The Function-X are pretty comparable to a stock ride. Maybe just a wee bit on the stiffer side. Spring and/or dampening could be adjusted to counter this if need be.

 

How difficult are these badboys to adjust? I never owned a set of adjustable coilovers...

 

not difficult at all. Its like anything else, once you set your initial ride height, and get aligned thats that.

So what the other differences besides 6k 5k and 8k 7k spring rates between the function x and function xs?

 

Function X are 30 way adjustable for dampening, the Xs are 6 way adjustable

The X version is a bit more track oriented - basically on the limits of what you would want in a streetable setup. The Xs by comparison is much more street friendly, but the perfect setup for the guy that wants to drive the car during the week, take it auto-x'ing on weekends and maybe do a few track days a year. It's a truly amazing setup, and the versatility on them is something rarely achieved in a coilover

 

Sorry, to clarify my previous question, how does one go about adjusting the dampening? Does the car have to be raised or can pull over and adjust them at any point? Sorry for the newbie question but the only set I ever played with were the FLEXs with an edfc, I was impressed though.

 

the adjustment on both is at the bottom - it is easier to do with the car on ramps or jackstands, but not necessary - can be done with the car on the ground.

 

Does anyone actually have some shock dyno results they're willing to share on these shocks?

And as far as adjustment are they typical Japanese shocks where the rebound and dampening are adjusted together? On the Hondas, their dampening adjustment seems to be much like standard box issue JIC's, with their dampening being all over the place.

 

They are typical coilovers at this price point where rebound and compression are adjusted together, yes. You dont' get independant compression/rebound adjustment without a large pricetag typically, and what I have personally found, 9 times out of 10, is the coilover is much more capable than the driver

As for shock dyno #'s, I'll see what I can dig up for you - not sure if we have any though, but I will check.

 

I'm confused.. are the X's 30-way and the V6's 6-way?

If so, could the X's be tuned for a more comfortable, yet better performing setup over the stock KYB's?

 

There are several Zeal Coilovers for the Evo:

Function X
Function Xs
Function V6
Super Function R

These are the most prevelant. The V6 are also 6 way adjustable, uses spring rates of 6 kg/mm front, 5kg/mm rear. The X is 30 way adjustable, the Xs is 6 way

Adam,

What's the difference between the V6's on your site? There's two regular ones and two Swift ones. Which one is better for daily driver/auto-x? Or would you recommend the Function XS since they're newer? I was thinking about going with the Swift Hard setup.

P.S. I think there's a typo on the site too. There's two Swift Soft setups.

 

There are 2 basic kind of Function V6's for the Evo - soft type (more street oriented), and hard type (more track oriented). Within each one, you can choose between the Basic spring and the Swift type spring.

Here is some info on the springs themselves:

Q: Are your springs linear or progressive?

Linear.

Q: What is the difference between the BASIC and SWIFT spring?

With the exception of the Function X-Series Coilovers, ZEAL uses BASIC & SWIFT, original springs manufactured by the same company, a very reputable spring manufacturer in Japan. The main difference lies within the material blend.
The SWIFT spring uses a "softer" material and although the lengths between the SWIFT and BASIC spring may be equal between applications, when "stretched out", the SWIFT is shorter with more coil gap and less coil bind.
On the flipside, the BASIC spring has less coil gap and a somewhat longer life span due to its more "harder" blend of material.

Q: What is the X-Coil Hyper Spring?

The X-Coil Hyper Spring is our new linear spring used in conjunction with the ZEAL Function-X and Xs coilover systems. This thicker, yellow spring uses material that allows for no distortion at extreme expansion or contraction. Motion and response is exceptionally stable within all ranges with no friction loss and no coil bind achieved through advanced manufacturing capabilities. Driving feel is extremely smooth with no residual bounce, especially during high speeds. This spring enables a certain “sticking to the road.” The Hyper Spring X-Coil is available in both ID60 and ID65.

Q: Do you recommend the BASIC, SWIFT, or X-Coil spring for my coilover?

We recommend BASIC for street-type and SWIFT for circuit-type driving.
The BASIC spring, with more coils, will be more "giving" in harsher, road conditions.
The SWIFT is more responsive and superior in handling compared to the BASIC spring, thus is recommended for smooth-surface, track/circuit conditions. The SWIFT spring will have less of a cushion-type of feeling for harsher, bumpier, street-type conditions (especially in the US where road conditions are generally harsher as compared to Japan). However, we will begin to greatly focus on the X-Coil as results show that this spring is by far the most superior in terms of performance and life.

Q: What is ID60, ID65?

ID stands for "Inner Diameter" of the spring, thus ID60 equals an inner diameter of 60mm. With the current exception of the 2003+ Civic EP3 (rear springs), 2000+ Celica ZZT231 (rear springs), and 2002+ RSX DC5 (rear springs) which use an ID65, all of our applications use an ID60 spring.

Q: How do I know which replacement spring(s) to purchase online?

Function-Xs and Function-X use X-Coil Hyper Springs. All other Function coilovers use SWIFT springs, but X-Coil Hyper Springs can be purchased as replacement springs. In fact, ZEAL will begin to slowly phase out of the SWIFT spring as testing has concluded that the X-Coil is superior in many different areas. Function-B6 and Function-V6 use either BASIC or SWIFT springs. Let us know your vehicle and coilover type to figure out the spring rate, spring length and ID. Or, we can simply give you the part # if you already know the exact spring you're looking to purchase.

Basically, you can consider (for all practical purposes) the X Type and the Swift type to be relatively comparable, with the X type being "superior" in terms of it's longevity, and its ability to remain true to it's actual rate.

For a car that will see it's primary duty on the street with some occassional auto-x and maybe a few track events, the Function Xs is the best all around unit - the dampening adjustment range is truly fantastic, and since it is 6 way adjustable, each adjustment point actually performs a function. The only other coils I have used to date that were comparable in this regard were the Cusco Zero2's and 2R's (2R's being inverteed, whcih sounds great on paper and are better for strictly competition use but I have never found a practical difference in terms of handling, even on a strict road race prepped car). The Zeals overall are a better option, if only because they can be rebuilt here in the US, and a near infinite level of custom services is available should the customer so desire, where as with the Cusco you are much more "limited" in terms of your options

I just bought some used Function XS springs with 6 and 5 spring rates. Any suggestions for ride height and damper settings?

 

suggesting stuff like that via email is like giving you AFC settings to run - best bet is to find a competant shop to cornerweight the car and get it set up, or just start playing around and seeing what you like
