So whats up with my handling?

you can read my mods in the sig...
but i noticed that if i go into a turn or the twisty's ...i can feel the front end dip and the rear wants to come around. pretty dangerous if you ask me. no Im not trying to push the car past its limits in speed as i enter the turn.....
On/off ramps and pretty hairy!
I think its called over steer? or is it under? LOL i dunno. just seems like im constantly wandering all over the road and the turns just make it worst.
but what can i do to fix this issue?
I thought lowering and Bilsteins would give a better handling?

If you added rear sway bar diameter without adding front, the car can increase oversteer tendency. Also with relocation brackets, as you enter a corner, the outside wheelbase increases and inside wheelbase decreases and can contribute to roll oversteer.
A quick test would be to move the LCA's up a hole and see if your tendency improves. Unless you're drag racing you should be good to go in the first hole instead of the lowest.
You could also decrease rear bar size or add front bar size then check the balance.

i dont have a caliper to measure the front sway bar..but it is the thicker one. SO i put the thicker sway that came on my IROC to somewhat match.
my old TA rear sway was way smaller than the front but now they are both about the same size.
You are describing exactly what im feeling....."roll oversteer"

If you added rear bar to a balanced system the car will tend to oversteer (or understeer less, or whatever). Provided it was balanced to start with. The tendency is toward making the rear rotate more.
Are you drag racing? If not, I'd move 'em up a hole and try it.
Many drivers run relo's on the lowest hole with no oversteer tendency but corner oriented drivers sometimes prefer the higher setting due to that feeling.

I'd try the relo's up a hole and see if it suits.
If it still oversteers, then you could put the smaller bar back on or add front bar.
Adjusting the relo's would take about 10 minutes and be a good first step.
Let us know how it goes.

Yeah if your not doing drag racing, you typically want the LCA's parallel to the ground, or even angled down from axle toward chassis. Roll understeer tends to keep the car stable around corners.

For handling, you want whatever feels best for you. It's a combo of keeping your tires attached to the ground as much as possible.. being able to control the car in a slide.. etc. So it's really a personal preference thing.
Now that being said.... Here's a few ideal popular setups. 35mm front bar and a 22mm rear bar works very well all around. I've been playing around with a 35mm front and stock 19mm rear. It's worked decently for me, but I may go back to my 22mm rear again. Something a tad softer but well balanced would be the 32mm front and stock 19mm rear.
Those larger 25mm rear bars will limit your roll in the back by quite a bit. The problem is that when it breaks free, it breaks free quick and is harder to control on the edge of traction. Under certain circumstances it could cause more understeer.. other circumstances more oversteer. All in all, you are trying to balance the car so that you minimize both over and understeer. Sometimes its better to let the springs do their job. Sway isn't always a bad thing.
I am purely speaking from an "at the limit" standpoint. Street driving it's pretty tough to put your car at the limit safely. For people who just mod their car for street driving, you can pretty much do what you wish. You're not really trying to get an edge on anyone on the street anyway.

If the front bar is just a touch smaller than 1.25", then you have a 30mm sway bar.

I'm following this .... as I have pretty much all the suspension pieces that the OP has. They're all new (under 4 months old). I have the dangerous oversteer problems ... and will take the aforementioned advice of moving the LCAs to the upper hole.

if you guys really wanna see the difference take the rear bar off completely and see if that fixes the problem. Should make it want to push the nose like a dumptruck in a hairpin
