I've searched and I don't get it. Sportline is lower but softer. Prokit is not as low, but more firm.

I hear (read) what you are saying, but seems to be opposite from practical thinking that by being lower, you have less suspension travel room, so the springs have to be stiffer.

Example.

HR Race springs is lower and stiffer than HR Sports.

Is there something I'm not getting with Eibach?

 

I remember reading on here that someone called Eibach and was told that the Sportlines are definitely stiffer than the Pro-Kit.

 

sportslines=worse ride,handels better lower drop
pro=better ride then spors,handels decent and not as low of a drop

 

UGHh why cant we have the best of both worlds.

 

Sorry man, the Pro-Kit is the better ride quality and better performing spring out of the two. The Sportlines are only for looks.

 

I mean, my ride quality is almost identical to stock and I have sportlines. I guess since the pro-kit doesnt lower the SS at all it could offer the better ride of the two, but if I buy springs to lower my car, I want my car to be lowered. I cant say much about the pro kit, Ive never ridden in a cobalt with the pro kit, but I can say that after 35000 miles, Im pretty happy with my sportlines.

 

Are there numbers on the Spring's spring rate?
