Is the 4T65 posi?

For the first time since I got my GTP last summer I decided to drop the hammer in a parking lot. It did a nice burnout but still accelerated pretty well even with the TCS off. When I came back to see my marks there were two big black ones where my tires used to be. I figured since I was accelerating that it allowed both tires to spin. Then I really decide to get after it. I set the emergency brake and hit it. Wow!! It pulled the damn back tires. It still moved ahead but this time a whole bunch of smoke flew everywhere. It was awesome. Still there were two individual black lines. So is the 4T65 posi? I know they don't come with limited slips. Shouldn't one tire just spin if there isn't much traction. Just wondering.

Thanks

Nope, the 4T65-E is not posi/limited slip.
You'll lay two lines of tread if traction is equal for both tires.
Only when one tire has more traction than another will you only lay one line.
