Whats the difference in a ws6 car (suspension wise) and a non-ws6? Springs, anti-sway bars, anything else? what about the torque arm, is it specific to ws6 only?

Looking for a car for an engine swap and wondering what is involved in bringing a base firebird's suspension up to snuff with the ws6. Thanks!

 

I think you have most of it named
I think the LCAs have a harder bushing in them .. all the per package cars and 1LEs had them including Pace cars

 

Different springs, sway bars and wheels of course. The WS6 springs werent as stiff as the Iroc springs. The WS6 sway bars and the Iroc bars are the same size. The Irocs have wonder bar and the WS6 car do not also. I have never heard anything about the bushings but it could be possible......

 

Even if it did have different bushings, it wouldn't be worth the hassle of changing them.

 

Your right!!! I put in poly and boxed my stock arms for a wopping 50$

that was back in 91
