Default TT-02 Spins to CCW, pushes CW

Hey guys this one has me stumped. This car will spin when pushed hard on left hand turns or with abrupt throttle during a corner, but to the right it will never spin no matter how hard I mash the throttle. On a hard turn in with no throttle it will start to slide turning left, but it will never do it to the right. I've put it on my arrowmax setup station and the numbers are all good. I have the Tamia CVA super mini shocks. The car goes straight under throttle and off throttle. The turning radius is exactly the same, I physically match the diameter of the circles on flat concrete. There's no excessive play. The lateral balance is pretty close, not enough to cause this kind of nonsense. All four hubs are mounted properly, none of them are upside down. I have a spool on the front and very light grease in the rear. Heavy grease in the rear didn't make a difference. I know the wiring is ugly, I just converted it from a shorty with the ESC on the battery side and I'm not going to dial it in until it handles. This is on contact 32s and yokomo 28a's. There is no servo binding at the endpoint, I make sure to back it off to zero buzz before I do the physical circles to even the steering completely. I just printed some -2° knuckles and it did not change the handling. I've used the setup station before and after these knuckles and they are perfect at -1 camber and 2° toe in per side. I was hopeful that a lot of rear toe and would help but no. I'm running a savox 1258 and It centers great . The shocks are all the same length. I have it set up with a reasonable for this chassis ride height and it has about a third of the travel in droop. Basically when I lift the car the springs have just a little free play. This setup works reasonably well on any other touring car I've used for a base setup. Interestingly I have a Euro Truck that does the same, but I purchased it used and the guy who had it was a cheater and it has weights that I took off and the rear chassis has part of it glued together so I can't disassemble it and check it out. On that vehicle I assumed it was just something the guy had done. Now I have the same problem with this car. I've built of cars, I have x-ray t4, TC3, tc4, x-ray F1, cero V2 and sport. I've probably built another 50 cars over the years for off-road. I'm ready to throw this thing at a wall. I even went so far as to add extra preload to only the front right shock and it's still did it. I've swapped the shocks around. Ugggh. I hate this car!!!
