RSS 996 Engine mounts, too much vibration?
I have a 1999 996 C2 cab as a daily driver and often take 2 hour plus day trips. Needing new mounts, thinking OEM, but tempted to put the $$ on an RSS upgrade if it's not too much NVH feedback in the seats or rattles. Convertibles already have a stiff structure, so I'm not sure what the result would be.
Anyone have them or have any insight? Thanks!

Sorry Boss. You must have misunderstood. Watch the video from a few posts above and it will outline why you do NOT want to use solid or semi solid mount on your 996. Just like you, I was all set to get a set of the RSS mounts. Then it became clear to not do it. Instead, use either new factory mounts or REIN mounts which are in essence the same as oem since REIN makes them for porsche but are cheaper.

My service tech said that which was roundly disputed when I spoke to RSS directly. They said the N H would be less in a Cab.

I have an '02 cab. I changed to RSS mounts shortly after buying the car due to worn out mounts and low hanging engine. They did add some NVH but only at certain RPM's. There was something in the door that would rattle. I was too lazy to figure out what it was. Also had a small vibration on the center console. Needed to touch it to know it was there. With the new engine, being assembled at the time the video was done, the RSS mounts were replaced with the Rein's. No comments on noticing any difference in power as the engine is a completely different beast now.

Thanks for the concern, and to your point, I’ve watched many videos and read quite a few 180 degree conflicting opinions, even those about dyno results. In the end, I used points to buy the RSS and figured that the worst that could happen was reselling them and going tamer or OEM. A long chat with RSS locally was the last step. The 3 to 4K range is the fun zone to me so I really cant know till I try it. I have a lift so it’s not that bad to do. The one RSS road test video from the UK swayed me and he reached out. Such a subjective move and I hope the dyno video will not prove true in my case. (I have to admit that I am seduced by their beauty!!) I will do these as my one last daddy/daughter wrench job before her wedding and report back. Thanks for caring!
Ok...fine...enjoy

My car is not that car. As many posters pointed out who question that video, there are also variables that influence those results. You may be right, the video may be right. There are also true believers out there otherwise they would be recalled. It’s like how much HP intake changes really get you or exhaust mods. It’s also road feel. I spoke to RSS not so much to get a “pitch” but since they have sold so many what to expect in a cab. My tech recommended OEM, the mechanic on the floor said RSS. To me, there are things in life that are best tried and this is reversible if I don’t love it. I get your point and respect that.
