What suspension for GS or LS

I am looking to get a Lexus GS (all) or LS (89-97).  But i don't want to jump into a car and wish i would have done my research.  So my question is; what seems to be the most popluar suspension set up for each of these cars.  I know its pretty much air bags or coilovers.  But it would be helpful to get a list of suspension companies you'll are using. thanks for any and all help.

Search.

i have done plenty of research and searched this forum up and down.  I was just asking what the majority of people are running.

The big two coilover companies for VIPStyle cars: Tein, JIC
The big two airbag companies: AirRunner, UniversalAir

don't forget easy street air.

I had a chance to see poyet's GS ( luxuryJcars.com ) with easystreet air and it was great. total control.

thanks alot guys that narrows down my searching alot
