hmm.. you have polyurethane mounts. would getting them be the same or better than filling others with liquid polyurethane? and who makes them?Originally posted by Blue Bomber
They reduce engine/tranny movement, greatly reducing wheel hop on launch, and improving shifter feel. They're definitely worth the price, though they do give a noticeable vibration at idle, and sometimes while driving. You can also fill your mounts with liquid polyurethane (Shore 80A is good for this), and the car won't vibrate as much, or at all. Silicone caulk will work too, but the improvements will be much less, though there will be no vibration at all.
