Trying to get all I will need to install an 8.8 rear and a 4 link suspension.
What will I need. I've seen some 4 link kits on eBay. Will i need coil overs?
Anything else. I know I will have to weld the mini 4 link onto the 8.8. So I won't need a torque arm because I will have a 4 link correct??

Any and all positive comments will be appreciated.
Thanks.....

Post a link of the kit you are looking at (if its allowed) No torque arm, the 4 link will locate your axle front to back (plus pinion angle, etc) and the panhard will locate it side to side if what I am seeing in the kits is correct.

If you are looking at doing what they call a mini four link that attaches the "upper" control arms to the lower control arms I'd advise against it. Those that have tried it didn't like the outcome and this is why you don't see it discussed today.

If you research instant center it will explain why it doesn't work.

Here is the kit I'm looking at.

I know what I need is triangulated and not parallel.
What do y'all think go this kit?

Won-Ton

From the look of that kit it will make things worse.

Too much or too little IC can cause a loss in traction, sometimes a great deal. It will plant the tires too firmly causing the sidewall to distort, or not firmly enough causing them to just spin. There are so many factors that can alter your desired IC that it is next to impossible to weld on a universal kit and improve your traction/handling.

Now if you get a 4 link calculator, and go through the time consuming process like I did, you can get a suspension that works better with your car, style, and power.

Long story short, there is a reason the vehicle specific, proven kits are far more money...they took the time to figure what would work.

I appreciate the reply. I'm not sure you know. There are no turnkey kits to 4 link a 4th gen fbody.

You really need something with some adjustability like this one: link


I would think MWC or some other sponsor could set you up with a kit. Obviously any 4-link on an F-body is going to require a lot of welding and fabrication.

Won-Ton

Anytime, did not know they didn't exist. And yes I agree...the slots on the brackets are great way to tune anti-squat.

What is the benefit(s) of this 8.8/4 link swap?

Hiltsy thanks
. Looks good. I wanted the triangulated so I wouldn't need to run the bar to center the rear end. But I can just add that to this kit. M

Benefits are not blowing up my 7.5 rear. I have over 500hp. And the 4 link helps you hook on launch.

Gotcha

So I realize that I'm not a pro here....how does a 4-link prevent you from blowing up your rear when compared with a properly set up TA system? And I thought you were putting in an 8.8 not slapping this on a 7.5?

Won-Ton

He is going to an 8.8

Ok sure, still doesn't answer my ? about the 4-link vs a TA setup though, especially on a car designed to have a TA.

I mean this dude seems to do alright with a TA: Pretty fast 6-speed f-body

EDIT: Don't you also have to give up your PHB for this?

Won-Ton

The increase in axle size is to help no blow up the rear end....the 4 link is to help with the launches.

Ideally a triangulated 4 link will eliminate the panhard

I don't think I've ever heard of an F-body that had a bad 60ft time as a result of the TA though. I'm not saying that a 100% dialed in 4-link wouldn't be competitive, but based on ebay parts and an 8.8 it doesn't seem like that's what's happening here.

My vote would be to stick with a TA setup, and look into a used 9" or 12-bolt. I'll be quiet now.

Won-Ton

I gotta agree, doing a 4 link is a lot of work to make it work properly...especially on a unibody.

There is also a reason that a lot of mustang guys move towards a TA PHB config.

I'm not sure I'd say that. I personally don't know any Mustang that has moved to a torque arm for drag racing or road racing. Now I've seen Mustang chassis converted to a ladder bar and some do confuse that for a torque arm.

Yes people have done it but it isn't very common especially for drag racing. It is hard to out do a four link suspension.

Here is a thread on a mustang forum: http://www.mustangevolution.com/forum/f280/t352032/

And there are at least 3 companies (I won't link since they aren't sponsors) that make the kits. I'd say that's pretty common.
