Strut Mount Bearing

[misterpeanut]

Hi All, I'm running MM Caster/Camber plates and their front track pack springs on Koni Yellows with an Eibach front anti-rollbar. Rather stiff setup. I was getting ready to install my bump steer kit and found the upper strut mount bearing blown up. Is this from a misalignment during initial install of the MM plates or are these things just weak junk and there are better options? I will say I have no clue if these are the original mounts or not as I'm not the original owner, but I'm willing to bet they are with all 110,000 miles on them. I suppose I should have used new ones when I installed all of the other suspension components. So maybe the age/mileage plays a part in this failure? Thoughts?

Just found Ford Performance has an "upgraded" unit M-18183-C

Anyone have any experience using this with an aftermarket Caster Camber Plate?

The GT500 (and 2005-2010 Mustang GT) strut bearings are different than the 2011-2014 Mustang GT. The MM plates (and if I recall correctly the struts) are also different between the two.

I actually have the GT500 parts* on my 2011 GT, primarily because it was convenient for me at the time. No complaints here, but I have less than 10k miles on them and cannot really speak to whether they are better than the 2011-2014 GT parts.

Unless they changed the rules, the SCCA does not allow bearings in the struts, they were all over this a few years ago at the runoffs, in the touring class. Which is weird because I'm unaware of any ( legal) aftermarket
cam/cas plates that do not use them.
Hopefully they've changed it, but you might check.

For SCCA autocross, they are legal in most categories other than Street...including CAM, which is where many/most of the Mustangs land.

Ok, so I just gotta stick with the stock setup and see how it goes. The guys at MM said if the bearing is blown up like in my pictures it was from a misaligned install. I'll let you all know how it goes! Thanks
