Without question the best mod I have done was swap out the crappy old rear engine mount for the 95duro medieval mount. I remember the day. It was a complete transformation (fantastic ). It felt like I had an extra 30hp atw. The vibes were a bit harsh at first but they settled down and I hardly even notice them now.....except for when the AC is on . It's like the compressor creates a resonant frequency which reverberates throught the whole car and most annoyingly throught the clutch pedal. If I lived in Melbourne still i wouldn't care so much but in Cairns you have the AC on for 70% of the year. Anyone else had similar issues with aftermarket mounts and the AC? Any tips for reducing the vibes from the compressor?
