Ireland Engineering Rear Subframe Mounts

[Wallyinc]

Has anyone else had this happen to their Ireland engineering Rear Subframe Mounts? These have less than a couple of hundred miles and I have chunks falling off of them evetime I take the car out. I'm about to replace with oem, originally they had looked like this.

Urethane in that spot is usually not favored here....go OEM and get the urethane inserts that slide into the OEM ones.

Yep, bonding urethane to steel's not trivial.

 

The engine mounts are classic for this.  Urethane itself isn't all that great

in tension or shear,

especially if it's formed in less- than- ideal conditions.

 

See if they'll spiff you something that works in place of these.

Call it a test for the 'new and improved' Ireland...

It looks to me like your metal strap to the body is bent, which just might cause your problem.

Thanks for the advice @Einspritz. But I pulled the strap off this morning, its not bent. It's flexing here in the photo because the bushing is failing. It would go back to it's "normal" form when the car was lowered and sitting on the ground as well.

How's your differential mounts? They can sag too.

 

I've never been a fan of urethane anything as you just don't need it to have good performance.

 

Consider getting the mounts from a CS (Turbo), left and right, and be done with all the vibration. You'll still be able to keep up with the track cars....

Differential mounts are solid (oem)! I'll look into the cs mounts. thanks for the advice!
