3 link suspension

Looks like I'm gonna have to talk to you at the show. I just have to find you now.

Starting at the ATS booth, walk out, hang a right , go to the end of the isle, hang another right down the next isle, and look about 3 booths up on the left side, and you'll find Lateral Dynamics.
We will be torrmenting them with ATS paper air planes the entire show.

Mark-
Killer setup. I wish I hadn't already done the T56 transaxle in 50/50, or it would have gotten your 3 link.

Might I suggest



'80s babes not required, but would be a nice touch

Or perhaps one of these: The AirZooka

Am I the only one that thinks this thing is a bit over designed? What is the wall thickness of that mess of tubes on the axle?

I am going to go out on a limb and ASSume you some sort of clue as to what you are looking at. You do do realize that this arrangement includes a frame mounted Watts link and the bracing nesessary for that and the bellcrank correct? Yes, running a Watts link and frame mounted vs. rear housing mounted is overkill but might as well go big. The frame mounted Watts link requires a great deal of trial and error to get it right, I can tell you Mark has been working on this for over a year (everyday) and is fanatical about things being done right.

Pretty bold post for one of your first, how about sharing some of your background for making such a statement since we haven't gotten to know you yet. (This is a pretty tight community and Mark is well known as a expert in his feild).

First, what do all the tubes on the axle have to do with a frame mounted watts link? The only thing that connects to the axle are the links?

Second, are you telling me this design was accomplished through trial and error? Shouldn't it have been designed by engineering principles.

It just seems like there is a bunch of unsprung weight on that axle.

Hmmm...my background...Internet poster. What is the background of Mark. I would assume he is a suspension engineer or has a great deal of race experience. Maybe we should be concerned about his background.

The question was intentionally open ended. I want justification for all the tubing on the rear axle. I am not making it, I am buying it, so I want to have some level of confidence that I am buying something from a qualified company.

OK, so you don’t like my vague questions. So, I will ask engineering questions. Then I can do the math to see if this is something I need.

1. Was this designed for a range of ride heights? If so, what is the range and the Jounce and Rebound levels for each ride height.
2. It looks like the tubes for the watts link hang below the diff. How far below, and what is the ground clearance at curb and full jounce?
3. What is the rear roll steer % at each curb height?
4. What is the range of anti squat and anti lift %?
5. What CG height are you assuming?
6. I know you need to remove a portion of the tunnel, do you need to remove any of the floor or trunk to accommodate the rear mount for the three link. It seems like it would limit jounce travel.
7. How long are the links for the watts link? What about the length of the bell crank?
8. What are the tube diameters and wall thicknesses for this setup?
9. What is the weight of the whole system and how much of that is unsprung?

There a few questions to ponder. I assume at the very least Mark is an ME.

Mark and his partner Katz are both experts in this field. Trust me I know first had had from working directly with Katz he cuts weight wherever it is possible he is concerned with performance first and looks secondary when it comes to this type of stuff. I suggest you read this from the begging before making random assumptions form the viewing of only a few pictures.

What Are your engineering credentials?

And buy the way this was designed "by engineering principals." but this is not a exact science and still takes a long period of trial and error to find the just the right amount of compromise to build a well balanced and functional system.
