Car losing traction in corners

I have gotten everything calibrated and aligned to the best I can..

I am looking for a way to reduce this and have not found a solid answer to my question since there is a lot of different items out there. I was thinking about purchasing a rear sway bar in hopes it would fix it...possibly a front? idk, because im not sure if its the front or back that causes this.

Whatever it may be, if you guys do think my best bet would be to get a sway bar etc.. would i need a re alignment or what would I have to do when putting it on?

Put everything back to stock and sell your car. Thats the only solution I see here for you that doesn't result in a significant loss of money or injury.

The extra roll is probably from the lowering springs. One thing to try would be roll center adjusters, and/or raise the car back up.

What wheels did you get? are they significantly heavier than stock? lower bump travel, better tires, and more unsprung weight all need more spring. You might be bottoming out on your suspension which is really bad for traction.

To try and answer as many questions as I can...
Size of my tires is 225/40/18 but I have eibach sport line, with Michelin pilot super sports on 18x8.5 rims. I got my car aligned at a professional dealer but everything was not put on at the same time...I have rear lower control arms because when I put on the springs my car would not align properly without them so I had to get them. I am seeing her it looks like a strut bar/sway is not the answer. And it seems to be something else...I might take it to Toyota and get it aligned what specs should I get them to get it too?
Everything is new also. I have had the rims and tires for going on 3 months. The springs and stuff less then a month.
Below is a picture of my alignment specs Lord hoping it uploads.

The speed at which I'm taking corners depends...at about a 60 degree angle it starts skidding around 65 give or take

looks like it might be the rear toe

Yeah, the Sportlines don't give you enough bump travel. Sticky tires will increase roll and combined with not enough bump travel, you're finding the bottom of your suspension travel in hard turns. You could certainly use a little more camber front and rear, but the setup you have *should* favor understeer, if anything.

Also, where are you turning 60 degrees at 65MPH? That's a little brisk for the street.

EDIT: Not to say that I'm blaming the Sportlines for loss of grip, necessarily. Just pointing out a potential issue with the setup.

If anything, positive toe should make the rear end less likely to rotate.

I'm totally guessing. Even if that was gone, possibly I'm just thinking I drive a corvette but I was driving down the highway today at 108mph and I felt like my car was gonna start flipping because it was swaying so much, kind of like a roll and the under carriage felt like it was on water, or floating....lol best I can explain it

So I'm going to point out the elephant in the room. Can you drive? Everything you mentioned in the first post says you don't actually know how to use your brake pedal, steering wheel, and gas pedal properly. Suspension, tires, whatever; none of that matters if you are clueless behind the wheel.

Yes I know how to drive, whether my grammar and vocab relays that. My family and I have been racing/driving at VIR where I live for years, I've driven Porsche, GTR, Turbo-D Scion FR-S...etc. I don't believe my driving is the problem, as at the track it's hardly ever straight lots of twist and turns. And while driving these cars that would blow mine out of the water I have been fine, to say the least. No I can't go 150mph on the track, but I have nerve had anything like this pop up before.

Ok, just checking. I wasn't trying to be rude or offensive.

Didn't think you were! Just trying to clarify as I would like to get this issue fixed...seems like I might need coil-overs that would better suit my tire and rim setup. Or vice versa

OK then.

Looking st everything you've mentioned now, its going to have to be the springs and potentially blown shocks as well. You need to read up on what other people are using.

I'm pretty sure my shocks aren't blown...not sure what I described that would make you think that? Also, I have brand new springs?
