Suspension question/Spring Rates, etc.

Suspension question, again, but I must know:

Ok so I found this thread:
spring rates for various springs

Range is depending on model (Base, SS, SH) and taking into account they are progressive springs.

-I need clarification that the higher the spring rate, the stiffer the suspension is, correct?

-So a 2001 Type-SH spring rate is .2k Front & .15K Rear?

-What would be a stiff but safe spring rate be (I am willing to give up comfort for performance) 15k front & 14k rear? (IDK)

When I go up a drive way I think it would be cool if my prelude could do this, 1-2 wheels off the ground, like this integra:

Re: Suspension question/Spring Rates, etc.

Yes the higher the rate the stiffer the spring. Stock springs are progressive (rate varies on amount of compression), depending which after market springs you buy they could be linear (constant rate regardless of compressed height).

Re: Suspension question/Spring Rates, etc.

The 200f/150r relates to 200lb/in, not kg/mm. IDK where you are getting the K from, is that to save hammering out a couple of 0's. Given the roughly 62/38 weight distribution and the double wishbone front and rear setup of 5th gens you want to keep the spring rates in line with this ratio to maintain a more neutral setup. The thread you linked has lots of common spring rates.

Pic link is broken. I have 450f/280r springs in the 4th gen with a 22mm solid rear sway bar and I can't quite lift a rear wheel going over driveways. You would need a much higher spring rate, really solid bars and some pretty heavily dampened shocks to achieve this which needless to say would be extremely uncomfortable on the street.

Re: Suspension question/Spring Rates, etc.

This one crops up every few weeks, still haven't seen anyone actually buy the BC's though. 10k is a bit stiff for the front for the street and coupled with a 5k rear is going to make for some interesting cornering. You'd be much better off with Koni sports with Ground Control sleeves and Eibach springs, you can customise the spring rates at the time of ordering, just tell them what you want to use it for.

That Integra must be running a seriously big rear sway bar, the rear wheel looks like it has barely dropped at all (I'm assuming the photo was taken with the car stationary). You can put some fairly massive bars in a 5th gen (I think Neuspeed made a 28mm hollow bar at one point) but be warned that the sway mounts on Preludes aren't exactly solid. In order to clear the 4WS system on the 4G the rear bar is spaced down off the chassis rail by a few inches rather than mounting it directly to it or the crossmember (as in Civics and Teggies), makes for a lever action that can pop the mount out of the chassis rail (like it did to mine). They never fixed it for the US 5th gens even though none of them have 4WS. If you put a big sway bar in then put some serious consideration to beefing up the mounts.

Re: Suspension question/Spring Rates, etc.

If I was to stiffen up my lude with swaybars, coilovers, and strutbars, will I be damaging or wearing our parts at the same time?

Re: Suspension question/Spring Rates, etc.

Well message EBPludeSH and see what he thinks of them after 4 years. The concern is not with the initial ride quality but the longevity of the BC setup, although I hear they have gotten better in recent years. In the end the BC is a budget coilover, why bother when you can have a quality and proven setup for the same (near enough) price. You'll notice he has custom spring rates too, this would probably make the ride a bit more tolerable.

It depends how stiff you make it too. If you want to lift wheels then I suspect your spine will be the first thing to go. Your bushes will start to deteriorate faster and you'll start to notice a lot more creaks and groans as the chassis starts to loosen up, but if you're making it that stiff then you probably won't want to drive it very far anyway so it balances out. If you want a more street based setup then there shouldn't be that much extra wear and tear assuming everything is still in reasonable condition.

Re: Suspension question/Spring Rates, etc.

@tassievteclude, so you recommend koni/ground control-eibach combo?
What is you suspension setup? If you have currently have stock, then what would you replace stock with? Many people recommended KYB also.

Re: Suspension question/Spring Rates, etc.

I currently have USDM spec Tein Superstreets but I was about 5 mins from pulling the trigger on the Koni/GC combo before the Tein's came up, had them for like 5 years now with no problems and they hold up pretty well on the track. Given my time over again I'd certainly go the Koni/GC way though since the Tein's are a little under-dampened for my needs, I'm currently looking at throwing the 2kg heavier springs in the front and back (that Tein allow without re-valving) to try and reduce my epic body roll but I suspect it won't make that much of a difference.

You'll have to be careful when choosing what to go with though, many manufacturers for some reason exclude the SH from their parts list, GC do not but Koni do. AFAIK there is no difference in the SH suspension except for minor differences to do with the ATTS, but there are many SH owners running Koni's. Maybe someone with more experience with the SH *cough* Bykfixr *cough* can help.

Re: Suspension question/Spring Rates, etc.

Dang, I don't pop in on the 5th gen section too often. Did my homework (finally) though and ran through some of your other threads, I can see what the fuss is about now.

@ematthew, this is the third thread now regarding your suspension. FFS either buy something or start doing the research yourself. Some of us actually know what we're talking about (I don't mean me but I have been right once already this week), listen, learn, do things yourself, THEN start telling us how it's done.

I understand how yall feel but I wasn't getting the answers that I was looking for so I had to ask more than once, I'm still learning and I want to be 100% sure about something before I do it. Thanks for yalls input.

Then start asking more direct questions.

Also, read this before asking about suspension again http://www.korywilcox.net/files/sfaq2.pdf
I think it's stickied somewhere.
