need HELP with D2 coilovers

Post by **drifterBOB** » Fri May 21, 2004 5:31 pm

sorry to bother ya'll with this lame-*** question, but i'm new here and i just got me a new set of D2's. got them put on my 93 240sx coupe and everythings looking peachy, right? well, not exactly. the damper adjustment knobs on the fronts are stiff as hell and very hard to turn. hard as in you need a vise grip to get the knob to turn. the rears are fine. i can adjust them with my hands. using the vise grip you can turn the knob but the knob recoils back alittle. example: i'm on the 1st setting and i move the knob to the 2nd, let go of the vise grip and it goes back to the 1st. but if you keep at it, it eventually goes to where you want it to go. and i don't think that's working either, cause i've got the setting on the 5th mark and the fronts are still soft as if it was still one the 1st mark. has anyone encountered a problem like this or have any advice for me? please help me, for i am helpless and defenseless:pface

hmmm... i haven't had any probs adjusting mine, even after the piston bent when I decided to get a little too close to a tree at speed. Sounds dumb, but are you turning the right way?? :p

Post by **drifterBOB** » Fri May 21, 2004 5:31 pm

i'm turn the knob in ascending order according to the adjustment knob thingy (the knob with the 6 different settings). i was told to try turnind the other way, but it's hard to turn it the opposite way as well. i'm out of ideas. looks like i'm the only one with this problem (just my luck, stuff like this always happens to me):angry7:

sorry to hijack the thread, but where did u get hte coilovers from? i hear they're one of hte best deals on the market, and i want to pick up some, just am kinda skeptical, and htis thread isnt exactly helping me. Anyway, try spraying some WD4o on that mofo

Post by **Adikt** » Fri May 21, 2004 5:31 pm

hmm thats a dilly of a pickle u got there

anyone know why these coilovers are so damn bouncy ive had them in 4 about 400 miles already and they get really bouncey on turns. i think that there might be too much preload on the springs. any input?

Post by **j-z** » Fri May 21, 2004 5:31 pm

sounds like user error to me. i think you may be trying to force the thing to turn a way its not made to turn. every try turning the know the other way to see what happens?

Post by **Gonad** » Fri May 21, 2004 5:31 pm

Your damper knobs should just drop in the top hole and you should be able to turn it either way without too much problem.

When you reach the end, you will feel it pretty much lock up and not able to turn anymore.

Perhaps your shock is defective?

well this makes me kinda iffy on buyin em myself

nlzmo400r: No. drifterBob either has a defective unit or he just did something wrong.

Sorry but this isn't the first thing I've seen wrong with the D2's and 2k on a coilover is hardly enough to give an accurate reply on their quality.

I've put 30k on my Tein HA's over the past 1.5 years and I have had no problems, nor have I even had to adjust the dampening to compensate for damper wear.

Whats your spring rate and how bumpy is the road. How low is the car? Did you lower it with the spring perch or the lower adjustment?

Post by **j-z** » Fri May 21, 2004 5:31 pm

youre right mr obvious. i was just saying for the 2k miles ive had them on my car, theyre ****ing awesome. what else have you seen wrong with the d2s?

Post by **Adikt** » Fri May 21, 2004 5:31 pm

my spring rates are 7 kg front and 5 in the back. Its not that the road is bumpy and i lowered it with the lower adjustment but i preloaded the springs a bit so im thinkin that might be the problem

Post by **dreamsOfSkylines** » Fri May 21, 2004 5:31 pm

Probably the preloading thats causing the bounciness. My d2's adjust fine...

Incomplete machining and finishing of the productImproper dampening rates for the spring (ie. bouncing)Ride height adjustment issues (ie. binding)Missing components in the box

On top of the fact they can run anything from a 2 kgf/mm spring to a 10 kgf/mm spring on the same damper only goes to show me that they are sub-quality. However for the money I am sure they are decent, not everyone (including me) can afford something as quality as Zeal, or <enter name here>.

Which one did you see that was incompletely machined/finished? One person had issues getting his mounted on the top, but apparently that was because he had received a set for a different car, which isn't a quality issue.

D2 recommended a 9kg/mm front and 5kg/mm rear. I suppose a +-2kg/mm for the front and rear should still be within the dampening range. Also, I haven't dealt with coilovers before, but from what I understand, they have to be broken into before the bouncing/noises desist.

