Another 3 link question.

[Eric Howell]

Sorry guys.
I have been reading through many of the threads and links but still have a few questions. First, is there any books that have an emphasis on rear suspension with a lot of 3 link info? Maybe with some examples.
Second, Any good online calculators? I have this one http://mysite.verizon.net/triaged/4linkcalcv15html/index.html but as you can see it was made for 4 links.

Also, what is an easy to learn software? I have seen Sysprog but it would take me forever to figure that out on my own. :throw:

Thanks.

IMO, it isn't the software that's tough to learn, it's interpreting the data it spits out that can be difficult. For a newbie, I think I'd recommend Performance Trends.

I prefer WinGEO.

There is stuff out there like this. I think it is fairly straightforward. I do not know if the three link stuff is what you are after.

This book is really in depth, but worth it. A ton of good info in there:

http://www.auto-ware.com/software/rsg/rsg.htm This looks like it could be a good start, the only problem I see is no Watt's link listed.

Thank you for that link. I'm going to pick up a copy soon.

I have a 1999 S-10 that will eventually get the 406SBC I have in my garage. It would be really cool to do a 3 link at home since it will be my beater/experimental car. A never ending learning experience as well!

I had another site that had designs for about 20 various setups from IRS to 3-link. I will try to find it.

Edit: It was Susprog. I downloaded their free trial. Looks like I need to learn alot more before even trying my own design, even with computer help!!

I know what you mean about no Watts Link. Why do it if the rear end still moves laterally because the 3rd link is parallel to the axle moving in a radius.

[Eric Howell]

Don't get me wrong, a PHB is very effective but with the size tire I will use (315 or 335) the lateral movement of a PHB setup could cause rub issues.

that's the one I ended up with, no updates, its not built yet.

i'll have the rearend welded up by thanksgiving

Any decent suspension program will give you what you need to design and build it. But no matter now thoroughly you design it make sure you include additional adjustment points so you can tweak it once it`s in. Getting a solid design on paper (computer) is a great start but making it work to it`s full potential will still take a lot of test and tune with geometry,spring and bar rate tweaks. For your purposes the PHB and watts both locate the RC. You may end up changing it`s height after you drive the truck anyway so don`t agonize too much over it. A frame mounted watts is the way to go though. We`ve been doing a lot of work with 3 link and watts links the last few years and the car (truck) doesn`t always agree with what the computer and books say is best. :doh: Mark SC&C

[Eric Howell]

Thanks Mark.

I have been talking to Jim over at Fays2 about the Watt's link and will be getting the parts for that from him. It is a frame mounted prop w/ adjustments. The 3 link will also be adjustable.

[Marcus SC&C]

You`ll be really happy with Jim and the Fays2 watts. We just finished a testing regiment with a new prototype G body watts package we`ve been working on with Jim. It`s very impressive! The prototype will be going back on our Stage 2 car and the first production one will be going on our G-5/3 link car which current runs an adj. panhard bar. Next step A body watts. :) Mark SC&C

Jim is one of the nicest guys I have delt with in the auto scene. Actually it seems like most of the PT based shops are cool.
