[2fly4nysi]

Recently installed the Eibach ProKit. Very happy with the drop, 1.2 front and 1.0 rear.

[CivicEX]

anyone have before and after pics of their Si with eibach pro lines before and after the install?

[Juice2Boost]

how accurate are these spring rates...cuz i can see some of the ride heights are not right and i dont want to base my decision on wrong info

[squidmaster]

neuspeed springs arriving today and installing today =D

Im kinda confused, looking at the spring rates im guessing that i can buy tanabe springs and not have to wory about stock shocks goin out? Since their pretty much the same linear/progressive?.....

No you will still have to worry about it because the springs sit lower the shock is not valved properly will also sit lower than the stock springs.

would the neuspeed race spring which drop it 2.0 all around be to low for 18x7.5 rims

Eibach Sportlines FTW!

[Jason0911]

So does anyone have the eibach pro kit on there coupe..?I just order some and wanna know how they ride..

[MannyP305]

^not that i know of, but IMO the majority of the coupes that do go with Eibach get the Sportlines. The Pro-kits are mainly seen on sedans.

[Jason0911]

Ya I got the prokit cuz of the body kit I'm getting..didn't want to drop it that low..

[MannyP305]

^which bodykit?

[Jason0911]

I'm pretty sure I'm getting the raven..

[MannyP305]

^nice

[manyak_si]

does this mean the higher in. lbs the spring has..doeas it mean it's stiffer?..

[paolo2k2]

yes...if it says 500 lb/inch spring rate...that means it takes 500 lbs to compress your spring 1 inch..

Part Number----4H913

Both the Coupe and Sedan shares the same part number and also the same spring rates.

The only difference between the two is the drop height due to the weight difference for the coupe and sedan.

I have Neuspeed Sport Springs and I recommend them. They work great and drop the car 1.6" to give a much more aggressive look to the car. Nice and stiff too.
