suspension travel

[jlude90]

is there any way to figure out realisticly(sp?) how much my suspension will travel in hard cornering and decent bumps?

i'm on H&R race for the 1990 Honda Prelude, but they're progressive, so i'm sure that would complicate it, but does anyone know if i can see how much, either mathematically or mechanichally(sp?)

for instance, if i jacked up the left side of the car, would the right side pretty much not go any lower then that?

i'm trying to figure out if i can run wider tires on this drop, and i think it'll be close, but i just don't know, did any of this make sense?

There issss a dyno to measure spring rates, weisghts, travel etc.

Being that you may be riding on oem shocks this may determine whether your car will lean or pitch certain ways in everyday driving. Try to get a sus guru to help you with that stuff though :mullet:

i'm on tokico blues, but i'm just wondering how much it would realistically move

If you didn't get it measured yet, bring it by. I have something we can put on there, that will tell you how much the suspension will move.-Bob

i have to do some figuring first, i want to try and fit 225s, but for some reason one side sits at least a quarter to a 1/2 inch lower then the other, and that'll make a BIG difference it seems

There's more to it, but if your car is able to achieve 1G of cornering force, the outside will compress with 50% additional "weight" on it.

Ex: if you have a 2000lb civic that maintains 1.0 G of cornering force, the suspension will compress the equivalent of 3000 lbs of weight on the outside on level ground.

[jlude90]

does it go up in a straight line for higher or down for lower Gs, or is it an exponential type of deal, like, a 2000 lb car with .5G would be 2500, or 1.5 be 3500?

and is there any realistic way of testing that?

It would be prohibitively difficult to do it on paper, without a CAD program.

It isn't purely linear, exponential, or anything of the sort. If you could make a formula, it would probably have dozens of terms, including trig functions.

Depending on the cars roll stiffness, and how many gees of lateral acceleration you are working with, you could reasonably approximate it, but even that would be long and arduous, and most importantly, annoying.
