Ok so we don't know if the big change came from engine mounts or the inserts or a combo of all 3
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I just changed the original mounts on my 996.1 for the type911 RS mounts. I wasn't expecting much, but OMG what a difference! Car no longer vibrates at idle (passenger seat is now completely still). Cornering feels so solid, even though I didn't think it was bad before. Everything just feels 'tighter'.
It only took an hour too, so if you're thinking about it, just do it!
Cotsworld Porsche did the Powerflex inserts on my Boxster I think they were the yellow ones. It made the car vibrate and drone, almost undrivable at speed, I turned the car around and went straight back to Cotsworld Porsche to have them removed.

Thread 'Powerflex gearbox mount bush insert - 996 Review & Mod.'
6 Aug 2017
After I fit the Powerflex gearbox mount inserts I posted about the transformation it made to the car with regards to handling and NVH and stated that after I'd been on my lads holiday I'd review them and take appropriate action. I'm back off in less than 3 week on another 2.5k trip with my good lady and the dog so wanted to be happy with them before that so yesterday I decided to remove them and do the
infrasilver hack
.
With regards to the performance of these up to now (after 2 months and around 3k miles) they did bed in more as time/distance went on and the NVH was reduced, but...
