which set of lowering springs?
alright im having a hard time figuring out what springs i want. i know i want at least a 1.75 drop front and rear but would prefer 2 inch or more. i know everyone recommends eibach but their sportline springs are 1 inch front and rear and they pro kit is 1.6 front and 1.3 rear. i want it to be lower than that.
canuck motorsports= 1.6 drop front and rear and about $175
intrax= 2" front and rear and a little over $200
eibach sportline=1.6" front 1.3" rear and about $250
eibach prokit= 1" front and rear and about $250
sprint= 1.75" front and rear and about $215
dropzone= 1.75 front and rear and less than $150
zenn= 1.7" front and rear and less than $150
anyone have any expierence with any of these? let me know if i left any out thats all i could find but im sure there is more. idealy i would like to stay under $200 and get as close to a 2" drop as possible and having a firm comforatable ride. let me know your suggestions.

Don't buy Zenn lowering springs. The rear springs are too soft and made my car sit too low in the rear. I had to put my stock rear springs back on. Front looks great, but the rear springs dropped it down about 3". Wish I had bought the dropzones.

I've tried both Eibachs, I personally prefer the Pro-Kit even though its the mild drop between the two kits. I didnt like the SportLines because IMO the rates are a little too soft for the ride height and the rake is too extreme. But again, thats just my personal opinion.
I think you should ask yourself what the application will be. Along with the ride height you should also be looking into spring rate. You wanna make sure the ride isn't gonna be too harsh or too soft (per your personal preferance), and it has to be a good match for the shocks/struts (or vice versa). Some springs are linear meaning a static rate, some are progressive meaning a range of rates. So if you have a preferance there then be sure to consider that.

well i want it to be a firm ride but i really would like about a 2" drop. im really doing it more for looks than performance but since im buying them id like to get a little of both. i have V6 springs i cut to lower my car and it looks great but is too low and a pretty rough ride. does anyone know the stock ride height for an 88 iroc? that would help tremendously. that way i can measure to see about how low it will be with each type of spring.

I have read more bad things about intrax than good things. If you indeed want a 2" drop with a quality spring than I would look harder at the sportlines.

If you want to slam the car I say go with weight jacks and custom length/rate springs like I did. This way you can get the spring rates you want and the ride height is adjustable. If you aren't down to spend that much, you can still go the custom spring route. 2" is pretty low for a street car.

Ground-Control makes the weight jack system.
Personaly, I would get the G-C front setup, but get the all-star rear perches, then you can use a standard 5" spring in the rear, instead of the pig-tail spring. Their rear mount seems a little more strudy then the G-C one.
Try calling Strano parts (www.stranoparts.com), Sam Jr. will get you hooked up with the right setup, if you are wanting to go with weight jacks.

If memory serves me right it is about 450 for the weight jack set up. I have the ground control versions. If you want to slam it get 8" springs. I will be going to 9.5" springs to get my car up a bit. I got mine from Strano's and I buy many parts from there.

yes i have read a little bit about the weight jacks setup and it would be ideal for me but i cant afford that right now.
SnkSknrZ28 that iroc looks sweet. i am a little worried about the ride i dont want it to be too rough b/c thats part of the reason i am getting new springs the springs on there now that i cut are pretty rough.
does anyone have any pics of the sportline kit? i wouldnt mind getting those i mean 1.6" is fine for me but i dont want the car to have a rake i want it to be the same front and back.

Also, has anyone heard of the tenzo lowering springs? They are pretty cheap on ebay (like $120 shipped) but I can't find any info about the spring rates or anything... I'll probably stay away from them and go with eibach since I am more confident in their quality. So then I'm stuck deciding between sportlines and pro-kit.

2 things to keep in mind considering that 3rd gens don't have much suspension travel to begin with, lowering a 3rd gen 2" will greatly reduce your available suspension travel. So you either get nice soft springs and slam into the bumpstops as you cruise around or you get really firm springs and get bounced around by the rate. Unless you live in glassy smooth road land a lowered 3rd gen will have a rough ride. Either way you must have premium struts, because your going to need some serious compression damping to stop the sloppy soft (in my experience eibach pro-kit) springs from hitting the stops or some serious rebound to damp the really stiff springs. The best setup i've experienced is the guldstrand kit. i have a good deal of experience with the slalom coils, the rears might need a slight trim.

If you have stock struts/shocks think about getting new ones soon. Lowering your car on factory shocks/struts will kill them fast. I run big tires on the back and the thing scrapes alot over 40mph on any big bump in the road.
I like the pro-kit more then i dislike it though. If big dips/steep driveways and/or getting a jack under your car is not a concern or a problem then get the sportlines. Its just a pain when you jack your car up frequently like myself. Plus it gets stuck on the drive on wheel alignment racks, and i can only fit 3 arms of a lift under the car.
