Hi I have a 1988 formula firebird with the ws6 suspension. I'm looking for possible upgrade options but I can't find much on the older ws6's I've wanted to drop a new k member under it, but all I can find are things for 4th gens. If anyone has any ideas the insight would be a huge help.

 

Before you upgrade anything make sure everything else is up to snuff. Things like bushings, ball joints, shocks etc. The first suspension mod should always be subframe connectors. A k member doesn't help the chassis in terms of handeling. Rather, its a cradle for the engine and aftermarket units are desireable due to their decrease in weight and increase in room around the lower part of the motor. Time to search a bit. There are 192837251 suspension manufacturers for these cars. I'd start poking around the forums and see what people are choosing.
