So i booked a ramp today and had a few jobs on under the car. I fitted the uprated poly inserts to the original gearbox mount which replace the old thick rubber "washers" which sit either side of the oe mount.
I also drained the gearbox oil which hadn't been changed by the look of it for a while, and changed the leaking selector shaft seal which was actually very easy with the other bits out of the way while doing the inserts.
Some photobucket pics below but they don't show the entire job, however there is a write up pdf on the american website for the inserts.
In summary its not too bad if you have ramps. I wouldn't have been able to do it off a jack myself with axle stands. The inserts were 130 dollars or whatever and so far I've noticed its made the drive smoother for definite. Non of the harshness you sometimes get with hard throttle on/offs. I think I'd benefit from new engine mounts also but otherwise its worth doing if you are under there for other jobs. That bit alone took about 2 hrs start to finish. Car has done 73k.
Gearbox oil was 36 quid and the seal was 17 quid from porsche. Ramp time cost me 50 quid so overall its been a good saving over garage rates and i have job satisfaction lol.
I ran out of time to flush the clutch but I'll get that done at the service now with a fluid change of the brakes.
In the pics the black stuff on the mounts and brackets is waxoyl. You can see the oe rubber washers which were removed and the harder yellow inserts. If your original bush is torn or ripped it wouldn't help. You do have to drop the transmission on a jack stand by a few inches to get the bolt out but otherwise fairly straightforward
Hope this helps someone interested in the inserts.
