Rear end sliding out.... I have Koni 4/4's and Sam's springs with isolators. All poly/poly suspension BMR lca, BMR relo brackets, BMR phb, and 315 Nitto 555r's. I have the front shocks set to 3 from firm and the rear full soft. At low speeds, whenever I turn corners or slight curves, the rear end slides out from under the car under low to moderate throttle. There is no wheel hop with it or bounciness. Straight line traction and high speed handling is fine it's just the low speed stuff. I literally can't give it that much gas when I switch lanes fast because the back end slides. I have drag radials so I don't know what's up. No strange noises. Should I turn the firmness of the rear shocks up?

It's been cold, right? I'll be money this started when it got cold.... Summer and/or a competition compounded tire really don't work below the mid 50's well at all, and the car makes more power when it's cold too.
You are simply spinning the tires, which aren't sticky because it's been not super warm lately (even in TX). And don't forget that soft compound tires also heat cycle out, as in the rubber gets hard like an old pencil eraser with miles. So that could be happening as well, or on top of the temperature having been cold at times.

No, they cause roll oversteer, he seems to clearly have power on oversteer from wheelspin.

You always have better straight line traction because the power is applied equally to both tires and without lateral load involved. The other issue could be you're just overwhelming your stock limited slip. Very common, and the first sign other than inside rear wheel spin is increased, and snappy power on oversteer.

The limited slip is not the same as putting in new bearings, gears, etc. If they put your stock LSD back in (and I'm sure they did unless you fragged the axle), nothing will have changed there.

The Torsen, being a torque-biasing piece, will
send torque unequally to spinning tires. Spinning
tires don't hold lateral position, unequal wheel
back-torque (as will be had from axle roll torque
reaction) makes an unequal torque split and an
off-axis wheel thrust vector sum and the car will
try to rotate (yaw) as a result.
My GS-D3s used to have no traction at all when
the air got down in the 40s.
