DM PMM Install

Redline

I done fucked up for the last time.
BANNED
All prepped and ready to go for the PMM install tomorrow, weather permitting:

Be on the lookout for a JBR 80d PMM in the F/S section. Last time I checked, it's in great shape and I'll try to offer a good price.

Install pics and driving impressions to come...
 
Just got my JBR trilogy sold, there are definitely people out there scooping up used JBR mounts.

Patiently waiting your results. My tax return should be here in a few days and I'll be ordering DM mounts as well. I'm getting excited seeing all the positive reviews from everyone who has switched over.
 
Hopefully you don't cross-thread the frame bolts. Turned a 15 minute job into a 2 hour ordeal of swearing and baby punching.
 
Installed today. To prepare, I used one low-profile jack to lift up the front side of the car a few inches, doing so from behind the passenger front tire (lowered car problems FTW!) . Then, with the extra clearance, I used another jack to support the oil pan from underneath with a piece of wood between the jack and the undertray (which I didn't bother removing).

1) I used two picks to get the pesky coolant tank tab on the backside loose (the one nearest the strut mount). It's a lot harder to remove than the other retaining clip:

2) Extensions and a breaker bar saved my butt. Don't want to crack an A/C line!:

3) After getting the old mount out, and new mount in, I tightened everything down pretty snug, but didn't torque it yet. For reference, here are the torque specs and sequence to follow:

4) After snugging everything up good, I released the jack from underneath the oil pan and then torqued to spec. It's pointless to torque if the engine is still supported from beneath and the mount/engine aren't sitting as they naturally would. The mount's in its new home:

5) I started the car and let it idle for a few minutes, revving it up and down, and also holding it at about 1.5-2k rpms for a while (the range I usually notice the greatest amount of vibes). After this, I turned it off, removed the jack from behind the front passenger wheel, and re-torqued everything to spec again.

All buttoned up. I'll offer some driving impressions after I get a good deal of seat time and adjust to the "new normal," but I will say this: when sitting in the car and idling in the 1.5-2k range, I still have a good amount of vibes in my rearview mirror, but they are much less. If I had to quantify it, I'd say maybe 1/2 of what I had with my old PMM. We'll see what happens as I get used to it and the mount breaks in. So far I'm very impressed with the mount. More to come...

Indeed! No cross-threading for me. I made sure the holes lined up really nice before hand tightening everything and then using sockets to snug them down. My Dad told me a long time ago, "if a bolt/nut doesn't want to go in, DON'T FORCE IT!!!" Sage advice, haha. I adjusted the engine-supporting jack height a tad during the install to get everything lined up really well. That made everything go in hand-tight very easily, and prevented any cross-threading. Work smarter, not harder, right? LOL

Initial driving update: WOW, what a world of difference coming from the old PMM to the DM PMM! It's basically brand-new since I installed it yesterday, but vibes are much lessened and shifting feels noticeably more precise and satisfying. I made ~20 mile round trip to school and back (full-time grad student), and I was very impressed. Since it's so soon, the placebo/imagination effect may be part of it, so I'll post more updates as miles accumulate. But it definitely felt like a very noticeable positive difference today. I'll be interested to see how things change as it breaks in.

Not placebo...had plenty of opportunities at fall dragon camp to switch between Damond mount equipped cars and JBR mount equipped cars and the Damond ones are quieter.

Dat celestial blue doe.
 
I, too, can attest the the Damond mounts are much, much quieter inside the car compared to JBR. I put ~50 miles on my new Damond mounts yesterday and will be writing up a full review after a little more drive time. So far they have been fantastic.
 
I bought my speed used with all three Sure Motor mounts and the Vibration/Noise is literally insane, i ripped the whole car apart dashboard and all, to try and quite the car up. Wondering if the Damon mounts are going to make my life worth living, the car is making me mental.
 
Sure bushings are shot. Replace all mounts, send me them to put on the Wall of Shame.
 
Honestly they still seem stiff, from inside the car. It may be a totally different situation once i pull them off. In its current state i can barely use the review for anything, at idle, reversing, or highway speed under 80mph. If the ac kicks on its sounds like an M60 is going off just outside my window.

The bushings have died of AIDS.

Go Damond fully mounted if you want exceptional performance. Or, if you want less NVH, at least get their RMM and maybe even the TMM, if you don't mind a little more NVH, but don't want fully mounted NVH. Having all three mounts, I am VERY pleased with the performance, which I definitely need at my power level. Best mounts I've ever run, and my Speed is still very DD-livable.

Sounds you the Sure bushings decided to exit the vehicle. At least, something maybe seriously wrong if your experiencing that type nvh from motor mounts. Get the Damond and don't look back. Use Sure mounts as paperweights

I'm thinking just replacing the mounts and keeping them in the car to throw out the window at deserving passersby. I figure they were only designed to infuriate people any way, so why not give them one more shot.
