InTgr8 has the "are they poly" covered. Cool.

If your application is track/street, the poly do have some level of advantage over rubber. Poly isn't as affected by heat for one. There is a difference between Red Poly vs. Neoprene Rubber and I've been able to test and prove that with 'Kitty's car and my car. Whether is as pronounced Black Poly vs. Neoprene Rubber is hard to say (no data). From the reports I've read or received, the black Poly do have more NVH than Rogue, but it's not as pronounced as the Reds.

Like I said in my second post in this thread, I think the ultimate answer to solving this isn't to go hard as hell on the transmission part but to address both ends of the issue at the engine and at the transmission.

Like anything with cars there's always some kind of trade off!

Whatever you do, please post your results!
