Loosing traction on corners...(98z)

What's the biggest culprit of loosing traction when taking corners? I can think maybe of the following:

shocks
springs
LCAs

Are those culprits and if so how would one rank them?

Anyway, I find that I can't be very aggressive on the throttle cornering or one of the wheels may slip. Also I changed my shocks out recently for the 'high-end' utozone garbriel shocks recently, however I think I had issue before that (yes I know they're not the best shocks). Anyway, I'd like to get this under control.

Any tips on what to look for. Oh BTW, I have poly endlinks and bushings on the rear. Everything else is stock except the rear shocks as I mentioned.

Do you have poly in the factory lower arms or is it just poly on the anti-roll bars?

Poly bushings on the swaybar and the endlinks. I think I'm replacing those with rubber (lots of squeeking in the back going over bumps slow).

As for tires I got the Firestone Firehawks...


BTW, I think I just solved the problem. I used to get my car serviced at the dealership which including checking tire pressure. About a year ago I just started going to a local oil change place. Well lo and behold, the pressure on all 4 tires were low and low by the same amount! It's rainy now so I can't test it out, but I bet that's it.

This slipped by me because I used to check the pressure all the time and it was always 30 PSI (thanks to the dealership), but stopped doing it.

Gabriels are junk, wouldn't even put those on a daily driver. I'd get Monroe's over gabriels.

How bad can they be? If they're that bad, I may go ahead and order some bilsteins or something else later on. The rear of the car doesn't bounce when I push it down so they were doing at least a good of a job as the old stock ones, so I'm in no hurry.

those tires were good when new, how old and how many miles on those firehawks?

soft springs and low tire pressure don't increase corner wheelspin. prob the LCAs or your diff is shot. what year is it again?

98, I found also found that my panhard rod had a bit of play in it and tightened the bolts after lubbing the bushings and that helped too. (as well as get rid of a bunch of noise in the rear).

The firehawks have about 30k on them. To be honest handling or traction wise, I didn't see a huge edge over the goodyears that came with the car stock, but I wanted to try them anyway a couple years back since they got such high ratings on tirerack.com.

I also found that my PHB helped 'sway out' as I call it on bumps in corners.

Firehawks are not the best tires...And as far as bilstiens go.... I have them. If I try to jounce my suspension, it's stiff as h3ll. But it rides great! w/ the Eibach springs too. (I think they're revalved SLP Eibach's)

I was going to say tire pressure, but you already nailed that one. I adjusted mine from 26psi to 28 psi and I get squirley too easily now. Especially on a 35 sidewall.

I wish I could answer your question. I can't, not given the information here. I'm completely unclear if you are getting:

Fine steady state balance, but power oversteer?
Loose in steady state cornering or not?
If fine steady state and not purely a power oversteer issue, is it bumps that cause the rear to move?
When the rear moves just it do so in a "jittery" fashion, or just slide?
When the rear moves is it because you just spun the hell of one tire (weak LSD which makes for nasty oversteer)?

All I'm saying it what you have there is like telling your doctor you're coughing. It's not enough to go on. What's worse is suspension tuning is much more complex than any other single part of the car since there is overlap (but not the same reactions) from many parts.
