Oh, I've def broken all 4 tires loose on a sweeping left. That was with JB4 map 1 and 245 square re01r's. The torque on this car is just absurd.
Absolutely, the idea system would be a new "standalone". That would take some serious backing/coin to devise. Right now, that may not be feasible, but in the future, I think it will be. Alpina rewrote the x-drive for the B7x and there are rumors that the new m3/5 might be available with AWD. Also, check the link I posted a few hours ago. That essentially hijacks the stability control systems and lets you tune how much slip angle you want at each axle before safety systems cut in. Potentially that, plus a rear LSD may work...
Great looking Shiba, by the way. I had one growing up!
