Anyone running on Cusco Zero II's?
 

Just wondering what you thought of them. They seem to be a decent kit at a reasonable price (compared to a JIC or HKS kit). Is the quality as good as an HKS unit? Have you tracked them?
Thanks in advance.

Oh- one more thing. Where did you purchase them from?

I don't have Cuscos, but they have a very good reputation as far as suspension goes, so I don't think you can go wrong here. HKS is known for their quality, but this is also reflected in their pricing.

they have funky spring rates, im curious

What do you mean, funky? What are they offhand?

10kg front 7kg rear...
from what i have read is that they need to be used with their sways to function properly.
the rear sway bar i think is 70% stiffer than stock...

thanks sugar britches

do some searches....several of us here have them

Sway bars are not ment to coverup gross error's in tuning/chassis setup. Sway bars are ment to fine tune a setup that is properly dialed in. The FM platorm has very low rear motion rates, which is the reason the oem rear spring rates are higher then the front.

Their are several good books on the subject of chassis setup, I would highly recommend they be read before going with a setup with the Cusco's specs. Frankly, do not listen to me, or to anyone that is biased. Do your own research.

Great write-up Gsedan35. This should help a lot. Thanks!

needs aragosta and kei office specs, i cant find the kei office specs anywhere.

I have the Cusco Zero-2R's with pillowball

but it's on my 240SX, so wouldn't make a good comparison.

Sorry for this dumb post.

Victor :)

I have the Zero-2 and the Cusco sway bars. Track time has been at Road America and Brainerd here in MN. I don't think I'd buy them again even at the $1200 I got them for. There just isn't enough adjustability.

Slow speed corners below 60mph I can use the throttle to help keep the car balanced easily. Above that, before aerodynamic forces contribute too much, it is pretty difficult to dial out understeer. The carousel at RA is a really good example of this. Speeds are 75-80mph, the radius is pretty constant until later in the corner. No matter what combo of tire pressures and dampening settings I use the car doesn't want to turn. It would be slightly better with wider tires on the front, but I still feel the the spring rates and the dampning aren't right. I'd like to get (should be getting) 5-10mph more in that corner on street tires...

I'll be upgrading to Tein or HKS for next year. Not sure which sway bars I'll go with yet...

From Gsedan35's writeup, the KW's look like a good prospect. I understand they are also made from stainless steel to prevent corrosion.
Anyone know of a decent North American supplier?

to add a few more...

tanabe type s-oc (ii) and ss (ii)

tanabe doesn't have thier specs listed for the s-oc (ii) or the ss (ii)on thier website yet; however you can pick custom spring rates on the type ss (ii).

silk road rm/a8 - 10k F 8k R

if somebody could find the rest of the specs on these 2 coilovers.

as a side note, i never realized that the tein type flex used such stiff springs.

ive actually considered the silk roads 240 guys love them

yea, me too ... the retail on them is $1700, so im sure you could probably find them for around 1300-1400, which isn't too bad. the spring rates are a little too soft for what im wanting, but i was told that they will make you a set with custom spring rates and valving ... but im not sure if this is true :confused:

my next set of coilovers will be the tanabe ss type ii as soon as they are released!

I called on the Tanabe's and your right Moroccan, they won't be avail. for awhile. They couldn' t say when either.

someone told me they are too expensive to put in production at the moment

poop. :mad:

ohwell ... i guess ill have to save a little more and buy the upmost quality brand ;)

aragosta's?:)
