The upper and lower control arms keep the rear axle from moving front to back.

The Watt's Link keep the rear axle from moving side to side. Without a Watt's Link or a Panhard bar, the rear of your car will wallow around over the rear axle; the only thing keeping the rear axle under the car will be when the tire hits the inside of the fender. I had a Panhard bar bracket crack with one lap to go during a road race, and the fenders held the tires under the car for that last lap. It was one wild ride.

I don't know if the Tri-Link will fit with the Watt's linkage in place; I would worry about interference. Jim Susko designed the Tri-Link to work with his Panhard bar.

The Tri-Link is built for racing, and the metal spherical rod end bearings work great for maintaining good alignment during high racing loads. Unfortunately, the metal rod end bearings transmit a lot of noise, so now you will hear clanks and clunks from the linkage - not a good thing for a daily driver street car. I have won many road races with the G-Force Tri-Link and Panhard bar on my race RX-7, but when I built another street RX-7 a few years back, I use stock Mazda rear axle control arms and Watt's link on it, just for comfort and quietness.

No.

You need to properly repair the upper link mounts.

If you are dead set on a third link you will also need a pan hard.

The third link goes right where the upper link on the watts is, so no it won't work. I haven't driven with my setup yet, but as said above its noisy as hell.... should be worth it though.

An no, it would not be safe to use the car with no watts link....
