Does anyone know the spring rates for our generation civic? All I find online are the rates for the 92-00 civic.

 

Eibach Pro-Kit = 200lbs/in Front & 406lbs/in Rear
Eibach Sportline = 228lbs/in Front & 458lbs/in Rear

 

Thank you! Do you know why all springs and coilovers for the 7th gen civic use more stiff springs in the rear? Wont the over steer be crazy or ride really rough?

 

Spring rates are determined by the car's motion ratio. And, for our cars especially, the rear rates tend to be higher in the front's as a result of suspension design.

 

Ok makes sense now. I have a 2003 with the 15.9? Mm front sway bar and19mm rsx rear sway bar. Would those springs rates be good for a car wanting more neutral handling and I not what spring rates?

 

Those rates are incredibly soft. But, that's your typical Eibach setup, since it's a slight improvement over stock without sacrificing ride quality.

 

Ok what are good spring rates for this gen civic? My mind is still baffled how the rear rates could be so high. On the 92-00 500lbs in the rear would be insanely rough for a dd. I looked at the progress coilovers and they were 350/650

 

It'll depend on your static ride height, what kind of driving you plan on doing, and how comfortable you want your car to ride.

Personally, I've got 11kg/mm (~615 lbs/in) fronts and 13kg/mm (~728 lbs/in) rears.

 

What's your ride height and drivin style with those rates?
Would you consider your ride rough?

I'll be mostly daily driver with some spirited driving I live in the northeast so definitely nothing more then 1.5-2.0 inches.

 

Ride height and driving style? Umm... never really measured a ride height from the setup after corner balancing, so... no clue there. Driving style would be track-derived. I rarely get to drive the car these days due to lack of funds, but when it's got tires on it... it goes to the track. It's not unbearable on public roads, though. I've driven it cross-country a few times.

I wouldn't go as aggressive as I have, just for the sake of it being your daily driver. I'd shoot for a 9-10kg/mm front and 10-11kg/mm rear setup.

 

Do you happen to know the spring rates of the h&r sport springs as well? Id assume that they are more then eibach.
