Default Replace my pro-kit with........?

I have an iron block, and it sags in the front with the LS1 eibach pro kit, even with the hose mod in the rear.

My first thought was to just use the LT1 equivalent in the front and keep the rear springs, but the rear springs are way too soft. even with adjustable shocks, i have to keep 5-10psi in my air bags to keep from hitting axle to body under normal driving conditions.

What complete set should i get to replace it?

1. The car will be road-race or autocross oriented.
2. No drag racing.
3. I don't mind a relatively rough ride, as long as it doesn't dive or give much.
4. Can't afford coil-overs.

Not to be harsh on you, but you want to road race/autox with an iron block and stalled auto? Thats going to be a bit of a handful.
That being said with your more unique situation you may want to try different springs rates from ground control to see what suits your needs best.
If you want a "starting point" Id suggest the koni/strano setup as it has multiple national SCCA wins to back up that it actually works.

It might not always have the automatic, depending if i do more road racing vs autoX. For the time being, I'm just paving the way.

I'll have to agree that the weight on the nose could present a problem, but you can work with it - just have to keep it on your mind.

If your budget doesn't allow for a new setup and you want to raise the nose a little, why not try our shock spacers? This will bring the front of the car up approximately 1/2-inch. They're cheap, and we sell them to a lot of people looking to correct similar issues with Eibach springs.

i'd like to just replace the whole set of eibachs with BMR's or stranos, but i have a limited amount of cheese i can allocate to this project without the wife punching me in the throat.

so i may try out the strut spacers with the pro kit and see if that makes enough of a difference. if i keep the same springs and correct the sagging issue, i may be able to afford a complete set of koni's to replace the AGX set i have now.
