First off neons are designed to handle much better than anybody is giving credit here. Remember the 2gn was still intended to be a force in SSC it never was but for a car with nearly 500lbs on any other car in the field did very well.

I had an elaborate rant here but I have no numbers prepared (the fact that I havent measured this shows how insigifcant it is to our cars)

OP search BYR's ghetto handling pack and sort of do that its exactly what you are asking for

Yeah, I already mentioned that.

As for the snap oversteer, I'm not there in my driving skills and I know I still have some things I want to get for my car before I start heading in that direction: mainly new rims and tires going for wider and a slightly larger profile. As for now I'm quite content with neutral leaning towards understeer.

DID SOMEONE SAY UNDERSTEER?!?!?!!
put your flame suit on now!

...but really... i have no idea what's going on in this thread and now i'm worried that when i buy coilovers (this spring/summer) that i'll mess up the vortex center or whatever the hell it is.

I've heard that if you are lowered it's harder/impossible to get your car on a normal machine to get an alignment. My plan is to install coilovers out of the box (i'm not sure what kind of drop that is) then take it to get an alignment. Then slam it.

would that mess up the aspect ratio or whatever?

it would be pointless because you would need another alignment after you slam it, and right out of the box they aren't really set up for your car. (mine weren't)

They'd have to put planks down on those with lifts. Those that have a pit should have no problem with doing alignments. And as just stated, once you lower it the alignment would need to be done again. You don't need to worry about the "moment center" of the vehicle if you plan on modifying the suspension and setup. do your research if you are really worried about how your car is to be setup and determine what will work for you.

I thought the discussion was over... This is what I would do if I had coilovers:

Measure the ride height before I put them on at all four corners. Then I'd slap those bad boys on and measure the ride height at all 4 corners again. I'd lower it maybe a 1/2 inch from stock all the way around. Then I'd drive like hell over to the alignment shop (for fun) and have them align it. Over time I'd pay attention to tire wear inside to outside and adjust camber accordingly. Tire size is the biggest variable with the camber settings (most likely).

Then adjust bump/rebound to how it feels to your ass.

Don't worry about the vortex center.

I think you think too much about the wrong things...

I think what I've posted just above is spot on with what needs to be done. No overthinking there. How else could you underthink that?

While you understand what changes occur in the suspension, I don't think you have any sense of magnitude here. For a 1/2" drop I would not only not rush out for an alignment, I wouldn't even take it in as any changes at that level would be so minute it's worthless and probably would be below the reading error of the alignment tools. To wit, the car drops more when 4 people sit in it than a 1/2" drop all around. Really the only parameter that significantly changes for typical drops on this car is toe on the front. Beyond that not much happens unless you slot the struts for camber, and caster is for most purposes not adjustable.

For anything up to a 1.5" to 1.75" drop on this car I would say you're pretty good just to bolt on a suspension and get an alignment in the near future. It's not until you start going beyond that mark where the geometry and the effects you describe start getting messy.
