mmk did mine over the weekend... i'm convinced the only ones required for honda are the 2 front torque mounts.

I ended up doing the torque mounts and the driver side one only. socket extension snapped attempting removal of the passenger one and i could not for the life of me figure out how to take the rear one off without removing the intake mani.

anyways to report in, used sikaflex 252 (i think its 72a) on just the 3 and the drive this morning is amazing... i'm confident the driver one isn't fully cured but the cabin noise is noticable at warm idle (800rpm) not so much the cold 1000-1200rpm idle.

I did this for not the performance side but to rid myself of 2nd to 3rd gear crunch at redline and it is now gooooone.


on a side note, i knew the driver side mount wouldn't cure in time due to the width so i ended up placing metal washers at the top and bottom gap. straight after filling they all went back on the car while 2 jacks supported the engine (gearbox and A/C compressor) so the mounts wouldn't be pressurise while uncured.

torque mounts dried including centre (but not fully cured) within 24hrs. the driver still feels a tad soft (un-dried) in the centre after 36hrs.
