Body roll and tire spin

Body roll and tire spin
So I installed tein street basis coilovers on my car 3 months ago. Handled good and all. Moved to Dallas and recently noticed bad tire spin when doing u turns or higher speed right turns, tire starts to spin out and rear stats sliding outward. Do I need endlinks to tighten up the sway bar? I didn't notice this issue before I moved. I also drove to va from Louisiana and the back and trailered to Dallas. Maybe endlinks and a stinger sway bar? It seems the body roll in the rear is worse also, maybe contributing to the issue.

That might hold true, but the amount of force that is placed on an outer spring and damper is immense when making turns while a launch will have distributed forces between the rear suspension and the linkages that they all share.
I would start first by taking a glance at your shock bodies and making sure there are no leaks. Make sure the springs are seated properly and dont show excessive signs of wear or paint flaking (this may be a sign of binding).
Also, a simple test of just bouncing the rear end through the trunk floor can help produce noises that would otherwise go unnoticed while driving

Oh, re-reading again, and then googling, i thought it was just springs on OE shocks. I didn't realize they were coilovers.
Then yes, I'd say look for a swaybar related issue first. Alternatively, look for a possible diff problem. A diff that is locking too easily can produce that kind of behavior, as the wheels need to turn at different speeds in a turn in order to maintain traction. If they turn at the same speed, one of them will be sliding on the pavement.

Riwwp, I added the word coilovers to it to not get confused. Sorry about that. Could it be the roads? Didn't have this issue til moving here to Fort Worth, also the roads are very light so maybe the "sticky" is gone? Lol. I could understand the diff problem, not my strongest subject though, what would cause them to lock up too easy? I've been wanting a new one anyway but if I recall price is up in the $800's. Could someone enlighten me on the subject?

The factory diff shouldn't be causing this problem at all. If it is, I would think that it is a fluid problem (too old? Not the right fluid?) vs an actual failure. I would also expect, from what I know of diffs, that if you had an internal failure that it would fail 'open', not 'locked'. In this case you would get more inside rear wheel spin on tight hard power u-turns, but higher speed corners would likely not be able to put down enough torque to cause any sliding or spinning at all.

Regarding the roads... I highly doubt it. That would be a general loss of grip for all 4 wheels, not constantly the rear. UNLESS it's not the pavement at all, and actually it's your tires. For example 10 year old rear rubber but fresh new rubber. Even at the same tread depth, the rear tires would be much harder from age and thus have less natural grip. Or a tread depth difference in rain (but weather wasn't mentioned, so I doubt that either).
And that wouldn't explain any body roll (which a diff problem doesn't explain it either), if you are actually getting extra body roll in the rear. Body roll would actually be less if you had less tire grip.
All in all, I'd still point back to a sway bar problem first (front or rear), since that can affect both grip and body roll.

A guy I met yesterday with a mazspd 6 said it's common here for the roads to not be as sticky as other places. The front never lose traction due to not being under power. Like I described before it's only when full throttle is applied. I am unsure there is a lot of body roll, I'm thinking I'm imagining that.

A different rear sway bar and end links could tighten up the rear end make it even more loose. I know the my LSD is wore out and I am swapping in a helical style one from an FD
