Hey all. Looking to reduce the periods of understeer that my car goes through when taking turns tightly, and sometimes not even that tightly at all. Mosty in wet weather, but where I live thats most the time anyway. I have a farely stock 95 gt, only mods in question currently are Megan springs and stag struts on it.

I did a tad bit of searching the forums and found some info, and I was hoping to get some clarification and maybe some advice.
Will these modifications/addtions help me in this quest?

lower front end
Front strut tower bar
F&R sway bar

Is there anything else that can help? Will a strut tower bar/thicker sway bars really help?

At the moment my car has rear bar disconnected. Noticed slightly better turn in with no added body roll. Thicker front bar on your car will help with understeer.

What? Stiffening the front end increases understeer. Understeer is when you can see whats about to kill you. Oversteer is when you can't see it because you're going backwards.

Stiffer rear end results in less understeer from my test results. I've played with bars, bushings, suspension settings, and tires. Even with grippy tires, the front tries to go straight under lots of pressure. How I remedied my issue was by putting the ST205 rear strut bar (top mount) in, energy suspension rear sway bar urethane bushings, MOOG sway bar links in the rear, and coilovers with a heavy spring rate and a mid setting (18 out of 32) for dampening. My rear also sits slightly higher than my front end.

Car actually oversteers into corners at high speeds now with my winter tires on lol. No hand brake needed.
