I've got poly motor mounts right now, honestly I can't stand the vibration, I've been putting my car in neutral at stoplights because it gets so bad. It's winter right now, so I'm not gunna be doing any off the line racing for awhile anyway, so I'm thinking of swapping the poly's out for the stockers at least for the winter. What are the pros/cons of keeping the polys in anyway? Someone told me to leave em in because it's better for the transmission? Thanks.
