If that one bracket is the problem, you could probably use different bolts and thick washers in it's place. It doesn't look like that bracket serves any function other than to keep the three bolts together unless I'm missing something.

AFAIK, there are 2 versions of the plates. One that is the same height as OEM and one which is similar to the Dinan Stage 1 front top mounts that increase the suspension travel. So it has a shorter overall height (not ride height) than the regular GC camber plate.
Which one do you have?

Hmmm, I guess I probably have the one that's the same as OEM. They didn't mention 2 versions when I called and ordered. I'd definitely like to see pics of the other version now.

I could see that happening if the installer wasn't paying attention. The plate says 18ft/lb on it which is relatively light.

The plate I have (had) supposedly maintains the OEM stack and ride height. If you look at the pic by Bigjae above, the 2 bolts that you can see have bolt heads. The one you can't see has the head shaved off (since it is the one that slides under the lower plate--the other 2 only need to move around the side of the plate). What is left is a headless bolt seated in a very thin plate with a wimpy tack weld (not Tig?) to hold it in place. I've got plenty of pix to show soon, I'm still talking to GC though right now... This has been such an incredible time hassle not to mention disappointment and $$$, and I'm so over it.

GC should have a good idea of the reasons for isolated failures by Monday, we are trying to force the parts to break in every manner that we can think of.
Within a half hour of hearing about this, we started breaking bolts while remeasuring the force needed. We had already done this in prototyping, but when a customer has a problem, we have a "failure analysis policy" to revisit everything, starting with retesting from the beginning. You will notice that on many of the failures, the bracket had been tightened until it bent, and THEN the stud broke. However, there are also inconsistencies in the failures that could be the technique, material, or even in measurement. For recreational reading in the principles of measurement: Heisenberg argues that every measurement destroys part of our knowledge of the system that was obtained by previous measurements. If you have questions about these failures, and what is being done, please call or email Jay at GC. Just a quick pic of testing to failure. cpe9x test2 by Ground Control Systems, on Flickr Last edited by JM3; 03-02-2012 at 07:01 PM.. |

So was this an installer error?

I know this may sound like an obvious question but what are the symptoms or how did you know the bolt broke?
I guess the reason I ask is because ever since installing the GC hybrid plates I've had increased NHV's, which I understand and can accept. What I'm a bit disappointed in is that in addition to the additional noise I also get a really abrupt and loud jar when the suspension unloads abruptly. I'm not talking about getting air under the wheel abrupt but just on a rolling bump where the suspension unloads. This happens for me at both normal freeway speeds and at speeds as low as 15mph. Is it easy to tell with everything assembled if a bolt is broken or do you have to disassemble everything in order to diagnose? Thanks, Royce M |

Last I checked in that same way I didn't notice any loose bolts on any of the three bolts. What had me wondering was in the pics posted above it shows one of the plates broken and not the bolt coming free from the weld.
In reading more through the thread I think someone mentioned that of the three bolts one of the heads are ground down. I'm wondering if the GC Hybrid plates are different. I'm looking at some pics of mine and one done by another poster and none of the heads are ground down? Am I missing something? Do the street plates use a different under mount plate? http://www.m3post.com/forums/showthr...control+camber Also one other question I'm curious about is where on the camber plates does it say the torque spec is 18ft/lb? Is it engraved somewhere? Thanks, Royce M |

That's where it's engraved on both models I've used. On top of the thick grey plate near the degree markings.

Yes, the plates shown in that old thread are a different type/design. Those bolts all have heads. GC (JM3?) could prob explain it better than I can.
