Happy with RS Engine Mounts?

I have slowly been refreshing the chassis of my 97 C2S (60K miles) during the last 18 months of my ownership. I’ve done the following and have appreciated the incremental improvements towards getting that new car feel. So far I’ve done:
- Porsche Classic Greens + M033 springs
- Walrod bushings with new LCAs
- Rear toe bushings, drop links
- Tons of other non-chassis stuff (ceramic, PPF, Fister 2s, belts, Classic Radio, new OEM speakers, brake pads).
I’m really aiming for OEM +.
The next thing I’m strongly considering is RS engine mounts. Despite the car feeling so much more taut than when I first got it, I still feel some mushiness in the turns and during weight transfer. I don’t believe the engine mounts have ever been changed and so I’m considering RS mounts as the next incremental step. Am I on the right path, and what has your experience been with this upgrade?
thanks!

This is a definite YES in my book. I've yet to come across one person that went to RS engine mounts and wasn't grinning ear to ear, leading them to say "gee, I really want to go back to sloppy hydraulic mounts". ![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
Stiffer trans mount is where I'd draw the line, as that's something that folks generally do report some NVH changes but not so with RS engine mounts.

Did you install it in the right orientation? Amazingly it must go in in the right rotation or yes, you will have a ton of NVH. Blew me away such a small change could make such a difference.
check the FSM, there a picture that shows correct orientation

Going to take the opposite point of view. I tried RS and one other type (wevo) before back to stock. For reference mine is a C2S with a supercharger which adds a lot of cabin noise, pss9 which add harshness to the ride, rs sway bars. I removed the cat and have fabspeed crosspipe with either none or sport cat which also ups the noise. So am not opposed to and like some additional noise. But the motor mount created an increase in vibration that just made a buzziness in the cabin. Things that never vibrated did a lot over 4k rpm.
Like suspension its all subjective and guys who love them say its not noticeable. But it is very noticeable IMO even above my other noise sources.
I would try to get a ride in someones car that has them.

Where can I find the best price? Can anyone verify part numbers?

If your gonna do the RS Motor Mounts …. Make sure you do the Golden Rod, HD Transmission Mount, and Short Shifter!
