TrueBlue03 said:roush springs lowered the rear about 1.6 - 1.8" i'd say. (i do have a heavy sub and box in the back tho) Almost as low as the sportlines SHOULD sit. they worked well, but they dont seem as stiff as sportlines. and they are still pretty low... if i could do it again, i'd get steeda sports in back to not lower it as much.
Here is a pic with the roush springs in.

not all sportlines sag, it's due to low quality manufacturingTrunkFunk said:Look closely at the wimpy rear rates of the Sportline Springs (140-295) ...
... of course they are going to sag.
Sportlines are only great in a Fox body, more specifically a notch.
H&R SS is what you need for a 2" drop on heavier steeds (99-04).
The healthy spring rates will ride 'sporty' as well.
man i jacked up my car, popped the back wheels off and went at the fenders with a gigantic metal hammer and a huge pair of pliers. LOL!!!!02GTRX said:What did you roll them up with? That what I want to do but Im afraid it'll bend up another part of the fender

I've had sportlines on 2 cars for over 4 years, no sagging. there goes that theroy, now poorer manufacturing where they aren't making them with full progressive lb rating they're suppose to be rated at will cause itTrunkFunk said:Eibach's manufacturing quality isn't low.
It's the spring rates and the weight you are placing upon them.
140lb/in makes a progressive spring soft on the first few coils.
Ad weight to these and their memory is going to goover a quicker period of time compared to a higher rate spring.
It's not poor manufacturing quality, it's poor salesmanship and poor choice of spring for the car.

trailblazr81 said:Then why dont cars with softer ride and low spring rates sag within a year? Ive had cars with low spring rates that would stay at "stock" height for years. And even if this were true why would Eibach list on their websight a "Million mile warranty" if a lower spring rate would cause them to sag over such a short period of time? And why is it others have had Sportlines on for 6 months and they sag and Ive had them on my car for a year and a half with no problems? Its either low quality control or just a poor product that they are selling.
see sigTrunkFunk said:I have no idea what exact 2 cars you are referring to.
I'm not saying that applies for all cases of lower rates but it's not always true, 4+ years of my sportlines proves that, my car isn't a show car and has seen plenty of hauling days including bricks/concrete and other assorted heavy stuffTrunkFunk said:I realize dismissing spring rate helps drive your point ... no wait, are you dismissing spring rates or not?
Is a 140lb/in - 295lb spring good for the rear of a heavy Stang?
Seems a bit soft to me ... as rated, aside from what actually gets pumped outta the plant.
me owning proof isn't evidence?TrunkFunk said:Companies do go through transitions and quality can suffer, yes that does happen as we are all aware. I'm not disputing that possiblility, I just do not see that evidence presented here.
I don't run around with theroys, i go by facts, i don't feed guessing games, If I know something I say it, I'm on this board to help people out just like you doTrunkFunk said:Spring designs can also be revised and in your case above, it's possible the springs you received were the proper rates for the vehicles equiped with them ... Then again I don't know what truth there would be to any of what you said above, nor should I expect you to take anything I say as fact.
We both shall draw our own "theories" based on the evidences we have before us, right?
I wouldn't doubt itTrunkFunk said:It is also possible that some may be experiencing the affects of outsourced manufacturing to China or other turd-world countries? Who knows, I have no idea where Eibach's spring plant is currently located and or what materials and methods are being employed ...
I haven't been to the 5.0 side lately so I have to take your world for it, don't really have an input for yaTrunkFunk said:I do know that people more gripped in the Fox side of the Stang universe are not experiencing a proplem with Sportline sag on any sort of large scale (no manufacturer is 100% on). I'm not ruling it out as a possibility, I'm just saying the talk about it happening is not out there.
I suppose we would hear such gripes if guys were installing the springs in a GT vert or other heavier bodied model, but we're not hearing it.
TrunkFunk said:Who knows, you could be right, but the buzz I hear all the time in 5.0 company is that of only good things about Eibach springs.

........ sounds like you guys have a small regiment
HoustonGT said:TrunkFunk, i really don't see what your point is.
HoustonGT said:If the damn springs were made for a 99-04 GT's by Eibach, then how the crap is it our fault for choosing the wrong rate springs for our cars? These Sportlines were designed for our "heavy" Stangs and should not sag for any reason
