Suggestion

I was also changing the L cam sensor and the #4 plug/coil that I couldn't get at the first time, so I lowered the engine a few inches and removed the rear engine crossmember (because it was in the way of getting the buggered bolt out of the cam sensor)

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Suggestion

You will need to take off the rear bumper, support the rear of the engine, and use a 15mm deep impact driver to get the crossmember - motor mount nut off, and (I think) a simple 13mm socket for the motor mount to body bolts.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Looking at replacing the engine mounts and wondering what everyone is using? Looking on Ebay and you can find them for like $85 for brand new OEM ones? Just wondering what folks are using.

POST 2Original post

I went Porsche OEM motor mounts. Didn't want to create bad engine harmonics throwing off the knock sensors.

POST 4Original post

Quotes source post: 19586465

This. Not $350 each like the Porsche branded but the same. Eeuro has them for $100each.

POST 5Original post

I went with the RS mount from Rennpart. Comes as a full kit and I opted for the URO first since I wasn�t entirely sure I was going to like them. https://rennpart.com/product/rs-engine-mount-upgrade/

POST 6Original post

Quotes source post: 19586523

Are you liking them? Mine has OEM Rein, and I want to improve it a little without getting wild and the RS ones seem to be the best middle ground

POST 7Original post

I've had the RS ones for 2 years + now with zero issues. Definitely tighter than stock ones but not as stiff as some other aftermarket ones I felt. They still use rubber which will have more natural give than even the softer polyurethane mounts.

POST 8Original post

Quotes source posts: 19586589, 19586584

Like Pete, I�m happy with mine. The car had semi solids of unknown origin that I didn�t like too much. Rennpart is a sponsor on here so I generally like to give them business.

POST 9 / ORIGINAL POSTEROriginal post

Since I'm not tracking the car or going nuts with it, is it safe to say you get what you pay for. Reason I'm asking is the ones on Ebay "look" exactly like the Renn ones on the Renn site but they are like $90 instead of $300.

POST 10Original post

Quotes source post: 19586625

The $300 Renn kit uses URO aftermarket mounts and all new hardware. I�m sure you can find the mounts alone for less but look for hardware while you�re at it.

POST 11 / ORIGINAL POSTEROriginal post

Has anyone done the poly urethane modification to their mounts. It stiffens them up more yet allows for some movement? I'll probably give that a shot as well.

POST 12Original post

RockAuto has the Uro RS mounts for about $85. I sourced the fasteners from Pelican.

POST 13Original post

Quotes source post: 19586523

I don't blame you for going with the URO after just seeing the genuine Porsche kit has doubled in price since I bought mine in early 2018. It's currently $800.00 for the Porsche kit from Rennpart vs $400.00 in 2018. It looks like I used some kind of coupon code so it brought the price down to $360.

POST 14Original post

I just replaced mine. I used the REIN from rockauto $100ea https://www.rockauto.com/en/moreinfo...t=5552&jsn=441 You will need to take off the rear bumper, support the rear of the engine, and use a 15mm deep impact driver to get the crossmember - motor mount nut off, and (I think) a simple 13mm socket for the motor mount to body bolts. You also have to remove the secondary air pump on the left side. Paul

I didn�t have to remove the bumper.

POST 17Original post

OE Porsche + didn�t have to remove the bumper I watched a half dozen YouTube videos on replacing the engine mounts and not a single one recommended removing the bumper

POST 18Original post

RSS mounts made a big improvement in the feel of the rear of the car. Much more planted and predictable. Yes, more vibration and noise, but everything is a trade off. You generally get what you pay for.

POST 19Original post

Quotes source post: 19586699

Never tried it. If you want a stiffer mount, go with the RS mounts as Pete and Joel have suggested. Why go thru a DIY exercise if you dont have to. But I have to say, the Rein mounts work great on both the track and street. I don't give them a second thought.

POST 21Original post

I had a BEEOTCH of a time getting one of the 15mm nuts off. I used PB Blaster, a long breaker bar, a propane torch, and a 110v electric impact driver with a 15mm deep impact socket (I had to drive across the bay bridge to get the last 2) All I remember was "I am glad the bumper is off so I can see what is going on up there..." I was also changing the L cam sensor and the #4 plug/coil that I couldn't get at the first time, so I lowered the engine a few inches and removed the rear engine crossmember (because it was in the way of getting the buggered bolt out of the cam sensor) I guess it can be done it without removing the bumper. Paul

POST 22Original post

I did OE mounts maybe 5 years ago and no complaints.

+1 to this, same thing for me.

POST 24Original post

624 RSS Performance Engine Mounts - RSS / Road Sport Supply I went with these. Great company to work with.

POST 25Original post

We hear that the harmonic vibration creates a problem, but nobody has come on RL to say they actually did have a problem. Would love to really know if it's true.
