I've used the search and read quite a bit about the differences in the types of setups. For sure I want to go with a FBSS setup w/ electric valves and definately with shocks and swaybars. End result I want to be able to really drive this car. I don't need to be able to hop or anything I just really want a good ride and stance. I know I may get the bug and want to go further but for now that's it.

I still have a few questions. What's the recommendation for front and rear bags with regard to the rated capacities. I have a 91 wagon and don't know whether I should go with the 2500 or 2600lb bags in the front or rear. What's the drawbacks, is it travel?

Is 3/8" line and valves sufficent or is 1/2" recommended? I've also heard about a mixture of both.

Also if I'm not notching the rear do I have to extend the rear control arms? I have an nice set of GW LCA on there I want to keep them.

As with most, budget is a concern. Is there any places out there that currently offer a good deal on the bulk of the "kit" (for lack of a better term)

I've seen this sites in previous posts
also http://www.bagsandbrackets.com

Any advice is definately appreciated. Also a brands of components to try to stay away from?

Bag size:
The "2500 lb" bags will be what you use up front. In the rear either size should fit.

Line size:
For what you want, the 3/8 is more than sufficient. 1/4" would even work fine. 1/2" line is for if you want to go crazy, and isn't really all that great for "real world" use.

Control arms:
The GW ones you have now will work fine, although if you have a 93+ Sedan the goofy uncentered wheel problem will become more pronounced as the car gets lower. The extended arms become a requirement with large diameter wheels or large notching.

My recommendation for a retailer/kit supplier is, and likely always will be, Air Ride Technologies. Their products - especially the valves - are top notch and their customer service has never done me wrong. In fact, they've gone above and beyond what I expected or even required. The only downside is they are expensive. Then again, cheap parts are cheap parts, and quality isn't cheap.

yup front i would go wit hthe 2600 bag. Or slamspecialties 7" bag. With the 2500 you will need more pressure to lift the car and it might ride stiff. IN the back you can use a 7" bag.

3/8" line and valves would be just fine. Parker valves or SMC's are good valves.

Ok.. another thing is I need to rebuild my front suspension... Is Moog rubber bushings the way to go or energy suspension? Not sure if the flex is good or not since you'll be going up and down.

Any other places to look to start piecing parts together?
