Hotchkis springs vs. Eibach ?
Has any one used either? I kee reading that the Eibach prokit is too soft but have not heard any one use the Hotckis springs.
Any info would be appreciated!

Never had experience with the Hotchkis;I've always went with the Eibach springs. I have the Sportlines and have liked them very much. I haven't actually tested on a skidpad for g's,but around a specific curve on a course I gained almost 15 mph after installing just the springs,and 25 total with the springs and bigger sway bars. Hard braking is better because of the extra force on the front tires. But as far as the differences between the two companies,I can't offer any opinions.I can just tell you that I have been happy with the Eibachs.Here is a picture of my car with the Eibachs installed.Not a good pic,just the only one I could find at the moment.

I have the Eibach Prokit springs on my 86 IROC and definately
noticed an improvement in handling after putting them on.
They do ride quite a bit harder than the stock springs, but the
lowering isn't substantial. I haven't ridden in a thirdgen with the
Sportlines, but I can say that the prokit definately does not ride soft.
Also, my IROC has 245/45/16 Bridgestone RE730's on it so
this may add to the hard ride.
I also gained about 15mph around turns from stock springs.
Overall, I think that the increased handling would be
justification for buying the eibachs.
By the way RSSpeed, you're car is looking sweet,
I hope to do that with mine in the future.

I have the Hotchkis on my Z.I felt the Eibach lowered the car too much and the Hotchkis was just right at 1",with great handling and ride.

The Eibach Sportlines are higher rate (stiffer) than stock springs but do not have as high a rate as the Eibach Prokit springs.
The Sportlines drop around 1 5/8" - 1 3/4" in front and around 1 1/3" - 1 1/2" in rear for a little bit of a raked look.
The Prokit drops around 1" front and back.
The Sportlines are primarily to get a "slammed look".
The Prokit springs are primarily for improved handling.
The Hotchkis springs are very comparable to the Prokit springs.
