Suspension tuning

[DriftSpecial180]

Sport compact car did an awesome set of articles regarding suspension dynamics. perhaps you can search they website, they had a lot of good info and setup suggestions.


Here i found it but its only part 1 of like 3 or 4:

I hope the other articles are better than that, I didn't really like how some of the info was put and is far from in depth.

"Anti-roll bars don't affect the ride as much as stiffer springs and have no effect on dive or squat."

First of all the terminology is getting mixed up, ride is dive and squat, when both front or rear wheels move up or down together. Second, ARB's can affect the "ride" (roll would be the term they are looking for) just as much or more so than the springs depending on the design (otherwise torsion bar suspension's would never work).

More than just this bothered me... If you think I'm being nit picky I am. This is the reason I started PdV Motorsports, so my partner and I can help people that really do care about a proper setup but aren't sure what to do and only have crap like that article to help them out.

Maybe the other articles cleared things up better, I don't know...

I don't think you're nit picking, i think you're misunderstanding it, or perhaps misreading it. I understand it and it makes perfect sense.

The reason they don't affect ride as much is because spring can help minimize roll (lateral forces), dive, and squat (both longitudinal forces). Anti-Roll bars only assist lateral forces. So yes, they are correct.

All that other junk you're talking about makes no sense to me what so ever. you're throwing in ride for roll, tomato for potato, carmen for pamela...

You're doing the same thing as the article. You first state that ARB's don't affect ride as much and then go on to say they only counteract lateral forces. The point I was trying to make is these are two different things, ride quality (a soft compliant setup) and ride (when both front or rear wheels move up or down together).

"you're throwing in ride for roll"
No, I'm using the actual term that anti roll bars are used for.

If you honestly think that is a comprehensive article then you had better pick up a real book and start reading. I'm not getting into this with you anymore than I already did, you're trying to make it seem like I don't understand and I'm just trying to clear up terminology and let people like you know there is way more to suspension kinematics than this article leads inexperienced people to believe. Otherwise the author and every reader would be jockeying for a spot on an F1 suspension team.
