Hello
I have an 89 trans am... I would like to know if there are obvious signs of having the performance suspension... My car says it on the lower dash panel but, it might be there for looks... Please help if you can
thanks

 

check the rpo codes, probably in the console glovebox if you still have the sticker. the ws6 code should be there if you've got it. while you're at it, you can decode the rest of them here

 

Check the RPO code for WS6.

 

ok Now I dont have the rpo codes anywhere in the car

 

It is to late to worry about it now, you should checked before you bought the car. Someone could tell you the sway bars sizes and etc.. Then it means getting under the car and checking if it still has the old parts. Not worth the effort in my opinion.

 

I am rebuilding the car no matter what but, would like to know for my own info

 

Look on the inside of the rear wheel well compartment lid, that is where mine were on the '91 Formula. One of my Firebirds had them on the inside of the center console glove box. If not, then get the complete documents on your specific from PHS (Pontiac Historical Services) - well worth it!

In third gen Firebirds the WS6 package was real mechanical parts, better ratio steering box, specific wheels/tires, springs and roll bars. All obtainable searching this website if you need specifics. There's a member with an excellent Formula website, all Formulas got the WS6 package. Happy hunting!!

 

thanks will do!

 

Measure the front sway bar. WS-6 should be 36 mm
