is rpo code g80 ---limites slip diferential, posi-traction a standard option on camaros. acording to a sight i checked it said it was a 100 dollar option. anyway im just curious.

 

g80 is.... limited slip posi

 

right but is it a standard option is really what im interested in. because according to my rpo's i have a posi 2.73 rear end.

 

they probably are but mine came with 3.42 non posi... so i guess it all depends on what engine it came with... not to sure tho

 

What do you mean by "standard option"?

 

standard option is something that is automaticly put on a car or at least thats my understanding.

 

im thinkin that it was probably an option at the dealer and if the orginal buyer wanted it then he would request it but like i said it might be based on the engine size.... more power=better rear-end to handle the power

 

true. its the 305 tpi motor not an incredibly powerfull motor with 2.73 rear gear.

 

i don't know man...some v-8s are posi some aren't i guess....it could be possible that your rear was swapped in by a previous owner but i don't know how likely that would be but hey anythings possible

 

so true, so true.

 

It was not standard on all Camaro's, but was a required option with other option codes. And since it's listed as a $100 option, it would be an addition to a standard optioned car. A standard option would have no additional cost.

 

As 1991L98 states RPO G80 was an extra cost option,in this case $100.It was an upgrade from the standard open rear end differential on all F-Bodies.It was required when you ordered RPO J65(4 wheel disc brakes and this also required ordering a V8 engine if it wasn't standard in the model being ordered).
