Spring help

I have recently purchased a 95 T/A that has been lowered with Eibach pro springs, has Bilstien shocks. I am looking to change these springs as they are too low and ever time I hit a bump they bottom out on the drivers side. I autocross this so this needs to be fixed. Any ideas what kind of springs would be good.

Re: Spring help

Eibach drop the car only about an inch. I run my car in ESP and it's dropped more than an inch and I'm fine. I think something else my be the culprit here. Are the front shocks still dampening properly?

Re: Spring help

They seem to be working fine, I really dont know how to tell if a shock is bad other than fluid leaking. If I knew how to post a picture on thisforum I would put a pic of car up so all could see , it is pretty damn low.
I have already installed LG Motorsports LCA's and a BMR double adjustable panhard rod, it has LG world challenge wheels 17x10 and BFG GForce rubber. but nothing seems to keep the tires from scrubbing the wheel wells when hitting bumps or dips.

Re: Spring help

When you hit a bump or dip, does the car oscillate more than once? Kinda like the way jello oscillates when you hit it. If you are mathematically inclined, think of the dampening harmonic function.

Also. Do your wheels shake cornering? I suck at diagnosing problem, usually I'll ask someone to ridealong to find out what's wrong. But there are alot of ppl with your setup and they don't seem to have the scraping problems you describe.

Re: Spring help

I have not noticed any problems when cornering.
If it is a ripple or dip in the road sometimes it will scrape a couple of times, what it is is the outside edge of the tires are scraping on the inside of the fender wells.

Re: Spring help

Has anything else been done to the car? Are the swaybars still stock? Rims/tires? You shouldn't rub unless something else has been done (larger or offset rims/tires), or your struts are set too soft for the springs.

I have a set of Eiback Pros on my SHO. With Blizzacks, I rub over large highway dips in the road (car actually gets light on one in particular) but with the set of G-Force KDW it doesn't. It's the height of the tire that makes the difference for me. My Koni settings didn't make any difference.

I am running stock size/offset rims on both sets of tires.
I just stiffened the rear swaybar up by using a much better design of stock dimension end-link, and the car handles flatter. I'll report back in the winter if the snow tires still rub!

I have 17x10's BFG KDW tires, LG motorsports LCA's, and sway bars front and back, and BMR double adjustable PH rod.

Re: Spring help

You definately need to take a hammer an hammer in part of the rear tirewell where it rubs. Still don't know why you are scraping though. Measure your rideheight. From ground to should be 26-26.5 in the front I think.

Re: Spring help

Are you sure the springs are the pro series and not the Sport line series? It sounds like the vehicle is equipped with sport lines from your description.
