both are good. Sportlines will drop you a little more but will also have a ruffer ride. For most applications I would say go with the pro-kit but if you want to slam your car to the ground and you have the room then go with the sportlines.

There is not much differnce in the two. The sportline kit drops about an extra .5" than the rpo kit. The car is going to ride rough no matter what springs you use. I love my sportlines and don't have any rubbing issues. You will be happy with either.

I love my Pro-Kit. It's plenty low, I scrape a lot of places...speed bumps and stuff, but I love the ride. Can't go wrong with those.

Depends on where you get it. It usually runs between $239 and $250.

I bought a ProKit, I wish I would have bought Sportlines. Be sure you know how low you want it before you buy them and spend the time putting them in.

I got them for $100 barely used from a member here. You can alwas find a good deal if you look.

There is a thread with the exact spring rates for the Eibach springs, do a search. Search is your friend. As I recall, the Sportlines are actually softer than the Prokits. It's anybody's guess as to why that is.

pro-kit is a better ride.......if your going for looks only go with the sportlines and a proper shock/strut. i've changed my suspension many ways and for price/performance ratio the pro-kit and bilstein hd's are unbelievable.

however for looks and show wise i would recommend the sportlines and bilstein sports.

Sportlines are sexy, esp with 17"+ rims.

I keep hearing about the Bilstien HDs with pro-kits. I've been planning on getting Koni Sports for a while, but are the Bilstiens better than these, as well?

I think that's going to come down to what you want to do with the car - like whether or not it's a daily driver, weekend cruiser or something you only drive when you really mean it..lol.

I've been told that the bilsteins are extremely good and not as harsh as the Konis.

I have yellows with a prokit and most of the usual suspension mods including 275/40/17s.

Turned out for me that the yellows were the best choice because I run the car on road courses now and again and it doesn't bother me to dodge pot holes when I'm driving on the schit roads we have around here.

This car is 95% street and a daily driver. I will bring it to the drag strip every now and then, but only to gauge it's capabilities and have fun rather than compete in the 1/4 or 1/8 mile. I'd rather rip around turns on the highways, owning the import fart-cannon behind me.

koni yellows are the only koni i've ever liked beyond their expensive custom valved pieces. they work really nice but i don't like them off the track.

the bilstein unit is excellent and with the prokit the hd's work very very well where as the sports are match with the sportlines quite nicely.

if i were to change back to stock supension i wouldn't run anything else if funds allowed. unfortunately it's a bit more then say koni orange/red, kyb, monroe, etc. but it's well worth the money in every way.

all i can really say is you will not be sorry....once you have them installed you'll know why you paid what you did.
