how is being lower going to "stance" you? going lower will give you even better handling. im lower than you and i barely scrape when i corner hard. all the scraping i do is because i bent stuff in the back when i first got the car so i have positive camber. i also scrape against my fender liners but there almost wore through.

also how is it not "safe"?

also my question is why in the hell would you put racelands on to race.... you would be better off on a set of agx adjustables and the eibach pro springs you had on... would have cost about the same.

Poor roll center location. The extreme lowering of the car pushes the moment center underground, creating (among other things) an extremely long moment arm which causes more roll, contrary to what you would expect from having lowered the center of gravity.

I am speaking of kinematic roll centers which are easy to understand, but an incomplete picture. If you want to know the real goings on you will have to read up on force based roll centers which generally trend in the same direction as kinematic ones given the same inputs, but are significantly more complex when it comes to precise computation.

Please note that when I quoted your post, I cut out that question. This was not accidental.

As for your brain hurting, welcome to the wonderful world of suspension tuning where the only thing you can say you know for certain is that you don't know everything.

I'm no engineer, I just play one for work. But shouldn't moment be calculated at the furthest point of the control arm from the fulcrum and not "behind" it?

In essence, at the wheel and not underground since you don't look at the movement of the control arms together as a unit, rather as independent because they act indescriminate of one another.

I am not an engineer either and don't play one at work, but here is how I understand it. For a go-kart, yes, for a suspended vehicle, no. For a suspended vehicle, we are looking at how the forces that come through the suspension impact the body (roll) not the other way around. I think (and could well be wrong) that you are looking at the other way around.

That is the reason why you cannot look at independent suspensions independently. The body is a rigid member and that is what the moment arm is being applied to. Make sense?
