You only need a stable warm temperature for around 4 hours to avoid shrinkage as it cures from the inside out. After 24 hours the shore is stable. I will test my samples again but I am pretty sure they will remain unchanged. Would be great to get some feed back from anyone who does this mod as it transformed my 997.
It all started when I replaced both my rear arms on my 997 S as one inner bush had delaminated. The handling after replacing the arms with meyle was shocking especially under acceration mid corner and even in a straight line in 2nd and 3rd. Four wheel aligned 3 times and still the same. I then ordered a genuine arm and tested against two more brand new meyle arms and the middle bush was very different. The voids are there for comfort under load but on 2006 on 997 and cayman the bushes are solid but with a lower dura rating. This mod is very close to this later bush and deflection is about 1.7 mm less than the later bushing when subjected to 400kg side wards pressure. I tried 60 shore but it was 2-3 mm more deflection although this rating was great for my gearbox mount as the NVH is superb, I found the powerflex insert a little vibey. This makes great reading http://rennlist.com/forums/997-forum/440054-revisitng-the-annoying-2005-wiggle-bushing-issue.html My car is now completely cured of this trait.
