One wheel? Could be positraction slipping too much. Need a diff expert to weigh in. I know my c3’s typically never did that. Car looks good, must feel great.
Edit:
Of course they are trying to sell a new rear end...
“ In addition to multiple gear ratios, Camaro owners also have a wide choice of differential options, depending on how they’ll be driving the car. “The factory clutch style limited slip differential does a marginal job of torque biasing in situations of unequal traction,” Capek explains.”

my warning radar goes up when a magazine article doesn't start with the whole truth.
here's the rest of what they didn't mention.... first, the SS rear is different from the 'regular' Camaro rear, second, the differential was developed from GM's experience with the GTO (Holden), and it is functionally the same as the G8 GT - granted it isn't the mack-daddy ZL1 (love their admission that the ZL1 could be better than theirs).
Most especially the limited slip. One huge problem with the C3 rear differential is the use of the drive shaft as its upper control arm. The clutches rely on spring pressure to put just enough friction on the side gears to make them limited slip... then the Corvette goes around a corner and the inner tire is dragging the clutches apart (those who don't believe cast iron flexes, it does).
The SS differential is functionally the same design, but since it's not trying to keep the tires upright on corners, it can do what it needs to do under all circumstance. That said, the plan always has been for a trutrac. I had one in my GTO, and it really was the only good thing about that car. The biggest hesitation continues to be whether or not the 3.27 gearing is correct for the motor. I like my 4 speed and I'm using brute power and a wide torque curve to mask that I'm "deficient" in the gear selection department... with that said, I need it to hustle off the line - and the cam I selected gives up some torque for hp.... and the other side of that is this transmission has the lower (numerically) first gear but there's even a deeper one that comes from similar vintage Camaros.
also, the tl;dr is I may need to put a friction modifier in... redline claims no, but it wouldn't be the first time that kind of advice wasn't exactly right.... also, I've found limited slips need a few miles on them to start working right - this rear hasn't been powered in at minimum 3 years and perhaps even much longer.... it came out of a 30k car, so it's possible that it could have been sitting since 2012.... we'll see, but the biggest questions - vibration and burnout have been answered.... now to figure out what the starter's problem is....
