I understand about roll axis On roll centers, how do you know where to set it ? What I mean, if I'm building a new car, how do i know where to start?

I looked for your debate on roll centers and couldn't find it.

If you understand what I am asking then which do you prefer ? If you are seeking roll center knowledge start your own thread with the question !

Teeter toter

It depends on the track, rough or slick! Slick track rf in the dirt and the left rear 4 foot of split in the fender well LOL !!!!!!!!!!!!

On a rough track RR buried in the fender well and both front wheels 4 foot off the ground wide open LOL !!!!!!!!!!!!!!!!!!!!!

Thats just what I see every week at the local tracks we race at !!!!!!!!!!!!!!!!

[1cln_sdime]

I agree with that to a point on a rough track on r car we dont like a crazy amount of lift and keep all 4 on the gound, basicly a more nutral car to soak up the bumps

So how do you know where your roll center is , static or dynamic ?

I use my pull down rig.

[proped]

Roll center is the result of the motion not the cause and the geometry can only be used to point at the roll center NOT CAUSE THE MOTION. I know what it does and what it doesn't do.

People think the roll center is so important and doesn't even know what it is. Setting static roll center doesn't tell you where it's at unless you have data acquisition (or at least looked at some date) you have no idea what the car is really doing.

I think camber gain is more important, tires temps.

How do you track your migration? Since i can change control arm pickup points and lengths which move my roll center static and dynamic locations to any place i choose, and keep my camber gain a constant, and notice a significant change in handling, why is camber gain so much more important? Just asking.
