My 2001 Z28 6MT is in need of a transmission mount. It sees regular autocross duty now with a mild STP/CAM-C setup. I do not drag race and I haven't been on a road course with it yet, but that may change.

It is driven daily, year-round in NJ.

Would an OEM replacement trans mount suffice, or should I install a poly mount?

I have a poly torque arm mount and the motor mounts are still OEM rubber in case that matters.

What do the experts suggest?

Thanks!

My experience... I blew up the small block and did an LS swap. Everything had to come out anyway! But I will say that LS mounts are easier to change then small block mounts.

If they aren't falling apart or allowing the motor to move around too much just leave them.

I put poly engine and trans mounts in when I had everything out of the car. It was a fight to get the motor mounts to line up but it didn't take too long. I would think it would be a massive pain in the ass in the car. The old mounts literally fell out of the clamshells when I removed them.

I also don't think there is much of an increase in NVH with poly mounts, especially with a loud exhaust. That's what I would personally do.
