Augusto what do you have to loose? just cut one coil off and see what happens.

you may end up liking the little added stifness.

if it drops too much just add shims, pretty easy.

Ghetto Jet I found out the real problem.

When the 03/04 Cobra came out Eibach just just told vendors to continue using the existing springs for 99/01 Cobra. Anyone who bought them ended up with a jacked up rear end. They just don't give the right drop on a Cobra like mine. It wasn't until a few years later that they designed springs specificly to my car. However Eibach made little effort to inform vendors of the new spring and people to this day are still sold the incorrect kit in some places. My Eibach tech didn't even know what I was talking about, but I've done all the reasearch and them some. I have both part numbers. My car has the wrong springs on it. I'm now waiting to see if Eibach will swap me, which seems unlikely. But also in my searching I've found that Eibachs quality is so so and my best bet is with a brand like H&R. But if I can get Eibach to send me new springs I can sell them and recoupe some of my money.

Here you can see my gap, i can put my whole fist in there.

Old Rotor Flap Before heating the springs with a torch, get a bunch of guys together and a couple of cases of beer. Turn up the boom box, drink and laugh at the Darwin Awards on the web. Make one future ex-friend the designated dialer... tell'em to punch in 9-1 and the phone and wait. Get under the car with your torch. Fire it up under the car.

Before ruining the first spring, inadvertenly pass the torch near the gas tank and that tiny leak you didn't notice. About now, the designated dialer should enter the second 1 to his phone and run like hell. The last thing to go through your mind will either be the gas tank and contents or thoughts of making this years Darwin Awards list.

This is intended only to tell you not to heat your springs - all around a bad idea.

Ghetto Jet I want an inch from the rear only sqzbox, to level it out. I didn't put the springs on, I bought it this way. But the front is only about 1" lower than stock. I would almost consider putting the stock springs back in but it does handle better than a stock one. I know it will end up doing a auto X with my friends and I don't want to get killed on the track too bad.

sqzbox If you hurry, you can use it to clean the snow off the drive this winter!
It's all funny, back in the 60's and 70's, everyone put air shocks on their car's
to keep the underside of the car from dragging on stuff like speed bumps and
stuff. I've driven semi's for a living for 27 yrs. and don't have enough fingers
to count how many times I've seen a lowered car bust the whole front clip when they smacked a recap semi tread in the middle of their lane on the interstate. Your setting yourself up for a big PITA if you go much lower.
I've also worked in many tire stores and gas stations (where they used to work on car's) and some of them you couldn't drive over the lift racks to change the tires, or hook them up on a wrecker. Had to send a roll back and they still dragged being winched up on them. I think the fiero was one of the worst. So.... my point is, do you really want to go lower? Think about it before you commit. Personally, I would want a little clearance under there especialy in your geographical location. PA is not an undercarriage friendly state

bentwings I guess that now that all have said that torching the springs are a bad idea, go ahead and torch the springs..... you will have to replace them anyway. That way you can become learned (learn ed) and understand why we say don't torch the springs, get the right ones to begin with.

I say this with a little humor as I would bet that each of us have torched the springs at least once and thus become educated. haha

bobjob for each 1'' of spring drop you go,,,,, it will settle another 1/2'' over time... and they will drop at different rates.. plus they will break sooner or later.. what kind of fool are you??? with a car like that,, SPEND a FEW dollers and do it right!!!!!! I've done it before on my $300.00 cars that i was lowriding,, but they were JUNKERS...

I would of said no before because it seems a coilover kit is $1400-2000. But there are coilover conversion kits for my stock Bilsteins that are around 600. I'll have to do more research.

Jake_Dragon "I" would cut the springs, I have done this with several cars without any issues. Don't cut too much as you can't uncut a spring, don't let it heat up so cut fast. Round the end of the spring so it looks like the end you cut off.

Ghetto Jet Damn you ericnova, now i'm convinced it should be done the right way.

ericnova72 [QUOTE=Ghetto Jet]ericnova- thats what the jack is for, it stops it from dropping too far. And as far as I know if I use a center coil it's shouldn't throw off the spring rate because the center coils don't really have any give to begin with, its all the outer coils, which is why I didn't want to cut one

No, the jack won't help, it will stop the car body, but remember that the spring is preloaded into the mount, the rest of the spring's tension will continue to collapse the spring but you will have no way to visually see it with the body stopped.

You won't find anyone who will tell you heating is acceptable, there is no "Easy Button" for this job. Do it right or you will be doing it later, heating the spring in the middle is inviting catastrophic failure(breakage). That's not going to help the sheetmetal when the suspension drops at 70 mph on the freeway and puts you into the cement center divider.

$20,000+ car but you can't replace a $100 spring??

1ownerT- cutting stock springs usually doesn't hurt much because they are softer to begin with. From what I've been told cutting stiffer aftermarkets is not a good idea. As far as thinner isolators I've been told using a piece of heater hose is my only alternative.

sqzbox, just the rear needs to come down. I put a pic at the bottom so you can see what I mean. I'm running 315/35/17's and they are about even with my 275/40/17's in the front. However my prefered Nitto street drag radial doesn't come in many sizes.
