View Full Version : Rear Motor Mount



Daytona 500

This is a brief write up for pouring 2 part urethane into the rear dog bone (motor mount). The kit is available from Energy Suspension Parts . com. This mount is almost 100% responsible for keeping the engine and transmission from moving front to back while accelerating/decelerating. With the lower mount out and only the transmission and front mount holding the engine in the motor can be rocked back and forth with very little effort. Also, if you drive aggressive and you keep your hand on the shifter you can feel the engine movement through the shifter cables.
This is time consuming and the dry time is 36 to 48 hours to fully cured. If you decide to do this it would be difficult to reverse. You may want to price a new lower mount before you start. That is the bad news.
The good news is this worked out very well, torque steer is reduced and resonating from the engine is minimal. You will feel some resonation ( is that a word ?) on start up, a bit at idle, and during take off. The later being the most noticeable to me. At high speeds I feel and hear no difference. If you have done mounts before you will know what to expect, and as with anything, it is a trade off. A bit of comfort, for a bit of performance.
A few things to consider; Power Flex makes inserts for the euro version. The rear mount looks very close, but the rubber insulator is a bit different. If they were to come out with inserts for the N/A cars tomorrow I would highly suggest that. The install is the same, no dry time and it would be completely reversible. I knew I would not want to reverse this so I went all in. Plus I got no patience to wait for the aftermarket to catch up.
So with out any more delay here is what you have;
I used ramps, set the brake and chock the tires. The long bolt will not clear the exhaust so you have to drop the splash pan and the front of the exhaust. 2 flange bolts and 1 bracket at the motor, and the first hanger. This gives you enough room to work. The mount is 2 bolts and it drops down. It does not hold the motor up, so no worries of it dropping. Once out clean with a de-greaser if necessary and then soapy water. As far as the urethane pour and prep follow the directions on the Energy suspension site.
I have some suggestions and a few pics below;
1. The manufacture advises not to mix small amounts, the kit is pre measured by weight. Not being one to listen I mixed a smaller amount by weight ( food scale ) and it worked out fine. I did this because I may choose to do the other mounts.
2. You will see where I taped the mount to seal it. This was no where near enough tape. the urethane will leak and it is messy to work with. USE the sand box. They suggest it for a reason. It will make your life easier.
3. They also recommend mixing for at least 2 minutes, I would double that. The mixture actually will thin out considerably before it starts to thicken up. If I do another mount I would increase the mix time and wait 5 minutes before I poured. ( depending on weather conditions )
4. Once you tape and set the mount in the sand, pour the urethane and watch it for several minutes because if it does leak you will have time to top it off with your left over mix.
5. DRY TIME, in 24 hours the urethane will set up BUT most likely not be fully cured. Use any spilled urethane to test if the product is fully cured. Fully cured urethane is very tough and resilient. It will not break apart. 36 to 48 hours to be safe.
6. I used small stainless measuring cups I got at wall mart, or use a small paint mixing cup IF you don't mix the whole kit.

7. I used 80 duro-meter urethane as recommended by the supplier.

If you wont miss the car for 2 days this really isn't that bad, absent an up graded mount or inserts. The more aggressive you drive and the more power you make, the more you will appreciate a stronger rear mount.

Instillation is straight forward. CHECK torque specs from a Fiat service manual and button everything up.


This is the Power flex inserts for the euro mount. Easier if they become available.

Yes, that is daylight you see through the mount, so if you opt out of this option, you may want to consider others as power increases from power related mods.

urethane poured and set up for 24 hours. Not fully cured yet.

This was my tape job to seal the mount. NOT enough tape and it leaked a bit. Tape, tape, tape.

Thanks, just an option if inserts or an aftermarket lower mount do not become available any time soon. The directions on the Eneggy Suspension Parts site are very detailed as far as using the urethane. I wasn't sure if I could post the link to their site. They are a supplier of Energy Suspension parts, not the actual E S page.
Nicely done!

Hopefully inserts will become available soon. I thought WMW was working on some but that thread seems to have gone quiet.....

