I'm in the market for aftermarket springs, and I hear from alot of people that KYB shocks/struts and the pro kit are great for the street. The only problem I have is that I don't want my car any lower than it is now, someplaces I have problems scraping in driveways. Can anyone with the prokit measure the distance from the ground to center of the front bumper?

 

About an inch. It porbably wont lower it much at all. Most of the cars have the original springs in them, they are sagged and worn out.

 

exactly! thats what i here also..

 

about an inch? is that the drop or the measurement he was asking for? Cause if thats the measurement, MAN ! thats low...

 

I just installed a set of Eibach pro kit springs on a customers 88 IROC, it sets about an inch lower than it did with the stock springs.... Not too low, but it is noticeable.

 

i didnt notice any drop after installing my ProKit and new (thicker) GM spring isolators (replaced 145K mile springs), but i am still happy with the ride and handling quality, and i didnt really want my car lowered anyways.

 

How do the companies measure their "Drop", anyway? Comparing their springs against new stock springs that haven't settled yet? They -should- compare them against 100,000 mile springs.

 

TomP, thats why I wanted to ask someone to actually measure the distance from the ground to the front bumper, I'm not sure if the drop is in relation to new springs, or the old sagged ones. If the prokit leaves my car at about the same height, then I'll get it. If it lowers it, then I need to get moog springs or something like that. Some people with a late 80s car say they dropped an inch almost, and some with a 91 or 92 say it didn't do anything when they replaced their old springs.

 

if your worried about your car dropping then just get a new set of stock springs. I have a stock set out of a 91z28 that have 30K miles on them. There yours for $60

 

Apperantley not what he was looking for. One inch is not that bad, it is a noticable difference. Like I was saying though most of the springs are worn out. They are already 1/4 - 1/2 lower than the day it left the factory. The sportlines are something like 1.6" front and 1.5 in the rear. I think, they might be a single measurment drop, basiclly 1.5". That is a little to low for me. There is also the drop spindles, if you can find them, that have a drop for 2" in the front, and the cut the rear springs to be even.

Here is a shot of two inches:

anyone have pics of cars with the Eibach pro kit?

 

here is my Eibach Pro Kit and new GM (thicker) isolators

 

That looks like it's around stock ride height - maybe even higher. It sure sits higher than my 83TA with 100K on the springs.

Do you know the distance from the fender lip to the ground - I think stock is about 27 inches.

I'm installing a ProKIt and this new GM isolator business is worrying me.

 

for stock hieght, before I changed my springs to DropZone they were at almost 28" rears..and my car didnt sag a bit. heres a picture before i changed them.

 

Here are pictures of the 88 IROC that I just installed the Pro- Kit springs on....

I did not take a tape measure with me when I went over to take these pictures... Sorry. The car is far from being too low, and it rides / handles very well.

 

RU -QUIK

Do know the tyre size he's got there.

Edit - so i can figuer out the wheel size - looks like it's less than a 26 inch wheel.

Thanx.

 

This low:

 

Those tires are 245/50/16 BFg's .... The rubber spring isolators were not replaced, so they are a little flatter than new ones would be.

 

25.6 inch wheel then - same height as my 275/40/17s

I hope my old isolators aren't trashed because they're going back in.

 

I have an 88 w/the same springs. I have 245-50-16's on there now and the car sits pretty close to the tire. Don't get me wrong,the car handles like its on rails and looks MEAN but the ride quality sux. If you don't mind shakin a few fillings loose get them.

 

Thanks for all the replies. I'm definitely getting the pro kit. My car has stock springs and is as low as those pics are. They are definitely sagging.

 

Before

FR: 26.5 FL: 26.5
RR: 27.75 RL: 27.75


AFTER

FR: 26.5 FL: 26.5
RR: 27.25 RL: 27.25

 

1" drop front
1/2" drop rear

= happy, cept i now have a noticeable rake with my 17s...

 

91 Formula 350.

Front 1 inch

Rear 3/4 inch.

Looks great.

Side note, if u can afford it get better shocks/struts, worth every penny once u experince it :-) Never thought jumping to Bilsteins would make my day but I will never go back.

While doing the suspension stuff check out the strut bearing and replace them, they always get overlooked on our cars

later

im trying not to spend money right now, id appreciate it if you reframe from telling me anymore how nice bilsteins are....i will never have a bank account if i stay on TGO...LOL

 

on my old ride the height of the car
left front: 26.5
right front:26.5
left rear: 27
right rear:27.25

 

While i never had anything other than Bilsteins with my Eibach's I LOVE THE SETUP! I couldn't imagine going with anything different, they were worth every penny i spent on them! GET THEM, YOU WON'T REGRET IT!!!!!
