Thread: effect of a worn prothane rear motor mount.

Bringing this back since no one posted up photos yet of what happens to the rear mount after time (this was 2 years worth in a roadrace car FWIW)

^^^What Symptoms show themselves with the center ovaled out like that? I have prothanes on my track car. I have to take a look at that rear mount.

Visual inspection is what told us....and isn't all that difficult to do.

I'm starting to get an engine rocking sensation at times on decel or abrupt lifting in high rpms. I've had mine in for about 4 years now. I figured the little GA wouldn't have enough power to stress the mounts. Now I need to check mine. I have new cross member to body bushings installed to eliminate that.

I make a larger sleeve for the B13 Prothane mounts here's a picture of what they look like.

I never knew this. I definitely need to get one or a few.
