I am looking at both the Eiback Pro-Kit and Pro-system. I know the kit is only the springs.

I had installed a kit on one of my cars back in 95 but found it was a little rough. Looking at the Pro-System it sounds like it would be a smoother ride but is it really worth the huge difference in price.

Anyone that has either of these kits let me know what you think of them.

 

Don't forget the Pro-System-Plus.

 

That is waaaaaayyyyyy more than I want to spend

 

It's only about $250 more than the pro-system.

 

Ya which by the time I pay exchange duty and tax that equals about $500.00 more

 

You could always have it installed in the states, then you don't have to pay any of that extra stuff.

 

First I need to find out what people think of just the Pro-Kit. I'd rather just replace the springs instead of the struts and shocks as well. I don't mind if the ride is a little rougher but I don't want to feel every little crack in the road either since I drive over 60 miles a day to and from work.

 

Have you changed your tires yet? I got the Pro Kit and had 35's on my new rims and the ride was harder, but not spine-jarring. I was driving my car freeway, local streets, etc and the only problem I had was that railroad crossings which once were minor bumps became bone-shakers!

I never raced my car, it was my daily driver (when I was home), so I didn't want it too harsh. The Pro Kit did exactly what I wanted it to - stiffened the car up a little and lower it to a very nice stance. If you keep the stock rims/tires, or have a decent amount of sidewall, then you should be ok.

 

Thanks for the info. I have not changed my tires yet but they are on order. 40 series in the rear and 45 series in the front. I just got an updated price on the Pro-System and nearly pooped-me-pants. $1,040.00 Canadian + tax. Doh, darn near $1,200.00. Looks like I will need to get these in the states and drive em back across the border.

Edit: I think I have decided NOT to go with the Pro-Kit. Sounds like the ride would be no different than the kit I bought in 95. On my way to work I cross 4 sets of railroad tracks.

Who knows. I might change my mind and not lower it at all.

 

I see from your sig you got the SCT Xcalibrator. Noticeable difference? What did it do?

 

Have yet to DYNO the car. I got the tune because I installed the MMR intake kit and my engine light came on. All I can say is I definately notice a difference in the 2,500-4,000 rpm range. I should have it dyno'd soon, most likely after I install the CDC Shaker.

 

Adrenalin,
I put 45 series tires on my pony and noticed a tremendous difference in ride quality, it is more jarring when going accross inconsistent areas of pavement. Let us know which kit you pick, I am interested in getting springs myself. Also, are you planning on doing the install yourself or having it done?

 

I have stock tires and got the Pro Eibach springs. They fit great. Lowered the car 1.5 inch on the rear. I did it myself. But that's the rear. I have not had time to do the front. Have it scheduled at a shop in 2 weeks. A little more work to get them off. As for the ride, I paid special attention before I made the change. I can not feel any difference. I just hated it was jacked up in the back. Looks mean now. Go to www.cardomain.com/id/onebad2005gt and click on page 3 for a side view. Pictures on the left of that page were before. Ones on the right were after. The side view with the window tint is after. Hope this helps.

 

I plan on doing the install myself. A local shop loans out the spring compressors so I can do the front with no problems. Heard it takes about 1 1/2 hours each side. I am use to lifting/lowering jeeps/cars so it shouldn't be too difficult.

Still contemplating on what to do. I think I will wait until after my new rims and tires are installed and go from there.

 

The Pro kit for sure. I would not go any lower.

 

I think the Pro Kit, Pro-System, and Pro-System-Plus all lower it the same amount.

 

You are right, they do, you just get different parts with each kit.
Pro-kit - springs only
Pro-System - springs, struts, bump stops
Pro System Plus - springs, struts, bumps stops, sway bars.

All lower the same amount.

Just each step up is suppose to give better handling. I am just thinking that the Pro-system not only will lower the car but give it a smoother ride than the pro-kit. Then again that is what they claim but I have heard that the struts are stiffer resulting in a stiffer ride.

Now I am hearing about issues after lowering the car regarding control arms, tire rubbing, etc....

I guess I will wait until I put my rims and tires on first, if I can ever get the backspacing sorted out.

 

Any reason you are not considering the Steeda springs? I am looking to get some springs myself and I was leaning towards Steeda.

 

The reason I am leaning towards Eibach is that they have it packaged in different kits, makes it a lot easier when buying then Steeda which has all the parts seperate.

 

I can buy Eibach springs locally whereas Steeda I would need to order to California or something. Also I have found a lot of info on the Eibach's but all I found on Steeda was the problem with the front springs.
