Suspension Tutorial
 

Hi,

I'm reading all sorts of good info on suspension stuff like bushing replacement, torsion bar sizing, etc. I realized that without a real good look and ability to tinker under the front of the car I'm missing out a bit on the fundamentals of the porsche suspension setup.

First I'd like to focus on how the front really works, and make sure I understand the correct nomenclature for each component.

Can anybody recommend a good place on the web with sort of a tutorial and explanation on how the P car suspension works? Pictures or diagrams to go along with the text would be great.

Thanks

Yoy could use the search "suspension","A arms" "trailing arms" "ride height" on this site, or the rennlist site. Buy the Bentley, Hanes manuals for pics or other books sold here on the Pelican site. That will give you plenty of info till your ready to work on yours.

As Rick said, the Bentley is a good place to start & a must buy. Some excerpts below. I am also in a learning phase.

Have you looked at Pelican's tech articles? Look in the 914 section as well for "5 lug upgrade." Since they use the 911 front end, a lot of explanation is there.

Also, check out Elephant Racing on the web. There is some flawless reasoning there. There are tech articles on Rennlist as well.

Some of the info in this thread including the scans may help.

Depends on what you mean by really works.... I'd get a simple text or primer on autmotive suspensions and look thru that. Also, there are some old R&T and C&D articles on this. Then you could move to Race Car Vehicle Dynamics to get really deep into it.

Remember, a suspension is designed to keep the tires on the ground while the car corners and goes over bumps, and etc. There are design constraints such as space and costs. Space affected the suspension choces on the 911. Double wishbones would be better but then there is no trunk.
