what does corner weighing represent , do you want to preload so weight is evenly distributed? is it a weight transfer thing or a ride quality thing? im tring to undertand preloading more if anyone can break it down for me that would be awsome!

seriously......

 

Took me quite some time to figure out preloading by reading Google searches, although it did help.
Maybe if you know something about them, you could give a quick and dirty rundown of it.

 

Corner weighting doesn't have much to do with preload.

I'm wondering how you can have 10k posts and not understand basic suspension theory.

maybe he isn't really into his suspension 'til now. I would also like to know the same thing he does.

 

Depending on what type of coilovers you use, preloading and cornerweighting can be related.
On coilovers that do not have independent height and preload adjustments, adjusting the preload will also affect ride height. Ideally, you adjust the spring perches on your coilovers to increase or decrease the weight for the specific corner you're working on. However, without individual height and preload adjustment, then you won't be able to do one without changing the other. Its tremendously difficult to cornerweight a car with this type of height/preload adjustment. So, you end up messing up your preload in the process of cornerweighting.
Anyhow, I'll respond to the first poster as best I can: the purpose of cornerweighting is to provide even weight distribution through corners, like you said. Its not necessarily having the same weight at the two front wheels, and the same weight at the two rear wheels, because obviously "unadjustable" weight of the car (the stuff between your four wheels) isn't going to be equally distributed. In any case, you do various calculations to get to your four ideal corner weights, and achieve those by properly adjusting your coilovers. Like I said though, you can't do so without messing up your preload settings unless you have a set of coilovers without independent height and preload adjustments.
I did my best to cover preloading in another post, but the basic idea behind preloading is to allow your coilovers springs to perform at a stiffer spring rate, eg. 600lb springs instead of 450lb. Its done by compressing the springs before they are installed onto the car (hence pre loading them). Then, when they are put onto the car, it takes more initial force to compress the springs, and they will expand with more force as well, just like stiffer springs would.
