I saw a Trans Am? today that included the following RPO codes on the driver's door:

WS6
WS9

I have read that a WS9 code is for a formula and that a TA has a WS4 code?

Can someone help me out?

 

A search for WS9 and Trans Am would show a lot of threads on the subject.

The short answer is that all Trans Ams start as Formulas as a base, then get the Trans Am conversion from there. IIRC, Y82 is the T/A code. WS6 is just a suspension package that is available on the Formula as well.

Any bets this reaches over a page of the same kinds of responses?




Edit - I guessed on the search parameters, but it was a good one. Searching for exactly that found this - https://ls1tech.com/forums/showthrea...t=WS9+Trans+Am as the first result.

 

all TA's get the Ws9 code

Yep, same here. I have the both codes too.

 

WS6 code is for the upgraded suspension, lower air box, ram air hood, 17x9 rims with WS6 center caps

 

Thanks for the posts.

 

iirc you cannot get a ws6 formula

 

you can, but only certain years. im sure ACW will see this and give us about 5-10 links with info

 

Yes you can. They never built very many of them.

 

Who, me?

Formulas were available with the WS6 Ram Air option from 1996-2000.

1996 - 524 coupes
1997 - 473 coupes, 41 convertibles
1998 - 221 coupes, 2 convertibles
1999 - 175 coupes
2000 - 232 or 233 coupes
