[barnoun]

You guys know the rates on these? If they're stiff enough, I might have to consider a set...

 

[barnoun]

He listed the rates: 168R 280F

Oh, sorry I missed it. The rear rates seem good, but the front is kind of soft for such a dramatic drop. Hmm...

 

[barnoun]

Stiffer than Eibachs

True. When I get suspension, I'll be getting something like 450f, 400r minimum though. If the Teins were at least 200-300f, I was considering them. It's alright though.

 

[barnoun]

...I dont get it---The Teins are 280f and you're saying if they were 200-300f U would consider them...

ahhh! Sorry for the confusion(don't know what I was on) I thought 280 was the rear rate. I'd like 450f/400r but that's kind of expensive. The teins do sound good at 280f/168r. Now I am considering them.

edit: Where did you find these springs? I checked on the teinusa.com site and they aren't listed.

!

Hold up, I just checked on the link you gave me, and while they are listed there, the front rate is indeed 168, and the rear is 280. I don't know, but 168lbs/in. does sound low for a 2.4in front drop. What do you think Pat?

 

[barnoun]

Well, the higher the rates the faster the car settles into a corner. It reacts quicker during transitions and is less likely to hit the bumpstops. The main reason why the front rates should be higher is because the car's being lowered 2.4 inches up front. That's a lot considering we have little travel to begin with. If the rate is higher, the suspension will have less of a tendency to hit the bumpstops. There's other reasons why you want higher front/rear rates, but I don't know enough to feel confident trying to explain them(they have to do with higher rear rates inducing rotation and stuff like that). For the street though, that's the main reason(if you want to maintain a somewhat comfortable ride).

 

[barnoun]

What does it mean if a set of springs are progressive?

It means the spring rate gets stiffer as the spring is compressed more, like while in a corner. This is generally not bad for street springs since the ride is relatively soft while cruising around and as you start driving more performance oriented, the ride gets stiffer to compensate in a sense. Remember that for racing linear rate springs are better since it's much easier to predict how the car is going to behave in any given turn, since the spring rate isn't changing while in the middle of a corner.
