Installing RS Engine Mounts....

After much deliberation and research I decided to bite the bullet and replace the rear engine mounts on the Cayman S. The resins being they were original to the (2006) car and it was on my list of refreshing some of the 'consumables'.

For those who have had this done before and gone down the standard replacement route you will be aware that the original (to the car) Porsche item comes as an engine mount AND mounting bracket at just shy of £190 + vAT each (less a bit of club discount).Some of the US forums have indicated that the 993/964 RS mounts will fit if you split the original Cayman mount from the mounting bracket. This is relatively easy, it just needs the relevant Torx socket to remove the centre nut.

The bits needed are:-

2 x 964 375 043 81 RS engine mounts
4 x 901 305 311 00 Seats
4 x 999 025 074 02 washers

And 2 x 110mm stainless steel bolts along with 2 x stainless nylon flange nuts.

Here are the parts ready to fit (minus the nuts) :-



I put the car onto wooden blocks under the rear end (my preferred method) and gently supported the gearbox with a trolley jack.

The original mounts were fairly easy to remove once the bolts were undone. Here is the original mount setup:-



Once the Torx nut was off and the original mount was removed from the mounting bracket it was a very simple job to reassemble the RS mounts (loosely) onto the existing mount. Here is a pic. of this prior to fitting to the car.:-



Finally, a picture of the left hand side mount installed in the car:-



Interestingly, the left hand one was the first one I did and it appeared that there was quite a bit of 'sag' from the old mount given where the gearbox was sitting. Once the left hand one was installed, the right hand one was much easier and no real evidence of 'sag'. Unfortunately, I ran out of time for a drive and I have the front mount still to do, but will report back.

Happy to share my experiences on the forum or via PM if folks are interested.




Rgds.
Chris
