 19" long not including heim joints.
be sure to use big wide brackets everywhere so it'll spread the load over a wide area.
