Well I have now got my TRZ Mount from Tim (DISIMS3) and will fit it in the next week or so.
I am also waiting on the CP-E mount from the group buy, so hopefully over the next month or so, I will be able to do a direct comparison on the pair.
I normally do over 900klm a week so they should bed in fairly quickly, and I should get an idea fairly quickly.
My CP-e engine mount has bedded in fairly well now and the vibrations are significantly reduced, they're at their worst around 730 rpm (on Dashhawk) below and above this it's smoother, I've just discovered the seismograph app for my ipod touch so will record some vibrations over the coming days!
