Eibach are lower!?

I'm sectioning a set of KYB's, but when you section a strut you are pretty much cutting it open & throwing the guts in the garbage. if you see the guts of the kyb's you'll see why it's not much of a loss really though, while they do a decent job as a factory replacement, they are only about as good as a factory replacement too, meaning cheap $20 shock style dampers...

the guts of a factory or kyb replacement strut are about $8 worth of parts in an oil bath, that's it... the seal is the only thing that does much & after 25-30k miles it's pretty much done. I'm replacing the guts with a koni 8611-1259 dual adjustable race insert. perfect for the fx really... don't even need a new set of kyb's for this though really, can be done about the same with the original strut housing even as long as it's not all rusted up... to section a strut your just using the housing... I'm taking about 2" off the strut housing & may or may not convert it to a full coilover too which is easy too btw, just remove the factory spring perch & add a 51mm ID threaded sleeve, maybe use a 10" long 2.5" coilover spring, determining the rate is the tricky part though, may start at~300 & then try a few up or down from there.... take some R&D to hit the right recipe there but if your not looking to really go all out then yeah, that thread that merchant refered you to is enough for most really...
 
DAMN TC!:congrats: that was beyond well put. Honestly their should be no more posts after that. So yeah whats cads said, and save your money for a full system setup. Select few know what i mean. mums the word..
 
you talking about the coilovers that gtspec might develop? that may be an option, I'm out of the loop on that as he has a friend who has an fx & they will be doing the developing & stuff there between them now...

I'm thinking more along the lines of building my own coilover suspension eventually & in doing so, being able to use "the good stuff", instead of some generic fixed valving shock to use a good set of koni dual adjustables, & instead of using just a fixed spring from some supplier setting it up to be able to use standard 2 1/2" coilover springs so the whole range of coils from companies like eibach, H&R & stuff can be used with it. only problem is, just 4 koni inserts alone will cost as much as there whole complete coilover kit, & if real deal coilovers are used in the rear it'll take some chassis fabrication & stuff & cost even more. in the end a custom setup like this will cost at least double+ what gtspec is projecting there whole kit to cost, don't know how many would take there suspension that serious though, hopefully gtspec comes up with something decent in the price range there projecting, not overly enthusiastic about the apollos as a base to build on though... guess we'll see there...

*I thought you were done with the suspension :wink:

I said I was done for now... that was then thought :laugh:

no, but really I'm very happy with my suspension right now as-is. I won't be actually changing it anytime real soon, just playing around with the possibilities & setting up for the next stage though...

Jumbo, do you have any technical reasoning why you think it's history?

I agree that defects are a part of any manufacturing process but it looks like QC on Eibach's part is/was really low. Don't know if they improved it or not BUT my point is that you can't know as well...

Peace, Eg3. You are right - I don't have a technical reason. You and I have had this discussion before, I think...

I'm just going on my work experience which includes manufacturing and fabrication military specifications. I do (did) admit a bad batch could have made it out there. The only way to determine if the particular springs anybody has are "good" is to do Non-Destructive testing on them, which isn't practical cost wise for any of us. There are several different types of testing that would work (magnified x-ray, eddy current, etc.) and I have to assume (I'm pretty darn sure) that testing is part of Eibach's process. Thing is - I'm also pretty sure they batch test, meaning a small sample from a particular production run. So it's still possible for defects to pass. But that's true for all manufacturers who use this same method.

If we were an organized community and cared enough, we could report out the serial numbers on the snapped springs and I'd bet we'd find they all came from the same production run. No way to know without cooperation from Eibach.

From a materials standpoint, what Turbo said is mostly true. There are absolutely springs out there that not only settle, but are designed to settle or permanently deform a certain percentage. It has to do with the particular combination of metals used and the intended purpose. Where my logic falls short on this one is the fact that as far as I know, Eibach doesn't design their springs that way, at least not on any other product line. So it stands to reason the FX spring shouldn't settle - but I have heard that it does from several different people on the scene. Unfortunately I didn't measure my drop immediately after install, so I really don't know if mine is lower now. I just feel like it is. Maybe I'm just hoping.

Either way, I'm sure this discussion is most definitely helping everybody to form an opinion - which is sort of the point! The end result - I love the way these feel, handle and ride. Even if they snapped, I'd have them replaced by Eibach (1,000,000 mile warranty) and stick with them.
