Anyone know this? I know they are progressive, but any numbers would be good to get. Thanks-

 

Free bump!

Eibach doesn't publish their spring rates. From what I've seen of what people have found about other applications, it's been approximately the same as stock in the middle and 1.5 to 3 times stiffer than stock on the outside.

I've been dying to know this as well, though.

 

Yeah, same here....

 

OK, noob question then- Whats the Stock (SE) rates???

 

I have them springs, Ill see if its written anywhere on the box or something when I get off work today.( 8 hours left ... ewww)

 

131 lbs/ft front, 200 lbs/ft rear (both linear).

Squishy squishy.

 

Yeech! Thats hard to believe! (did you reverse the front/rear?)

Either way, its no wonder I was doing this gnarlyness in autocross! (Still winning I might add!)

 

Just repeating what I've read. I always assumed that the reason for having bigger rear spring rates was to ensure an understeer bias.

 

Sorry d00d, didnt mean to imply that you are whack. Just amazing that every performance spring rate is set to have front at higher rate than rear and stock does the opposite.

(Plus, Im used to dealing with little mix-ups like that from work too.. instead I am guilty this time.)

Cant wait for the K-sports! Gonna be a rockin but not rollin scene!

btw- I am hoping for your knowledge and expertees in the install... since I am a n00b and we are getting our stuff around the same time. For instance:

if I get the alignment set for, say, negative 1 degree at 1 inch of drop, would I get more negative camber if I dropped my ride at the track, say to 2.5 in?

Would love to hear your info-

 

Haha, don't worry, no offense taken. It's just as likely that my source could be mistaken here anyway.

And I did make one mistake... Softer front springs would increase front grip, which would increase oversteer. Stiffening the rear would balance an understeer bias, not increase it. Our cars are really front heavy and have really sticky rear ends, which is a recipe for nightmarish understeer. It makes sense in that light that we'd have softer front springs to keep things more neutral until the limit.

The RSX Type-S also apparently has a stiffer rear. It's got something like 200 lbs/in front and 400 lbs/in rear, which also makes sense IMO... that car has an even more urgent need for neutral handling, from a marketing standpoint at least.

d00d... rockin but not rollin... f**kin excellent. That needs to be a damn window sticker or something, right under the K-Sport logo!

Front suspension = MacPherson struts = strut is mounted to wheel hub assembly, so you'll get more negative camber in front if you lower the car at the track. Rear camber shouldn't change with lowering because of the beam setup, which keeps the wheels perpendicular to the beam at all times.
