ok thought this would be a good one for some tech in here...

spring rates we all know they play a major factor with how a car performs.. share your thoughts,ideas and spring set ups...

my Buddy Clubs have 10F 10R
my Function Forms have the standard 10F 8R

considersing going 10/10 again even maybe 12/12 .....

 

if you are going to run that stiff of spring rates on the street, i highly recommend getting swift springs. they are much more bearable because of the design and material they are made out of. they are much more linear springs that have their rate measured from 20-80% of their stroke unlike a lot of other coilovers advertise.http://www.swiftsprings.com you should check out their website and learn about them.

i currently have spoon dampers /w swift mach springs that have rates around 5-6kg front/rear .. eventually i'm going to get the spoon adj coilovers with swift springs 10kg f/r. anything past 10-12 on street is overkill and not worth it unless you track your car every single weekend and daily on the weekdays. unless you like your guts rattled around daily

 

yea i knwo about Swift.... they are great springs... and i dont want to say anything but swift spring are the choice for mine if i decided to change the rates again...

 

I have 8k zeals in all four corners. Im pretty sure swift makes the springs for zeal/endless.

I personally feel my 8k zeals are stiffer than the 10/12 tein flex I had before.

I want to get a better set of coilovers though with higher valving so I can run a 14/14 or 16/16. Possibly arogasta or j's. I cant justify Motons for a street car.

 

how do you like the 10K all around spring rate S@nt0s ? whats your other suspension mods?

im considering get a BC RS as well, but dunno if the 10K all around spring rate suit my need.if not, i will get a swift custom rate spring and match my setup.
i have only spoon front tower bar and a UK spec alignment on my 00 AP1 now, but im getting cusco 32mm front sway bar, spoon front x brace and spoon rear lower tie bar. what kinda of spring rate do you guys recommanded? the main aim is track use, and i dont mind stiff

 

MaskedAP1,
the 10K is kool with me man.. on days im moody i just set the struts soft.. but im usually 8+ on the f/r's.....
other then the coilovers i have a safety21 4 point with harness bar... i plan on getting a X brace and thats pretty much it i think....

 

Get a set of 12s and a set of 10s from Swift, and play switcharound. The BCs damping curve is on the stiff side, so I'd try 12/10 first and see if I have to stiffen up the rear.

Rear-biased stiffness is covered, and not recommended.

 

but im not on the BC's no more.. but the functions are on the stiff side as well....

this is just a open dicussion for everyone to share their rates adn ideas...

 

Spring rate has to match shock valving, chassis weight and balance, and tire specs. Even with 50/50 balance in our car, 14/12 or 13/11 is a common recommended spring rate. Running equal front and rear spring rates usually makes the rear end unload faster, adding to the snap oversteer problem.

as stated above about the swift springs.. Function form will now offer the swift springs with the set up... so i need to upgrade now!

yes that is so!
im considering a 12/10 possible or 12/8.. with the 8 rear it may help settle it.. or just stay 10/8

 

12/10

We get more brake dive than accel-squat, but 8 is too soft.

i guess no one else likes to talk suspension.....

 

The e-racers post but don't have real world experience. The real-racers have experience but don't post. That leaves it to us back-yard mechanics.

yea we are in the happy medium.... track and street ******..... hoping to make a track session this spring with the S.... but until then killin canyons and on/off ramps

 

I been waiting for your *** to track with us man. Get a clutch and lets go.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Me on S2000 Turbo &raquo;</TD></TR><TR><TD CLASS="quote">14) Returning to what happens on the track - a rear stiff car will unload the inside rear faster than it unloads the inside front. At some point all of the inside rear weight has been transferred to the outside rear. A rear camber setting is selected so that at the terminal roll angle of the chassis sufficient grip is generated by the outside rear alone. This is typically achieved on our cars at something less than the camber required to generate the maximum potential rear grip. As the outside rear decambers in roll, and converges on its terminal camber, it is generating greater and greater grip - both as the vertical force increases from weight transfer, and as the dynamic camber improves. At the kind of rear spring rates common to both NA and JDM setups, dynamic rear camber change during rear weight transfer in pure roll is approx +1 degree (decambering). In any case the front decambers approx 50% faster than the rear in pure roll while all four wheels are on the ground. Since we rarely have pure roll without pitch effects we should note that the combined effects camber curves are a more complex story that must be examined in cases. Most interesting among these is drop throttle behavior. The rear decambers fast in combined roll and droop. This points to the usefulness from this perspective of high rear spring rates in general as common to both setups. Generally speaking, as we converge on max lateral acceleration we converge on optimal dynamic camber - assuming we're doing our job as a race engineer. In general camber change is not something to be minimized for it's own sake (the chassis performance envelope is a multi-dimensional topography - very little about it can be changed without affecting other perhaps more important factors) - the JDM guys don't do what they do simply to control front dynamic camber. </TD></TR></TABLE>

yea i know bro!!!
i just noticed too that i need to replace my right front endlink since its broken now...
now that we bring up de-cambering..
se eim going to be running 2 front 3 rear that is why i was considering doign the 12 rear or just sticking with the 10.....

soft damping settings on the street with turn the **** at the track....

 

how are the buddy clubs? i can't deciede if i want those or the bilstein pss9s

they are good bro i have ZERO compliants about them..

 

I'm running the JIC FLTA-2's with 12/10 setup.

I hear the BC's blow out fast. My friend has been through two rear coilovers in under a year. Their good for the money, but theirs better set ups out there.
