Hey, I'm sort of in the same situation. I know that I would like something thats more lenient on daily driving in houston's streets, so that's why I'm going with the pro-kit. Does any have a gsr with stock shocks? Thanks, Calvin Nguyen

the pro kit has progressive spring rates which the sportline does not.

YEah, sportlines are pretty low, but the ride is excellent. One thing that seems kind of weird is that it looks like I have more gap in the front wheel wells. I dunno, maybe it's meant to be that way so the wheels have clearance when you turn.

that's funny because on my car the opposite was true, i had tucked tires in the front and little or no gap in the rear, but i agree that the ride was nice.

I love my sportlines, i'd never buy another brand of springs. I'm over satisfied with these springs they have just the right amount of drop and excellent spring rate. The ride is sporty and smooth.

This is my car when i just dropped it in 2005

Has anybody owned both Pro-kits and Sportlines on the same car? Is the ride significantly more oppressive on the Sportlines, or is the difference in ride quality relatively minor?

ive had both on my 98 hatchback on the same set of tokiko illuminas. i switched to sportlines cuz i wanted a little lower drop. the ride quality/spring rate feels the same. i love both sets. only thing i dont like about eibach is that they do not disclose their spring rates to the public. its like a big secret or somethng, lol.

I know for the CRX, that the spring rates between the sportline and prokit are exactly the same.

I was dissapointed to learn this. I would have expected their sportlines to have stiffer spring rates for increased handling. And because they are lower, stiffer rates in order to prevent bottoming out. Call eibach and ask the spring rates for your application.

Stiffer spring rates does not always mean better handling. And sometimes you can't go as stiff as you'd like with an OE style spring because they still need to be a specific length to really work. This is why you rarely see 800lb OE style springs, they would be 2" too short.

relax man. no one said anything about 800lb. springs that were 2in. long.

All I said was that Eibach cut corners instead of proprely engineering the two different spring applications seperately.

I was plenty relaxed until you just made that statement. Using the same rate does not make our lives any easier, the springs are still totally different. Our R&D Manager, who is an engineer and professional driver, just felt that those rates worked well at both heights. Each kit was tested on city streets and at streets of willow, I looked it up. I can bet you that *most* of the other suspension companies only do half the R&D we do. They can't afford to, as they don't even make their own springs!

I guess it depends on the drop you want. I have just got the Pro-Kits installed and love the way it looks. It handles only slightly stiffer than stock (and I'm probably going to turn my adjustable shocks to a bit firmer setting). No problems with bottoming out - but I'm getting a bit of rubbing so haven't flogged it yet until I get that resolved.

I have similar situation. I have a 00 civic and have decided on either the pro-system or sport-system. For my car eibach says a drop of 1.5 in front and 1.1 in rear for pro / and for sport its 1.6 for both. My only concern is its my daily driver and never sees track time so i dont want it to be a problem during snow season or going over speed bumps. never lowerd a car before so I dont know how significat 1.6 is.....i am leaning toward the sport-system because its a even 1.6 drop in front and back....anyone had the sport system on their car? not jus the springs but kit?
