Per Eibach R&D:
On 2003 Cobra's their springs lower the front .6" & the rear .9" on a stock vehicle with 3/4 tank of gas.

Be sure you do not tighten the control arm pivot bolts when the suspension is in droop as this will preload the bushings and cause an "over height" condition. Tighten the bolts when the vehicle is on the ground at ride height.

Another area to watch is the indexing of the coil pigtail into the pockets...just a little off can make a huge difference in ride height.
This exactly what the tech told me. Then I explained that I took out the 2 bolts that hold the entire IRS up to put the springs in. So there was no way that I tightened the control arms to much. He replied that "something else is wrong with your car". He was a great help! I will probably put H&R's in the rear now. On a side note, are you going to Coastal Saturday?

 

Hmm, thats intereting. Usually everyone has been very pleased with their Eibachs.

I will try to make it. What time? Where is Coatal anyway?

 

Here is the thread

It is off of 60 in Brandon, like 2 minutes from 75. I have only been there once, so I cannot be very exact. Hope to meet you there.

 

Where are you located? Would you want to meet up somewhere and then drive over there?

 

just cut the springs a bit if they are too high.............

 

This is the car I was talking about with the Eibach. You have the thread on SVTperformence. I will not take a chance and blow 250 bucks plus install. H&R with the SSRgt3's. Sorry MPHgp3, but I just love the look. I had no idea Coastal was so close. It will be nice to have a shop so close.
Hopefully I will meet you guys there and look at your setups. Later

 

I am in Sarasota, I will be taking 75 to 60. Let me know if you can meet anywhere in there.
