Y87 Package

This along with T-Tops is the only thing my car lacks option wise..what was included in the Y87 package?

The Y87 3800 V6 Performance Package upgraded the vehicle with Zexel-Torsen posi-traction differential (same differential used on V8 models), a dual outlet muffler, a quicker 14.4:1steering ratio (same ratio as V8 models), 235/55-16 tires. The Y87 package also gave automatic cars 3.42 rear gears, whereas the manual cars but kept the 3.23 rear gears.

My car has 3.42 RWD gears though..

So.. is that not what it says lol?

Lol...did u read my post? I said i do not have Y87..So why do i have 3.42?

Ohh, gotcha. I thought you were originally asking about the Y87 because your car came with that package. I assumed yours was since it has the ground affects kit and dual exhaust already.

So why do i have 3.42 and dual exhaust but no Y87 rpo code? Does that switch in the car for LSD come with y87?

Ah, you must have the W68 performace package. It's a step below the Y87, comes with just the ground effects and dual exhaust.

The w68 wasnt a performance package. Its just the appearance package which is JUST the little "body kit" on the sides, front and rear

Ok, well same thing... you know what I meant! :slap:

But it is semi-performance.. because the W68's do come with the dual exhaust setup that you've got. At least every W68 I've seen at least.

dont all firebirds have dual exhaust??? Still doenst explain the 3.42's..

Nah, the base model Firebirds only came with one side outlet exhaust. Not too sure about the gears.. Possibly special ordered? Or shoot, maybe the factory had a mixup or something. That ones over my head.

Wow i didnt know that..Also it does say GU6 on my door so i definetly have 3.42's right? Its not like they could accidently put GU6 when i dont have it correct?

Not really sure, that's just weird. Only thing I can think of is it was specially ordered with the 3.42's.. But if you absolutely want to be sure that it does have those gears you gotta open her up and see.
