I have the Pro-Kit on my Civic, and i love it. Eibach makes awesome springs.

one question i like to ask...i notice for my model they make it stiff in the front and soft in the rear. what will i expect out of the vehicle when i switch to ok in the front and stiffer in the rear?

thank you
Vinh

I'm really happy you are making this thread. IMO S2ki severly lacks in this department. Check out 350z-tech http://www.350z-tech.com/zwiki/Part:Springs

And the S2k has been around for how many years and we don't have anything like this. Ohh well. Anyway, I figured I'd help contribute to your post.

Anybody with price info please post where so it can be updated

Also, to the OP we differed with the Tanabe GF210, I ended up going to Tanabe's website and found the same 4.5/5.5, just wondering where your info came from. I don't want to be giving out the wrong info.

This will continue to be updated....

 

Why havn't these been listed??
- SWIFT SPORT MACH springs
1.0 rear
0.8 Front

 

eibach pro kit with koni shocks on lower perch. i've been very happy with the ride quality and the drop. i keep the shocks all the way firm in front and inbetween soft and firm in the rear. i would recomend this combo

 

Bump for folks who can't find this thread!!

 

^^We need a suspension sub-forum in with this forum.