I'm not sure what binding is. Can you elaborate?

And one guy was missing a couple dampening adjustment knobs(even though you only need/use one).. big woop. That was just a careless mistake by whoever packaged them... doesn't really reflect the quality of the product itself. It's just a reminder that we aren't perfect.

The only real issue that I've heard of was the one posted in this thread. It's possible that this could be a quality issue, or perhaps just a user error? Good thing they're under warranty

A local 240 guy had problems with his adjustment in the rear of his car, amongst other problems.-chet"you get what you pay for"also, +/- 1kg/mm is quite a bit of variance in spring rate, IMO..+ or -2 means the damper wont be properly matched for them...even if its adjustable....

There was a thread I ran into that someone had gotten their's with a hole that wasn't fully machined and still had rough edges. I believe it was the adjustment hole for the tool. I can't find it to save my butt, not sure if it was on the UK forum or a US forum.

Breaking in a coilover does nothing to reduce bouncing. Bouncing is a result of the dampening being insufficient to the spring rate. Funny how they suggest 9 / 5 ... because thats a 80% stiffer front spring rate, which is not ideal for a 240. If it were, then you'd see more substantial companies incorporating similar spring rates. Much less racing vehicles.

Tein suggests no more than +/- 2kgf/mm on their coilovers because they have tuned dampening rates. A coilover that comes with 3.5 - 10+ kgf/mm spring rates without changing the valving is not tuned.

The mounting bracket was binding on the shock body. Evident by the removed finish on the shock body when they (D2) put it on.

That reflects on the quality control the company has. If something as obvious as that got by them imagine the non-visable passage rates.

Warranty is good, but do you really want to put up with dealing with it? If so, Kia and Hyundai are right up your alley

Have you mods gone to the K-Sport Group Buy thread and let everyone there know they are also buying crap products then? Seeing as these are the same coilovers I would think you would be offering these opinions there as well. I am no expert by any means, but it just seems like you are also in effect trashing a valued sponsor's (Trixracing) product as well in the comments you are making about the D2's (same manufacturing company, same design, just different seller and color).

I am not going to lie about a product for the sake of one of our sponsors making profit off of it.

And there have been plenty of instances where I have voiced my opinion on the matter, a quick search (red flashing button up-top) would reveal that. You as a consumer should be able to make your own mind up as to which suspension you'd like to go with based on facts. There are plenty of people that seem satisfied with D2 coilovers. I meerly mentioned that they may not be the best on the market, nor have the same quality standards, but I do not disagree that they are a good deal. From that point you are free to deduce your own course of action.

Post by **Torso** » Fri May 21, 2004 5:31 pm

Oh I understand Nismo, I did not intend to sound aggressive/defensive in my post, this forum has always been a great source for fair comparisons and opinions. I just was hearing such negatives about these when the majority of users seem happy as hell. I dang well know these are not the best on the market, but they do seem to be a good value for the money, of course only time will tell. Lets hope for the best

well in relation between the D2's and the next cost effective switch for suspension, basically only leaves the AGX/Eibach combo...and i would rather have the D2'S anyday of the week over that setup. In my opinion anyway.Although i definately respect Chet and Alan's opinions on the matter. I might swap mine for some HE's, but not sure as of now. That's only because my buddy wants them. We'll see though. I'm not sure i wanna pay for another alignment.

Post by **Exar-Kun** » Fri May 21, 2004 5:31 pm

TEIn basics.... but no pillow mounts

alignments are cheap compared to tires and bad handling...

hell if you lived in GA, we can align the car with you in it, to your specs for 39.99 (yes, all four wheels)-chet

unfortunately i don't live in GA. Otherwise trust me i'd take you up on it.=)

Post by **veilside180sx** » Fri May 21, 2004 5:31 pm

i've gotta find someone around that does alignments for that cheap. I know a couple of shops around PDX that some of them have 240's, but not sure if i trust any of them to touch my car.

Where in GA? I'll be installing my tein basics and D2 pillow mounts around the beginning of august.

You guys will be getting a visit from me soon for $40! You have a Hunter machine?

Could I also see the toe/camber change using the top sliding mounts on the front coilovers? Kinda want a street, then track alignment but just want to take the bit of toe-in I guess I'd get with the S13's rear steer setup.
