Spring rates
I'm searched out... Maybe someone can school me... I'm looking for spring rates on the Eibach Pro-Kit and Ground-controls...
I don't intend on tracking my daily driver so I'm looking for something to eliminate some wheel-gap, and keep the same ride.
Everyone's opinion is subject to their perspective and perception of "ride quality". So, I figure the best way to figure this for myself is to study spring rates.
(I suppose "progressive rate" springs are not something typically listed as a static rate.)
Here's what I've found: (and if anyone can contribute please do)
OEM Springs: EDIT
NOTES: http://www.s2000.com/2004.php
OEM:
00-01 - Fr: 218(3.9) - Rr: 291(5.2)
02-03 - Fr: 240(4.3) - Rr: 230(4.1) <<est.
2004 (this is a tough one...)
If calculated against 00-01 rates (based on quote above)
Fr: 233(4.16) - Rr: 262(4.68) (218 - 7%= 233) (291 - 10%= 262)
If calculated against 02-03 rates
Fr: 256(4.57) - Rr: 207(3.7) (probably incorrect)

"In terms of spring and damper tuning, up front the spring rates have been increased by nearly 7%, while in the rear they've actually been softened by roughly 10%. Damper rates have been adjusted accordingly. The front stabilizer bar is unchanged, while the rear bar has been reduced in diameter by 1.8mm."

FWIW, I have 380's all around... I don't believe they are too harsh. My car is not exactly a daily driver, but I have put on 47k+ miles on her in just under two years. I'll be using 500/550 next time at the track though.

I'd prefer to keep the stock feel, but get the impression that if I lower it an inch, and keep the same "rate" I run the risk of bottom-ing out the shock.
-true?
Would it be unreasonable to get GC's with stock rates?
240(4.3) - Rr: 230(4.1)
Another thing;
What's up with the rear rates having bias over front on certain models?
what's the point there?
thanks!

Hey, does anybody know the spring rate of H&R springs?
With the spring rate being greater in the front, (ie.Neuspeed,KG/mmSport) ,the intent is to dial out oversteer.
