yeah, my bushing is thunking like crazy too. I'm positive that this would sell like crazy. I'm sure that nearly every FC owner probably needs to replace their mount. Hopeful that this comes to fruition very soon.

My car is going into storage for the winter in 3 weeks. I will gladly purchase one but will only be able to test it's potential in May of next year. Will be watching this and waiting for updates on this part.

We haven't forgotten about the mounts, but they've been on the back burner for a while as we deal with a new machine and a second shop for it. Things are finally starting to settle back down and with all of the overtime we've been putting in, we should be able to start working on r&d projects again soon.

i think the tabs off the actual subframe are going to snap off or become an issue where the mount is going to just slide up and down

We've had a few installed in cars for testing. Fitment is good and although there is an increase in vibration/noise the guys testing them don't mind. Right now we are waiting for more distance to be put on the cars. This is a part that is already highly prone to breaking and we're not willing to risk selling something that hasn't been tested well enough.

If it works I will buy one asap. I'm pulling my diff tomorrow to find out if mine is busted. I will most likely need one based on my amount of clunking. I will order this one asap!!!

I've been analyzing one of the test mounts and it's still holding fine, but they bushings have more wear then I wanted to see. I'm trying to increase the size of the bushings to help decrease wear. I'm hoping to be ready to tool up for these soon. We've had a few new projects pop up and as a result we are a bit short on time right now.

it seems to me that the stock mounts are so prone to failure because of the shearing force being applied to the bushing, one side of the bushing being forced one way, and the other side forced the other way. with the way your bushings are laid out (one end facing the diff side, one end facing the subframe side) i think that the same shearing force will be there.

your mount looks way beefier than the stock and will probably last a whole hell of a lot longer with sustained abuse, but what if you changed the orientation of the bushing to make it a compressing force instead of a shearing force?

please excuse the horribly tragic ms paint skills.. i am no artist as you can see..

if the bushings are like this, then when the diff wants to go one way and the subframe another way, the bushings will just compress in the tube they're stuffed into instead of trying to rip in half. now i am no engineer by any means, so if there is something completely wrong with my thinking here then by all means slap me upside my head.

i was just looking at my stock diff mount the other day as i was reinstalling it and thought this might be a way to eliminate the shear problem that might be the cause of the short lifespan of the mounts

Sorry for the delay in getting back to you guys. This time of year is always really busy due to everyone trying the get their projects done and cars back on the road.

Blame you are on the right track, but there just isn't enough room to do it like that. At least not to my standards. The other problem is all bolts need to be properly isolated from metal on metal contact to prevent noise.

Pretty sure I just broke my mazdaspeed mount and that was WITH a pinion snubber, this product is sorely needed.
