Question Thinking about an Eibach Pro Kit....help me out

Well i am thinking about lowering my car because i like the look but i need to know some information first. How hard is it to install the new springs? What other mods do you suggest to go with the springs, shocks? What brand? I am not an autocross driver but i do like the lowered look and the better handling. Any tips, info, or suggestions are welcome.

Thanks
Fred

Rear spring are a breeze. Front springs are more difficult.

To replace the front springs you have to drop the entire spring/shock assembly out of the car. It can be done at home (you'll have to rent a good spring compressor) but it's just a little more involved than the rear.

Shocks would be the item you would want to replace while they're out. The stock shocks on F-Body's are terrible. The steps you take to remove the front assembly are required whether you replace the springs OR the shocks so now is the time to do it.

Since you won't be autocrossing, shocks like the Koni single adjustable are a bit of overkill. Most likely something along the lines of a Bilstein HD would be the best choice. My advice is to absolutely change your shocks when you do the springs. The Eibach Pro front springs are a progressive rate spring whose rate varies from 377 lb/in to 600 lb/in. You need a very good shock to control the spring movement. Stock shocks just won't do it.

You have the what most people consider to be the best front bar (except for weight!) you can use and that's the bar I use. I run a smaller rear bar, as most autocrosser's do, but since you don't autocross, that shouldn't be too much of an issue. Possibly once the car is lowered, you MIGHT need an adjustable panhard rod for the rear. It doesn't happen to everyone, but sometimes when the rear is lowered, the axle shifts to one side a little and the adjustable bar will allow you to re-center it. It also gives a little more stability under hard cornering. Just don't use a bar that uses poly bushings... EVER. Mine has rod-ends on both sides. I changed my rod-ends out for QA1 rod ends and it makes absolutely NO noise.

My BEST advice is to call Sam Strano (go to http://www.stranoparts.com ) and speak with him and get his advice. Every fast good handling F-Body has used Sam and his advice to get exactly what they needed for their intended purpose, nothing more, nothing less. He won't sell you anything you don't need and he'll get you EXACTLY what you do. No guessing. He's by far the most technical F-Body setup guy around.

I called, Sam. I told him I wanted better handling and I only use my car on the street. He suggested I use the Koni sa up front, bilsteins in the rear, remove the isolaters, and run a 35mm hollow bar. The ride is awesome and handle great. Without the harshness of after market springs. Good shocks like koni or bilstein HD will make a hugh difference on how the car handles and rides.
