So far there has only been a few, and now you, that seem threatened by a reasonable discussion and resort to throwing stones.

I am not threatened by a reasonable discussion there Bucko...far from it. I am in the consumer's corner on this one.

I don't understand why, as FFR customers, you are not pressing these guys for a legitmate resolution to the issue????? There should be a collective voice forcing the issue instead of waiting for a disaster to occur.

You are asking members of this forum for data on the failures....WHY NOT ASK FFR?????? If they gave the specs to Bilstein to design a shock for their roadster, don't you think they would have the data? Maybe their specs were wrong.....ever think of that?

IMO, I think it has dragged on because too many on the FFR forum are praising the Smiths for their 'quick reaction'.

I think its far from acceptable the way its been handled.

And that just my opinion.....so neener...neener.

"Bucko...neener neener"

How cute. Just like a five year old.

Hey...I'm not the one with the shock problem...if you guys went after FFR the way you go after folks responding, maybe you'd have an answer from them by now. At least on this forum, the moderators let you discuss the problem.

Yes, I am a 5 year old that successfully built two Cobras on my own....and they did not have these problems.

Having read this from beginning to end I'm going to chime in.

There are posts from those that offer reasoning and contribute solid information to offering me a better understanding of the issue......

Then there are offerings such as the participant quoted above, who, upon reviewing this posters contributions and those of a couple of others, it has become clear that these participants.........

For the people that like a little vodka in their Koolaid, What do we think about my nuts? I'm not an engineer, but I can make or break anything.. I believe in them enough to send them out for free... In the hopes that St. Peter will overlook some of the other stuff...

Hoofa,

Attached is what was originally posted by me in regards to a Bilstein shock failure, clearly the pictures are no longer on my server that accompanied this post, but the facts and the third party (without a financial hook in this battle) analysis (from a shop that rebuilds Bilstein shocks for race teams all over the country) show what the real issues were. After reading this analysis, you might want to reconsider sending out the nuts.

"Ok, let's start off with the Bilstein shocks as submitted by Marty D. who wrote to me the following:

"the shocks were mounted with body up on the front suspension. Lower control arms are from Fortes. I had some spacers between the spring hat and the heim joint to prevent any interferance from occuring with the lower arm. When I looked at the shocks I couldn't see any signs of contact between the arm and shock. There are about 5k miles on the shocks. Many of those miles were on bumpy back roads driven at speed."

Ok with that out of the way, let's look at cause and effect with the following four photo's:

From the looks of things, there was not only some unusual lateral loads (wear on the outside of the lower spring seat and threading), but my shock guy (a custom rebuilder and master WD for Bilstein, QA1, Carrerra, and Pro Shock) sent me the following email:

"From the shock it looks like the center to center of the mount on that car are at 14.5 " center to center this will allow a 5" stroke on the shock and looking at the shock, also looked like there was only 2" of shock left when the car is at ride height so that means there is only 2" of shock available to extend so constant battering on that shaft at full extension is what caused that shaft to rip off. By no means was that a shock manufacturers fault but a poor choice of mounting a street car should have at least 7" of shaft length to deal with at ride height 3/1-2 " of shaft for bump and rebound the reason that some other shocks might get away with the constant beating full extension is that the QA1 shocks pro's and carrera shocks use a thicker shaft that is much softer than the bilstein but this still does not make it right".

Just thought you would like to know his thoughts on first glance, he is going to take them completely apart in the next day or so to check the valving to see if anything failed there as well. If he finds anything else of interest, I'll let you know."

Original post on ffcobra:

Again both posted the same day back in 2006 .

Here we are in 2008 with the same issues, so the question remains, what is the difference between then, and now?

That is the only concern with my nuts. That they steal a little travel. The next batch I'm making are going to be significantly shorter. After I broke them I figured out that I don't need the sleeve to be nearly as long. Basically it comes down to the lesser of two evils. If the shaft is going to be taking a beating anyway, I'd rather the beating is on an area that has 40% more material and isn't scored. My new nut without the magic washer should only steal about 3/16" of travel. Can you ask your Shock guy about the nuts? I can't afford new shocks, I blew my wad on my nuts....

Just so I understand correctly, by beefing up the stress/break point on the rod by encasing it in a longer heavy walled nut is that intended to strengthen the break/stress point?

If indeed this is the intention would not that stress be passed on to the next weakest point in the "link" and cause potential fracturing or over-stress that point as well?
