I am planing on lowering my 06 GT but am not sure which springs to go with. I am debating between the Eibachs pro and sportline. I am going to go with 18 in rims. Which spring would you prefer and why? I heard the pro is a better ride but not quit low enough and the sport slams it but not as good of a ride. I wanna rip in the mountains and have the car feel like it is in its natural habitat. Thank you!

 

What front end are you planning on going with? I have the sportlines with 20's and the CDC Aggressive and my front end is slammed ... need to be real careful with my setup. When I was on 18's it was low enough but I only had a 1.5 drop then.

 

probably going to keep stock, maybe a cdc aggressive not positive though. I am only going to run 18's for sure tho. The sport line is a 1 3/4 to 2 1/4 in drop, kind of a lot. I heard the pro is a better spring and the sport is lower. I want superb handeling mostly.

 

Once you get to the size of the drop of the Sportlines, you start needing more suspension work to compliment it. The only thing you really need with the Pro Kit is an adjustable PHB, and several people haven't even needed that (though I'm not sure that they've actually measured to see if they were still centered.) The ride on the Pro Kit is great. I can't say what the Sportlines are, as I've never owned them. I think the Pro Kit lowers it enough. Enough for me anyways. It's a noticeable difference, and still enough clearance for daily driving.

 

Is that the pro with 18's?

 

Yes

 

If you're considering the CDC Aggressive then get the pro with 18's. Looking good DarkFireGT

 

Since your goal is handling, your only choice (of those two) is the Pro-Kit. Like DarkFire says, the sportlines will compromise your suspension geometry. Here is another pick of Pro-Kit and 18s.
