of the 2 years i've had the 7 i've never done a true burn out.. so the the other day it was beutiful out. the road was the perfect temperature so coming out of a left hand turn the road was dead.. so i stopped revved it up and popped the clutch.. awesome spin and too my suprise in my rear view mirror TWO long black streaks of tire... does this mean i have lsd? i had no idea its a 1990 GX..

 

no it means you launched in a straight line...

edit: but I wouldn't put anything past anybody - check for a tag on your diff.........or try the burnout again but with one wheel in the gravel and one on the pavement.......

 

so they have posi track? i'm confused isnt lsd when the other tire compensates for the other tire slipping? or do both turn at all times...

 

No mazda has a Positrac. Positrac or Posi Traction rear ends are GM's name for a limited slip differential. Calling a Limited Slip Differential (LSD) as posi trac is like calling all refrigerators Kenmores.

There are several type of Limited Slip Differentials. Some transfer the power to the wheel with the most traction, some lock the rear so both wheels must turn at the same rate, some slip one wheelm, while providing power to another.

And almost all FCs can do a two wheel rear burn out, regardless of if there is a LSD or not. Worn struts or suspension, crappy tires, and many other things can make it easy to break both wheels loose. By no means breaking both wheels loose should be considered any sort of a test of wether the vehicle has a limited slip differential.

And next time put a real title on the thread... instead of something lame like "question" you should have created the thread with a title that actually reflects what you are asking.
