This section is pretty dead but i thought i would give it a try.

can you revalve shocks/struts for example for 500 600 lbs springs but run 450 lbs springs?

 

Dead, perhaps, but usually fairly accurate for relevant questions.

Your question is straightforward, but your example is unclear.

Rebuildable shocks can be revalved to work with higher spring rates or to provide desired characteristics or adjustment range. Typically, shocks by Koni, Bilstein and a few other companies are rebuildable, as are most of the shocks that come with coilover kits.

 

the suspension i went with has 370 lbs in the front and 285 lbs in the rear. i plan on running 450 in the front and something higher in the rear but if i decide to run higher spring rates in the future wouldn't it make sense to have the re-valved for like 500 or 600 lbs springs?

 

It would make the most sense to have your shocks valved for the spring rate you're using +/- maybe 100 lbs/in or to go with adjustable shock damping that will suit your spring rates.

I'd suggest consulting a specialist and just setting things up right from the start rather than just incrementally making things stiffer for no apparent reason. There's a lot more to suspension than just "stiff" and "stiffer".

 

Yea most variables can be calculated. Remember vehicle weight I almost as important as actual spring rate. What are you trying to accomplish? Or just call the shop 813-333-1100 I rebuild/revalve most shocks. If you go double adjustable you can also set up the damper with a wider range of acceptable spring rates for your application.

 

I have a 06 zx4 st ford focus with Bilstein pss9 coilovers, the car is 2800 lbs with me in it. really can't find what the front to rear weight distribution on a 06 but they really didn't change.

this is a 04 model

LF: 865 RF: 797

LR: 468 RR: 482

Total: 2612

i would like to run the most thickest sway on the after market (stock is 21mm front & 20mm in the rear. The after market ones are 24mm front & 28.6mm rear) for a road race event with the highest spring rates.

I'm trying to set my car up for road racing but really don't know whats best. i lived here be for but never saw or heard of any road racing tracks. When i lived in in SC i was 2 hours away from road Atlanta (never got on the track).

 

As I think I mentioned, there's much more to handling than "stiff and stiffer".

If your goal is to have a FWD car that handles as well as possible at Sebring... both Jeff and I can tell you from experience that "too stiff" won't get you there. Sebring is bumpy. (as are many other tracks) In fact, some of the fastest turns that can have some of the most significant impact on lap times are VERY bumpy.

Don't just assume that you want the stiffest front and rear bars and the highest spring rates. If you want a car that truly handles well, that's not what you want.

 

the why do a lot of honda owners that run a 2000lbs cars with very light springs with the smallest sway/no sway in the front and 1000+ springs in the rear with the thickest rear sway?

 

I didn't say that SOME stiffness wasn't good. But, what YOU said was "thickest sways" front and rear and "highest spring rates".

That's wildly different than just "stiffest rear bar" and "spring rates that are appropriate for the track and to compliment the balance of the car".

To answer your question, a lot of FWD racers will run soft in the front and stiff in the rear because that's what a FWD car needs for balance and to be able to put down power when exiting a turn with minimum inside front wheelspin.

But, again, that's NOT full stiff all around. There's some thought and a lot of testing involved in getting such a setup right.

 

alright ok.


now i have also heard from some people that you can run really really high rated springs in the rear with a Hugh front sway.
