Well, I just pulled into my driveway - and kinda floored it, b/c i have no power, but its fun to spin wheels in rain
Anyways - I got some really nice spin... And I have always assumed i have a open rear, since as far as I know, its stock (i know its 2.77 or 2.73 I forget which), and I have not the RPO code fer limited slip. But it left 2 tire marks. How?

 

Under equal load both tires will drive it's just that when push comes to shove the one with the least traction will take over. Now if you are not sure what you have just jack up the back end and with the car in Park try to turn one of the tires. If it won't you have Posi. If it will then it was just a fluke.

 

Ah, i see. I waas under the impression that only one wheel gets power. But it is only sorta like that. Thanks!
