Default Function Form Coilovers... need help!

Hey everyone, i decided to sign up here cause I hear about it so much on 8thcivic.com and stuff so yeah.. this would be my first post lol

So, after all the hype about function form, I decided to go with it.

heres the quick review about em

fronts: cake. they were in and out, adjusting them were easy and there were no problems.

rears: heres the problem...

in this picture, you can see both F2 shock and spring in place. USUALLY, if you leave 3-4 threads left on it, you could get a nice 1 finger gap or a little more tucked. in this case, when we put the wheel on.. the gap was actually BIGGER than stock. stock = 2 1/2 fingers.. with the set up you see here = 3 1/2 fingers and almost 4. What's the deal? the spring is smaller than stock, the shock is smaller than stock.. i don't understand why it'd be BIGGER.


so what we decided to do was take that whole perch out, and let the spring sit on the rubber mounts (both top and bottom), sorta like how stock springs sit, we put the wheel on and it's slammed like no tomorrow.


so heres pics of the negative camber in the back, its ridiculous but i kinda like it.



there is no finger gap, you gotta stick your finger in and then bend it to touch the top of the tire.


so my question is... maybe those with F2 coils, or anyone with some insight... why is it that, even with the rear coilover at the LOWEST setting, gives a ride height which is higher than stock even though everything (spring and shock) is shorter than stock. How do I adjust it WITH the perch to make a lower setting? it doesn't make sense.

is it bad to ride with such negative camber and on such a low height? I know the shocks will be fine because the shocks are meant to handle heights like this.

any help would be appreciated!

yeah its actually not that bad.. but still, something I should be concerned about with tire wear and what not.

any ideas why it won't go any lower even with the coilover at the lowest setting? it's so confusing to me.

The Megan Coils had the same issue.
The rear spring on the coils went through 3 different designs before they got it right

Riding the way you are is

1. Ghetto
2. Dangerous

I'd personally remove them

The Function coils probably bought a set of megans and replicated them & never researched the design flaws.

and aren't those the same coils that another member posted SNAPPING in half?

i never heard of anything snapping in half, if it were on this forum.. then i definititely didn't hear about it

I'm gonna ask a shop to install em again and see how it works for them.
however, I believe your on 8thcivic.com.. and peenoysi has em, and is dropped quite nicely.. so i don't *think* its a design flaw.

again, another thing to think of is... since the F2 stuff is shorter than stock, why would the height be greater? this is the main thing that confuses me.

its a combo of the heigh of the rear spring & the weight they input on the design.

If its coded to withstand more weight then the rear of the car it will keep it "higher" trying to fight weight that isn't there.

did you take a ride around the block to let the springs seat a little before you took the perch off?

over time the springs will settle but intially you should take short trip around the block.

well i just went out because what type X said (being dangerous) scared me a bit.. I don't wanna drive and all of the sudden have the spring pop out because it pops out when the car is jacked up.

and I put the perches back on, took about 45 minutes.. and put the car back down on the ground again. one side is higher than the other, however both are set to the exact same height (both to the lowest setting).
It's a 1 finger gap on the right and a 2 finger gap on the left.

I did what dirtySOHC said, took it around the block, went on some bumps, took so mildly hard turns and came back... they seem to look the same. but perhaps it takes more time.

type x said that the springs don't settle.
but if they do, how much should i be expecting?

thanks for all your help guys!

just so everyone is aware, F2s were not the coilovers that snapped, they were the NEX coilovers.

goodluck with getting your issued fixed. i was looking at getting a set of these or some D2s, gonna wait a little longer.

thanks for clearing that up! gave me a scare haha

anyways, a word on these coilovers..

They're nicely built coilovers, you can tell that its not just a piece of crap they make and sell. everything fits like a glove.

the problems though are for the rear.. I'm not sure what it is. with the coils set at the lowest setting, meaning that its all the way to the top of the perch, there is a 1 figner gap. perhaps they made it so that is the lowest you go, but the fronts have a good 5 or 6 thread left and its already nicely tucked.

so like i said above, i put the perches back on and drove it around, one side is higher than the other by about 1 finger. Perhaps the springs still need to settle. I'll update in about a weeks time.

but so far, function form coils for the FG have had some kind of problem with not being low enough in the rear.

you can search ricebowl54 on 8thcivic, he has a thread about his F2 woes as well.

Hmm I was waiting to hear/ see things about the Function and Form type 2's on an Si. They seem to be sponsoring some of the hottest cars in Cali but other than the fact that I know they are known for going low I haven't heard much at all about them.

Like Type X said Megan had a similar problem with their rear springs, and maybe F/F is having the same problem but idk. Typically most coilovers for our cars have more room to go lower in the rear than the front.

And I definitely wouldn't ride around without the perches.
