i was doing some reading on here and came across the g80 build code. I am currently in the process of buying a 2002 ws6, and before reading this i thought all automatic ws6 trans ams came with a 3.23 limited slip rear end. am i wrong? i have not taken the time to look at the build codes yet as the car is not in my driveway yet. just a little clarification please..

thanks in advance,
Bruce

if i'm not mistakin the g80 is the code for limited slip.........for gears look for codes like gu6,gt4,gu5........gu5 should be 3.23

G80 is the code for 'posi'.
Codes for rear axle ratio are GU2-2.73 and GU5-3.23.
Don't know if it applies also to WS6 TAs',but Z28s' required purchasing the performance axle package to get the 3.23s'.

I have also seen z's with 3.42 factory ordered gears. Friend of mine has one, bought it new. Yes g80 is gm locker code.

Z28 w/3.42s'(GU6) is 6 speed.
Z28 w/2.73s' or 3.23s' is A4 automatic

so are all ws6's "posi-trac" or was it an upgrade? my buddy has a 01 z28. right now physically out weighs me by about 40lbs. and i am trying to get every edge i can on him. so i am wondering/hoping the ws6 comes with some better factory options....

Hi,
ws6 325hp/350tq same engine in wu-8 -ss camaro.
A-4 maybe a tick slower than m-6......reaction time and driver are important...
13.2 to 13.8 @ 100-105..........JIM

Greetings once again, :
i would jack up the rear end. Mark the tire and drive shaft. Spin the tire one (1) revolution and count turns of drive shaft 3.42= almost 3 1/2 turns and just a little over three turns for 3,23. Good luck and let us know the verdict. This could be a new one if true factory option odered rpo.
Have a great day. Jim

Im pretty sure all ls1 engine cars do but not the v6's.
