Double A Arm suspension design

[rcs_888]

Hey guys,

I was wondering if there was anyone around that could point me in the right direction of either someone specific to talk to or some reading material of suspension design. I have read a couple of books like "how to make your car handle" etc but all the books i have read more lean towards bandaiding existing suspension design. Nothing i have read talks about starting with a blank canvas like i am wanting to do.

The car and intention is an R34 GTT that i have been building as a Sports Sedan, so circuit racing. With the rear end i have been trying to work with it but with all the suspension working as imaginary piviots and all the subframe piviots being off axis etc i am having a mission of a time working it all out and i think going back to basics and the old KISS principle will be beneficial to me in the end.

Bill and Doug Milliken have written the books you want to read.

The linked site has some useful info too http://www.buildyourownracecar.com/race-car-types/

To be honest suspension is best done on software - it will let you work out, for example, how much camber compensation you get in roll and a bunch of other things.  Which software to pick may be your question?

For a sugestion:
Analysis Techniques for Racecar Data Acquisition by Jorge Segers is not the worst book by any measure.  Sticking point is you need a high level logger to record data on things like damper movement etc.

Also have a look here:

Carroll Smith has some good detailed info on nearly all aspects of race cars.

I had "engineer to win" but I can't find it now. It had good info about material use in race cars as well as suspension info.

If that image is your actual car, that toe base might give me some concern.

Can think of several people who have built multiple sport sedans over the years who are usually up for a chat, without knowing where you are though, best to join the State club and someone should point you in the direction of who to consult. As mentioned though, most do it via software nowadays, even if they're more comfortable with a drawing board.
