I just had a quick question, I have a 2000GT, and I am between the pro-kit, and sport-line eibach springs. I know the sport-line lowers the car more, I wanted to know if in doing this I would have to add other goodies such as cast and camber plates etc... Or should I just stick with the pro-kit, does it lower the car a sufficent amount? I appreciate the info.

The Sportline's are about a 2- 2.5 inch drop, which in most cases is not the best thing for handling or ride. The Pro-kits are about a 1- 1.5 inch drop, and they make the car a little bit firmer. Camber/Caster plates are not required but it won't hurt to have them if you have the funds. Everything you need for the springs should come with the kit.

When you lower your '86-'02 Mustang you change the tie rod angle from the rack to the spindle. This change incorrectly alters the steering geometry creating what's known as "bump steer." To eliminate this problem on lowered vehicles, we've created these offset steering rack bushings. These bushings relocate the rack in the chassis thus restoring the original steering geometry.

JC - these are a must-have with lowered suspensions...

If you only lower your Mustang 1"-1.5" then bump steer is not a problem.

Bump steer becomes a problem when you lower 1"-1.5" and then put a large amount of caster into the alignment. Or go more then 1.5"

I do not recommend more then an 1.5"

I put the pro-kit in my '98 and they balanced the chasis better than the stock ones and the ride is still good. Which was a big part of getting these springs living in MA, BAD roads. I would recomend the caster camber plates! It will take the nervousness out of the car at speed if you put max caster into it. Just brace the car before you change springs, less rattles in the future.

I HIGHLY reccomend Steeda Sport springs. I have them and my car handles as if it were on rails. I also installed the Steeda X2 balljoints to help with correcting the steering response and handling.

IMO- best thing i have done to my car yet.

1.5 max and DONT USE offset rack bushings.

Get the CC Plates and the Steeeda X ball joint, night and day difference.

hmm.

i use eibach pro-kits on my cobra and the steering geometry did not change. if you do lower the car more than 2", then i can see a need for a correction for the bump steer.

the biggest factor will be how streetable you want your car to remain. pro-kits are very good at dropping the car slightly and maintaining good drivability. used in conjuction with good aftermarket struts/shocks, they can be a great improvement in the car's handling.

the sport-line springs are a race only application. i have seen some street cars with them installed and the drop is nice, but the ride may become too harsh to be tolerable.

Sportlines are FOR LOOKS more than performance.
Best Racing springs are always linear rate.

[dmark101]

i disagree about the sportline springs, but yes, linear rate is superior for any type of road racing.

i would go with the pro-kit. A friend of mine has a 2000 v6 mustang and he has 17" y2k cobras and the eibach pro-kit and it looks perfect. Any lower and it wouldnt look good at all. It dropped it about 1.75 inches in the front and 1.5 inches in the back. I think that any lower would just be to low.

I have done this mod and it is the best thing I have ever done to my car. I love the handling. It is slammed to the road. I have never road raced it........per say........they have a leauge around here and I am gonna have to go out and spin it. Ill let you know when I do.

Till then, friends who have rode with me say the turning is very impressive. Only experience in out handling was as follows.

My son and I drove from Louisiana (2 summers ago) to Pocono, PA to see a Nascar race. Of course it is off an interstate about 3 miles in a "country" place. On the way home that evening I got behind a vette. On the 3 mile ride back to the Istate. Cops had the road coned so that there were 3 lanes going to the Istate. He all the way...bumper to bumper crawling....he would juice it enough to squeak the tires. WHen we got to the Istate we were going around the onramp (the bridge over the istate loop type where you do almost a complete circle on to a 5-10 degree inclining road) he lagged bigtime to let the traffice in front of make it to the Istate then stomped on it and took off. Being well familar with the handling since I love these curves and have run them hard before (and being big-headed since had brand new rubber) I gave chase. As we hit "turn3", the tightest turn of the loop near the straight, i snuck a nose under his right side with tires screaming but holding good. Boy did it freak him out. He moved over and did 55 and let me go.

Idiot bowties, just cause they pay more they think they get a better product.

Later,

Emery

oh....ps. Since we were roadtrippin I had my car smaked full of camp gear and coolers and such.

Sorry got excited rembering that story,

I suggest not slammin it to the ground whatever manufacturer part you use unless it is a race-only car. Use race-only parts for this purpose only or you will be very uncomfortable.

I already from my lowering and stiffining of my suspension have to replace the bulbs and covers from my license plate. They crack and break and I replace them about once a year from road hazards where I guess my decklid hitshard on the bumper and the vibration damages them.

The Eibach Pro's are an excellent daily driver street spring. You will get nice handling/ride from them for the street. If you are looking to the track I would look at HR linear rate springs

[bob8797]

Ok, don't blame me if this isn't up-to-date because I picked this up off of the internet....

Springs.... drop..... rates F/R

Eibach ProKit cpe.1.5".460-570......200-250
Eibach ProKit vert.1.5"460-570......170-310
Eibach Sport...........660..........260
Eibach Race............700-850......200-260


Yeah, the 1-1/2" drop is really all you should go unless you want to make other adjustments to the front end.. and you don't mind bottoming out occasionally.

As was said, the Prokits are good all-around daily drivers springs. Slightly stiffer than stock.

Here's an SN95 on Prokits:
