Eibach Pro-Kit

Anybody here who uses an Eibach Pro-Kit on a Firebird Formula 350 with WS-6 Sport Suspension?
How much does it lower the car,if at all?
I understand that the WS-6 springs are about 1/2 inch shorter than non WS-6.
The Pro-Kit lowers about 1 inch,as they say,so on a WS-6 car the lowering will be only 1/2 inch,right?
Any comments are welcome!
How about the APEX 100-3000 spring kit,any expieriences?

Yes, Mine is a 88 trans, 350, WS6,. Installed the eibach pro kit and KYB
shocks and struts.
The car looks the same. Rides and handles a hell of a lot better. However,
the shocks, struts and springs were worn
out. I got the car new in sept. 1988.

I am happy.

If you get Eibach springs,get them in Europe where they're made-a hell of a lot cheaper,same goes for Koni stuff which as you probably know are made in your country.

Thanks,
For Erictheviking: I tried Eibach Germany,they're telling me they can't suply me springs for USA cars.
I have to order them in the States.
How about that?
And yes Koni is Dutch,but after having so many problems with koni on several cars and bikes,leaking,paint coming of etc. I'm not so sure about the quality!

I used the pro-kit on my 87 trans am. The car now sits a little lower, maby 1/2 inch or so. The ride is a lot stiffer now but the handeling is 200 % better. If you want to lower youre car and improve handeling, GO GET THESE SPRINGS.