Nice work. I've been hoping for some stiffer mounts, but this might be the answer

I am happy with the way it drives at the moment so I may skip the other 2 mounts. (assuming they have voids that can be filled ) With the lower mount filled on the Fiat it delivers the power from the engine direct to the wheels.
I purchased all 3 mounts on my Speed 3 and it is a bit too much. I plan on reinstalling the factory front and trans mounts, and leave the lower on the Mazda.
On another note, how is the tune going ?

The tune..... They got the base line and they mentioned something about another part to get into the ecu.. They are in the works of really pushing this thanks to every one blowing up their email requesting this .. I'm gonna do this when I get home.. Also dyno results of all these mods

I just got mine back together after letting it cure for a couple of days. Neat stuff, and definitely messy to work with. Second the let it sit for 10-15 minutes before pouring, and stir it often until then. Haven't driven the car with it yet, interested in seeing how it feels.

Mine feels great.. Did the motor mounts also .. Took for a little spin and I love it ..

Thinking of trying this but getting a new mount to work with so I can keep the original. The mopar parts site shows three different styles of mounts (see pic below).
Looks like the part labeled #6 is the correct one for our Abarths (bottom right). Can anyone confirm? Part # 68105215AA for the 2012, 68105215AB for the 2013 about $39 at moparonlineparts. Thanks!

Looks like #6 to me when I pulled mine ...

I changed the front and rear sway bars and did the mounts.. Now my flex pipe in the exhaust rattles do those things break that easy ?? Anyone else ever had that?? I can hit it softly and hear it rattle

Your talking about the mesh weave flex portion right? If that's what your talking about I have not personally seen one of those go bad. I do know that catalytic converters heat shields can sometimes start to rattle around the time they go bad. But looking at your signature looks like your running a custom downpipe so I would assume you opted to not run a cat.

Take the plastic skidplate off and double check that you reinstalled and tightened the bolt on the strap holding the exhaust to the bottom of the motor.

That's a prime concern of modifying the stock Motor Mount hardness... all that NVH has to go somewhere... and if it can't transfer through the mounts, then it starts transferring through welds/ flex points in the exhaust system.

Ok this came about after the rrm ecu and neuspeed bar install.. It's there I tried the skid plate but still makes a noise so put it back on.. It comes and goes with clutch movement .. Think the clutch died?? I really don't feel a diff in it.. Ill tear the car down and search around maybe it's a lose bolt.. One min it was fine and the next this weird noise

Drove the car for the first time after the rear mount mod this morning.

Pros: No shifter movement or vibration now. None. Even under acceleration it is smooth and steady as a rock.

Cons: Between 1-2k RPM it feels like your butt is connected to the motor. There is a very deep bass thrumming sound/feel till you get over that point.

So weigh your options here and be sure you can tolerate some additional noise/feel for the benefits.

Did you use the 80A urethane? I was thinking of trying the 60A as a compromise.

Yep, and I formed my tape mold to allow more of an overfill than the OP. Likely the softer urethane would be a better option for dailie use.

now if only one of our vendors would have a set of mounts made. 60a would be great. had 80a before and felt it was very stiff.

Finally completed mine. Thank you Daytona 500 for all of the initial work and writeup.
I thought I would put a video together in case others are interested.
I am very happy with the end result using 60A urethane.

Nice job with the video. With my looks and your brains.........

My mount is holding up well and I would still reccomend this to anyone that is modded. Just don't forget there will be some noticeable resonance at certain RPM's.

Can't stress enough that when doing this you need to use good quality duct tape. I learned the hard way and made a hell of a mess to start with. Well worth the time and money. Btw I also purchased a torque arm from the studio so down time was minimal.

Do they fit now? He was selling the European version as he does not have a US car to test on (he is primarily Mini).
The European versions do not fit our cars.

59FT/LBS for the E18 body bolt; 96 FT/LBS for the 18mm transmission bolt.Thanks once again. I just got a call from WMW and they said the mount I ordered wont fit.... They did say they are working on one that will. So between WMW, Neu and RRM mounts are on the way and should be here soon.
