Poly diff mounts?
Hey all
I was all set to install my poly diff mounts today and the guy who was helping me press them in thought it'd be a bad idea... he mentioned hitting curbs and such with poly diff mounts can break the diff housing? Has anyone heard of or experienced this? I'm not opposed to the mazdaspeed rubber ones, but I already have the energy poly bushings...
Thanks

I think the fear is more hopping curbs (think turn 3 at Road Atlanta) or riding really tough curbs (turn 10 road Atlanta) but I wanted to be sure I wasn't crazy for thinking they'd be fine.

Someone explain to me how hitting a curb is going to snap the carrier housing? That is not a moving part of the suspension.
I can see having crappy OEM engine mounts that allow the weight of the engine/trans to load the diff carrier when fitted with Poly/Delrin. Not a good situation indeed.
FWIW I ride curbs all the time with Delrin diff mounts. Never had an issue. Then again I run BFW drop mounts. Prior to that I was on AWR mounts.

I hit a kerb and broke the diff carrier once.
Physically hit the kerb.
As in, I dropped a wheel and physically struck the bottom of the diff, with a kerb, with the full weight of the car, plus any additional force from inertia.
Any kerb that can be hit hard enough with the tires to damage the diff carrier is going to **** up so many other things first that the diff carrier will be an afterthought in your repair plans.
