yea, before I put the poly mount in, I had a bad vibration at idle (common in 4th gen, right guys?) and my steering wheel would be vibrating, and once I put in the new poly mount, it actually got worse... when I come to a red light, my steering wheel vibrates like crazy, its annoying for me....Especially since I live in NYC, and am constantly in tons of stop/go traffic, but I would definitly do it all over again, poly is cheaper than a new mount, and the shifts are nice and crisp. I guess I should also check my rear mount, I'm sure that one is probably busted too...
