You're welcome. As a referrence, my washers distorted like this after about 5k miles, half of those at the track. I didn't feel right about leaving the thick washers out in the first place and now I know why...

 

How does this motor mount differ from the RSS motor mounts, being I do not care for much more vibration or noise above and beyond my 3" exhaust and LWFW?

Is there a cost difference as well between the RSS and this motor mount?

Thanks

i would think the NVH characteristics of any motor mounts other than stock would match the lwfw chatter nicely i just recently installed the semi solids and the improvement is very noticeable, but NOT without increased noise/vibration. it is transmitted right into the back of your spine, and increases proportionately to engine rpm. i dig it.

 

i found it interesting in that i replaced the oem mounts with a set of torque solutions semi solids from usp motorsports. i was expecting a vibration increase like everybody talks about and what i found was NO difference from oem unless i lay my hand on the shifter. thats were i feel it. but aside from that its a great mod with no downsides i can see. i actually needed them to gain some needed clearance for my larger i/c tubing and boost hoses.

 

perhaps i should've gone w the torque solutions. i only like the increases in NVH because i know my car's performance is improved. N&V for the sake of N&V isn't necessarily my thing. interesting you don't feel/hear it! mine is very noticeable. but this is my canyon car. if it were a dd. no could do.

 

Great DIY.

Thank you for the follow up pwdrhound.

 

I am not familiar with the RSS mount. The Porsche RS engine mounts will very slightly increase the vibration felt in the cabin at idle. At anything above idle, the mounts will add ZERO, ZILCH, NADA, more vibration or noise compared to stock. I love them. The will give you a feeling of a much more solid feeling car, hard to explain...

 

Sounds exactly like the RSS mounts. I only noticed a slight increase in vibration and noise at idle (and even then it's hardly intrusive). Anything above idle there is no difference in NVH with the RSS mounts. I love them, great upgrade.

 

attachment should be the porsche technical info about rs motormount

 

Nice pics pwdrhound!

 

So with all the parts needed for the 964 RS mounts how much is it?

I know the RSS mounts are $350 and are top notch quality.

 

There ya go:

Just want to confirm this DIY is relevant to my 997.1TT

I noticed op has a 996

 

Great posts deserve a bump.

Helped me quite a bit.
Thanks Scott!

 

just got done doing this, very easy! good write-up. Wanted to add that the small silver washers are on a 3-4 week backorder from Porsche, very frustrating. I ordered everything except those, and picked up some grade 8 washers from Ace that are very nearly identical, by going off the pics in this thread.

The car shifts better, and definitely is more solid feeling when you take corners. No additional engine noise at idle or any other time, and I have a 964 RS flywheel and upgraded clutch.
