I'm a little torn on which one to get. TRZ says they're the best but of course everyone is going to say that about their company. My friend has the TRZ mount with the race bushing in his car and it's 6 months old now and it vibrates something horrible. i really don't want serious vibration i've had enough of that from my honda days with my engine swaps i had with solid mounts. BUT the street unit is a two piece which they say helps reduce vibration and is better then a one piece mount. I'm going to get the race bushing 90a i believe no matter which one i get cause it's pointless to get the softer one but since i'm getting the stiffer bushing is it going to matter which one i get. I know alot of poeple on here are running the trz but anyone running the street unit ?
