Eibach pro kit or steeda sport springs. I like that the eibach's go a little bit lower, but I dont no spring rates, are they both a streetable spring, one better for launches and such, anyone a better ride? I looked into h&r but i dont want to buy s/s also, I just want a lower look but dont want to spend $1000 just for it to be lower, so i figured springs and c/c plates. what you guys think.

Here are the spring rates for the Eibachs and Steedas that you are looking at, the first two numbers are for the front springs and the second two numbers for the rear springs. I also included the rate for the two popular H&R springs.

Eibach Prokit -425-530; 200-300
Steeda Sport -650; 200-250
H&R Sport -490-575; 250-285
H&R Super Sport Coupe -700-760; 275-300

As you can see the Eibachs have the lowest spring rate and the H&R ss with the highest. All of them are streetable, just depends on what you like. I think you should upgrade dampers though. If your gona do it might as well do it right. You may not even need c/c plates depending on the springs you choose. And this belongs in the suspension section, I'm sure the mods will catch it though.

What is stock? What about Ford spring rates?

I used the Ford Racing "C" springs, didn't need caster/camber plates to get it aligned. After the springs settled its a little over an inch drop. The C springs a really stiff though

Pro kit is pretty close to stock but progressive. I don't think it's enough spring for as much as it lowers the car. I also don't like to see cars not on coil-over conversions sitting that low. It's counter productive. With conventional springs you should normally stick to about 1 - 1.5" front and back.

Steeda Sport is a pretty firm but manageable spring. I like em. Definitely need a shock upgrade though. These are basically C springs.

For most people looking for just nicely lower than stock but with a decent ride I like F springs and Tokico Blue dampers.

Replace stock struts and shocks with tokico blue's or illumina's with any of the springs you're looking at. CC plates are great if it makes it into your budget on this round. Otherwise wait till the next round of mods and replace the shocks and struts first. It's ok to run stock plates but you should expect possible increased tire wear until you get a nice tire friendly alignment on it which may require plates.

I like the look of the lower cars...however with longtubes I didn't want it to be so low they would scrape. So I went with the steeda sport springs and tokico HP's (blues). This setup rides pretty much like stock maybe slightly stiffer. You should definately get shocks/struts though. I did not get caster camber plates and was able to have the car aligned properly without them. I'm not 100% happy with how low it is but it is good enough for my daily driver. My measurements right after we installed them came out to 1" front and 1/2" rear. I believe the rears are progressive if I remember right so it may be closer to 3/4" after it's all said and done.

yeah my ford racing springs aren't too low for everyday driving, but I do sometimes scrape my chin spoiler or even sometimes my stock cats.

Thanks for the replies, well im either getting ford c spring or steeda sport spring, are they basically the same spring? seems like it to me.

Another option would be to find a Ford Racing Suspension ans Performance Kit. It comes with Springs, Sway Bars, and shocks and struts. I bought the kit for $300.

This is the setup that comes with the Mach 1. It is very streetable, a bit more agressive then stock, and will lower the car to get rid of the 4x4 appearance w/o looking "lowered". Expect about a .75 to 1.0 inch drop.

The Mach 1's handle a lot better then a GT and for the price....if you can still find a kit....it is a steal.

However, if you are looking to build a drag car, or want the sunken-in, lowered look, these won't be the springs for you.

what would happen if I put on steeda sport springs and thats it, no aftermarket shocks or struts, just a bad ride or would it ruin something?

01FR500

It would be a poor ride and ruin the dampers after a while.

cuz the thing is I do not plan on keeping my car, but i want it lowered for now, i just dont want to pay $1000 to have it lowered an inch or so cuz i wont be keeping it, thats what sucks.

01FR500

If your not keeping the car, then why lower it? Kinda seems like just as much of a waste of money on springs as it would for a springs and dampers. Unless you plan on keeping the springs when you sell it, I don't even see the use in lowering it. How long are you planning on keeping it?

If you just want it lowered, don't plan on keeping it, and want to be cheap, then just cut the springs that are on it. Other then that, then don't do something just to do it. And if you do, do it right.

I agree, I had the Eibachs but it was a little to low. I liked the look, but is scraped to easy on the roads around here. So I changed to the Mach 1 springs, it's a much better ride. Also I had the tokico blue shocks & struts on for both installations.
