I have a buddy that has the Eibach Sportline on his GT with 20 inch wheels and they are VERY close to the fender well.

I'd like some input from members on the pro's and con's of choosing the Sport springs if I just go 18" wheels on my Stang.

Are the Eibach Sport springs too aggressive for most? I see most here go with the Eibach Pro. Reason(s)?

 

I went pro-kit for two reasons:

I needed a nice drop that would level things out, and give my pony a more aggressive stance.

I needed room for travel for my daily driving.

As it is, my pro-kit springs have settled to allow just enough height for the bottom (and my mufflers out back) to clear objects like speedbumps and steeper driveways. I have yet to scrape except for when i had two other passengers in my car.

IMO the sportlines, although they give a great stance, aren't very practical for this reason.

Put it this way - if she's nothing but a show car that gets driven on the weekend, I think you'd be happy with the sportlines. If she's daily driven, or close to, you might find yourself happier with the pro-kit. Plus a nice set of rims and correct tire sizes can easily help fill that wheel well for that desired "slammed" look.

With my 17s on the car doesn't look "slammed" enough. Throw on my 18x9 deep dishers (see sig) and they fill the wheel well WAY more and give the car a more aggressive look.

 

Yea pro kit for DD fo sho. I hear sport lines really change the geometry of the suspension and need a ton more things to correct that. I have the pro kit, daily driver, it is the perfect ammount of drop IMO.

 

How hard is it to do the spring change. I can get a spring compressor, but is there any other special tools? Pretty straightforward install?

I was mainly thinking the Sports would look good with my 17's until I got my 18's but I sure don't want to drag the bottom of the car and knock a hole in my oil pan or anything not to mention possibly prematurely wearing out components of my front end...ie..balljoints, tie rod ends..etc..

 

I would do Pro... My buddy had the sportline on 18's and that thing was damn near the floor. He had the GT500 front spoiler and it was thin as a razor just from DD it. Mainly from the highway that bump when you transfer from road to bridge.

 

The install is indeed pretty straightforward.

All you should need are simple hand tools. And a torque wrench of course...

I do recommend waiting to change out shocks/struts when you do springs. Yes, you're probably gonna want new struts/springs in the future with lowered springs. The OEM shocks/struts are not designed to be used with the aftermarket springs, therefore they will most likely break down quicker than if on OEM springs... which can make your ride go to poop sooner than you'll think.

Also, you're gonna want an alignment eventually for a daily driver. I have around -1.5 degrees of camber on my front wheels, and I know I'm gonna have to swap them with the backs pretty soon to keep things balanced... Camber bolts/Camber plates are a must for re-alignment. Bolts are cheap at ~$30 a pair, versus plates which are ~$220-300 for a pair. Bolts are probably all you'll need for a daily, plates will give you more freedom for adjustment.

 

Thanks fellas for all the much appreciated info! Dan, can you give me the website to where you guys get the Camber bolts/plates from so I can study these options?

Thanks a million.

 

You can buy the camber bolts from tirerack.com

 

Thanks for all the input!
