Trying to dig up some spring info

[nametakennow]

Like the title says, I'm looking for some info on spring rates and not having much luck. I've checked around a bit on Google and a couple boards to no avail... here's the comparison:

H&R SportsEibach Sportlines

Not like it matters, but either would be on Koni Yellows... on a 2001 Sentra SE (SR20).

Yup, you know what's going down .

its in the suspension faq in the w/t/b/s forum, but ill give it to you anyway...

H & R SPORTSpring Rate - F : 2.0~2.08kg/mmSpring Rate - R : 2.5~2.6kg/mmRide Height - F : -1.3"Ride Height - R : -1.3"

EIBACH SPORTLINESpring Rate - F : 1.92~2.0kg/mmSpring Rate - R : 2.4~2.5kg/mmRide Height - F : -2.2" / -1.75" (test)Ride Height - R : -2.1" / -1.75" (test)

Well now that you have the specs....I'll chip in and say my buddy has the eibach's on his 01 Sentra SE and loves them.

See, that's where it gets interesting.

Those numbers are for an S13 or S14.

Now, you wouldn't think they'd vary much from car to car, in essence meaning that the H&Rs are generally slightly stiffer than the Sportlines. However, I have found one other page with this sort of info, but it refers to VW Golfs/Jettas, which are more similar to my car in terms of vehicle type and what you ought to do to get the most of the car.

Here's the link - http://forums.vwvortex.com/zerothread?id=602321 (numbers are in lbs)

Suddenly, for the life of me I can't find the specific numbers in there for the lazy. I'll keep looking and edit when I find them.

Basically, the fronts match up (about) with those numbers you showed on the S13 in the sense that the Sportlines are slightly softer. However, the rears on the Sportlines are a good bit stiffer. I figure that's to combat understeer.

For the life of me I can't find numbers for any B15 - QG, QR, or SR powered.

Oh, and the drop is different. the H&Rs supposedly get 1.5F 1.4R (I think it's closer to 1.4/1.3) and the Sportlines supposedly get the same 1.5/1.4, although I think that number is a little off as well (the car actually being lower by a tenth or so).

edit: Here's some BMW numbers I found last night - http://e30m3performance.com/in...2.htm - I'd think that, being a sedan, that'd be slightly closer but hell if I know.

It says: H&R Sport - 185F/380REibach Sportline - 160F/455R

I know that the yellows are really the key part to the suspension, but I'd like to get the springs right too. Every ricer around here runs Eibachs, usually Sportlines for the drop, not the better numbers. I really wanted to be different, but if the numbers tell me otherwise, and since the Eibachs are (slightly) cheaper (probably because they sell many, many more), well.

i installed rsr race springs on my koni yellows this weekend, and so far they feel incredible, but i havent tried them out with the azenis on yet.

Koni YellowsGC Coilovers (~350 lb. front - ~280 rear spring rates)

Yep. Good stuff. And you can get Koni to valve them for the springs specifically.
