AME Tri 4-bar vs. 3-link
 

Now that the magazine is out and they posted this on the Super Chevy site we can now post it here. We tested Matt's Camaro showing the performance differences between a 3-link and tri 4-bar. What was really exciting about the test was that we pulled 1g on the skidpad using 275 front and 295 rear BFG KDW that have a 300 wear rating.

That is a great test! And congratulations on the superb number!

Have you guys done any 1/4 mile comparisons?

What about street driving comparisons?

Does 1 stand out over the other in these scenarios?

We didn't do 1/4 mile tests as ElToro isn't really set up to do that and were more interested in the skidpad and slalom testing. Matt (Silver69Camaro) is the owner of the car and has put a lot of miles on both suspensions whild driving it on the street so he should be able to chime in on that.

I know one of his biggest complaints with the 3-link was the noise the spherical rod ends transmitted into the cabin of the car. We have sourced a new rod end that should cure this issue though......

Rough day at work.......damn, I'm jealous.

Good video, already have and will buy Morrison products in the future.:cool:

Now everbody is confussed again.Thanks.:lol:

Craig -- You're daddy is just so much better looking than you!

:rofl:

Great video and very interesting!

Seems you can't go wrong with either solution...

See ya down at the shop buddy... :cheers: :woot:

Awesome video and comparison. It goes back to what I've been saying since El Toro. The driver matters more than ANYTHING else. If you have reasonably compliant chassis.

Awesome comparison! I guess its up to what you prefer. But pulling 1G makes it all worth it. It would be interesting to see a comparison between stock leafsprings to a performance leaf spring kit and to a 3 to 4 link kit.

Awesome real world back to back testing! I kne we made the right decision.

That'd have to include a ride-quality test as well. Link type suspensions really shine in that area.

Care to say who is the maker of the new rod ends?

We have them on the shelf and they are the same width as our Poly bushed rod end. :unibrow: Depending on what sort of brackets you have, the new rod ends may or may not be a direct drop in. Some dremel work may be needed.

For the life of me I couldn't find a 4-link setup on your website offered for sale

If you download the catalog from their website the Camaro rear clips are in there.

tried, no workie

4 Link Angles
 

Can you please tell us what the angles are of upper and lower control arms in the 4-link?

Are you guys asking about a four link or triangulated 4-bar? Are you doing an install on a stock chassis / unibody or building your own thing? Or are you just looking for the optimum angles and trying to get close?

Both suspensions feel pretty much the same on the street. If anything, the 3-link may have a tad more foward bite due to a slightly shorter IC. The 3-link feels razor sharp when using spherical rod ends though - but very very noisy.

Performance and packaging combined, the triangulated 4-bar really shines.

I finally got the catalog downloaded,for some reason it didn't want to work on my wife's laptop,

I have a question for you guys, why is it that only one end of the links has adjustable end? Why not both ends? Is it to keep the costs down? I'm on a fence ,hesitant to pull the trigger and can't decide if I should build my own tri 4-link with currie end or buy yours,the only problem I see ,is that I want fully adjustable ends, so if I have to tweak something ,I won't have to pull the arms out of brackets to do a simple adjustment,is there an option for both ends of the bar to be adjustable?Can any of you give me a good answer, Matt, Craig?

Also a quick question, your tri 4-bar kit, is it universal or made for 1st gen F body?

Thanks alot

Typically we offer four-bar/link type suspensions with one fixed bushing because they are more sucesptable to a jam nut backing off while the axle housing articulates. Granted, this usually only occurs in drag-race four-link suspensions. It's also cheaper for the customer to have one fixed end on each link.

I don't see any reason why we couldn't do it with LH/RH threaded links, but it may cost a bit more (more rod ends, custom links, blah blah). I can look into it if you'd like.

The tri 4-bar kit is strictly universal.

I'm building my own Tri-4 for my 69 Camaro 12 bolt and will use your kit if it will work for me. Going to cut into the floor a little bit for the upper links to help the geometry. Optimum angles and link lengths would be great to know.

How well does the 3 link handle 1/4 mile abuse?

Eric,
Sorry for the late reply (I'm not on here too often), but the lower bar should be at 0 degrees, while the upper is 4 to six degrees down. You'll probably find that packaging restraints will determine where it will be.

It depends on tires, basically. I wouldn't use it with some 31x18.50's, but should be just fine with street-sized drag radials, provided you aren't running 8's in the 1/4 mile.
