Hi everyone, we have undertaken a project to finish a 1st gen that a friend has started but boit had the time to finish. We currently race a 2nd gen and are quite competitive in our classes. My question is does anyone have any drawing or pictures of a good 3link set up for a 1st gen? We ARE able to cut the floor etc, so any help would be greatly appreciated. To see both cars you can go to my website. www.abrracing.com

 

Just go to ISC Racing and get theirs, save yourself a bunch of trouble.

 

Or go to: http://www.gforceengineering.net/ for Jim Susko’s tri link. We make a lot of our own stuff but this is one part we always buy.

 

Since you are able to cut the floor then take a look at what was done in this link. Might help you if you want to do the work yourself. Peejay is a forum member here.

Gforce sets the standard for first gen tri links. Jim is very helpful, and always reachable by phone.

 

Here is mine:

 

Mine had significantly more antisquat than that (my front pivot was in about the same spot but lower, the rear pivot was much, much higher - at full compression the top of the mount was about 4" above the trunk floor level) and I also ended up bracing the front turret against the trunk floor with angle iron.

On the new car, I'm just going to copy the method used by Ford for putting a 4 link in the Escort. TTE did the same thing for their Group B Celicas.... it's just a couple walls of 16 gauge and a top cap also of 16 gauge, and doubled thickness at the mounting location.

 

I just installed the gforce unit, when to a wet autox, and it worked great! extremely controllable oversteer (instead of the tank slappers I use to get). keep in mind this is with v710 through water puddles, can't wait for a dry event...

 

I know this is a dumb question but I have to ask. Would you use this 3 link in combination with a panhard bar? I am really going to invest in a 3 link bar for my RX-7 now. The pics helped clarify things for me.

 

Yes, you would ideally use this in conjunction with a panhard. The three link and panhard will replace the watts links as well as the upper trailing links.

 

I found that when the roll center is out of plane with the lower links, you get some wild rear steer characteristics. Feels really funky on lump pavement.

The stock 4 link is restrictive in motion enough that it doesn't do that. Let it move, and it moves all right

So, I now consider a Panhard to be almost mandatory.

 

G-Force Tri-link + panhard bar = race winning rear suspension
