2 different types of Eibach springs?

There are two types of Eibach springs, which one is better? A lot of people are saying that spindles are th eway to go. But they don't give you handling, do they? I want the lowered look, but handle like a Vette. I don't want to low, just enough to look good. What do you guys mean when you say springs mess with the geomotry? It'd not going bounce down the road like a honda is it? I want it really stiff but i don't want to bounce like those stubid honda's. What do you guys think?

im on the same boat you are.. check out my thread.. https://www.thirdgen.org/techbb2/sho...threadid=89513
I think im going to go with the sportlines.. They are lower, i heard that the Pro-kit is mainly for people who want a stiffer rid\handling but no realy any lower.. And with spindles, i haven't seen a drop any smaller then 2.5". im looking for about a 1.5" drop. so springs would be the best option.. Plus as long as they dont give any more then -1* of camber, we would be pretty well off.. Any more then that then we should get the alignment kit.

The Eibach Sportlines (the lower ones anyway) are easily had because the are distributed everywhere under the sprinds sold by Edelbrock. These are the sweet deal going!

if you want a ruff ride an a 2" or lower from "stock" stance then go with sportlines.

if you want a 1.5" drop and excellent ride an handling go with pro-kit.

remember, your stock springs are old and sagging from years of abuse, so when you put "drop" or "sport" springs, they won't necessarily drop the car alot. the stock height of 3rdgens is rather high.

2" or lower an you run into definate camber problems as well as drivetrain power transfer problems; you'll also need an adjustable pan hard rod.

sportlines are stiffer than pro-kit by far, but in no way meant for auto-cross...pro-kit is what you want if your going for autocross, look to your shocks an struts to adjust firmness in the proper area.

the pro-kit out handles the sportlines in everyway, but they don't lower as much as most like.

gmhightech performance did a story on a blue 91 z28 that had the pro-kit, they modified the springs by cutting 1/2 of the top coil off the front springs; this gave the car it's desired lower look without sacrificing the driveability......so they said.

i put the pro-kit on mine an loved them, but they weren't low enough so i followed the article an couldn't be happier; the ride didn't change one bit, but the stance did; i had to have the front re-aligned and put an adjustable panhard rod to compensate for the lowered look........but, it was worth it.

from a true "stock" height, my car now sits roughly 2 1/4 in the front and 1 3/4 in the rear....perfect for me.......the fact i have ground effects i can't go any lower; if i hold my hand flat and turn it on it's edge it just fits under the side of the car.

as you can see with the above pic i can barely put my thumb in between the tire and the fender unlike the old springs where i could fit my whole hand....

here's a profile view for my last pic to give you an idea of the stance; sorry i don't have any true side pics to show the difference.
