Upgrading suspension on '89 Park Avenue... Opinions?

I know it's not a Beretta, but this is the best site for good accurate information, so I'm asking here.

The car is a factory FE1 car with air suspension. The air shocks travel rate is 15" - 21", but if I was to switch to the non air suspension rear struts, the travel is 13" - 21". I'm not sure what would be better performance wise, as I plan to upgrade from constant rate to variable rate rear springs regardless with FE3 front struts and springs, along with all FE3 sway bars.

Would rear air struts be softer? Or would I be better off with rear air struts due to less travel rate? Opinions?

Depends on what kind of ride you want. I love those old H bodies, that air ride is about as cushy as you could get. Otherwise with a variable spring it'll be still soft just not as even as the air ride will be.

I want a firm ride, but I don't want it to ride like a brick... Makes it a tough decision!

I would go with the air ride. More suspension travel to me indicates more room for bounce. You don't want bounce.

As far as the springs, variable = progressive. Eibachs are progressive. Nuff said.

That was sort of what I was leaning towards as well, and the same reasoning. Looks like my game plan is set!

Decision has been made, I'll be using Monro quick struts up front with air struts in the back. Variable rate rear springs as well!
