Actually, I always leave a nice 2 line patch. I've done very short burnouts even on new sticky tires. I guess the GS's open diff does a decently good job of throwing power to both wheels. Only thing I find difficult with the open diff is to hold a drift or go sideways. The LSD diff makes it MUUUUCHH easier

I know what you mean by open diffs leaving a 1 wheel peel. I see it all the time in my friends Camaros and Mustangs. I guess the rear diff in those cars aren't as well engineered lol.

 

That's because their not a Toyota!

 

I also seen a 400 with a tc spin both wheels on open diff.
One thing I found weird was if you try spining the wheels with the traction on, the left wheel get the power. When you turn it off, then the right wheel get the power
LSD makes a big diffrence in cornering as well. You loose some body roll, you can also corner hard and exit hard without the car feeling some what unstable, liike on open diff.

 

All very good points guys...thanks for adding!
