ok so im trying to build a track 92 civic hatch and lookin for some coils that give me a good slam and are still worthy or being used on the track

some ideas i got right now are:
tein ss
buddy club racing spec
apexi s1
d2 rs


gimme some more suggestions please or pick from some of these
my budget is about 1500

Thanks

 

For that amount might as well get the most for your $$

Looks like they reside in your home state so you can probably PM Andy@AMR on this site and you can check him out! Custom built to your spec retail is $1450(you can get them cheaper than that!) for EF/DA/EG/DC/EK built in the USA, they also use Hyperco springs to your rate and Lifetime warranty NONE of the companies you have mentioned have that.

 

I had Cusco zero 2s in my eg, now I have them in my ek

Pretty happy with them, good for the street, not to harsh on the road

 

Why don't you just get the tried and true Koni/GC setup?

 

For $1500 the AMR setup might very well be better than Koni/GC... if you go custom-valved Konis you may end up spending more than $1500, and you won't have the separate ride height and preload adjustments.

Having said that, "slammed" and "track" do not go together, unless you plan on raising the car up and dialing in everything every time you go to the track. Then of course your alignment will be changing all the time.

 

did you look at the redshift STS tech page for a civic?

i'm using that as a baseline for building my autocross car...

Xau

 

but wouldnt the koni/gc be cheaper?

 

Progress for $1100 and they can be revalved.

 

Not for custom valving. If you need to run higher spring rates than 550 lbs than you need to re-valve.

 

Q aside: if one revalves KY for >550, can you still use them <550?

 

Shock gurus no idea?

 

Below a certain spring rate may well be over-damped, causing a tire to possibly "skip" across uneven surfaces. You'd have to discuss with Koni or whomever does the revalving the characteristics of the shocks and suitable spring rates with the final valving setup.

That's just my conclusion. I'm not really sure if Koni shock valving can be "increased" to suitably handle a larger range of spring rates, or if the valving is only "moved" so that the range of acceptable spring rates is moved up (both minimum and maximum is increased). So as I said, discuss it with Koni or whomever does the revalve work.

 

Thank you Patrick for your seemingly neverending effort in replying.

 

In sets like AMR and Pro-C, what exactly is meant by 'preload'?

Apparently there is a difference between 'preload' and 'shock length/ride height'.

So, does 'preload' mean giving the spring more presure than there would be with the just the weight of the car on it?

In such a case the damper would be fully extended (otherwise the spring/damper would be compressed by the weight of the car).

This would mean there would be less than normal rebound travel ànd that the shock would be 'topping out' all the time.

Both these things don't seem right to me, or am I missing something?

'Preload' adjustment possibility seems to me only usefull for finetuning ride-height.

 

Preload really only serves to keep the spring seated at full shock extension. It does not affect spring rate or ride characteristics unless you were to get close to the amount of weight normally on each corner of the car - 600-1000 lbs in most cases - i.e. never going to happen.

The full coilovers with separate ride height and preload adjustments allow you to adjust ride height without affecting shock travel. Just set the spring perches so that the springs are snug at full extension, then adjust ride height with the lower ring, which actually shortens or lengthens the shock body.
