A JBR mount. I think it's an 80 duro, but I honestly cannot remember. I bought it from a NATOR brother.

Responding to an earlier post in this thread: Yes, raising idle rpm to +200 will do wonders for taming the increased NVH (vibes) that come with stiffer mounts. Also helps to reduce risk of "smoking turbo" if running the stock turbo.

Any insights on whether or not that cut into your MPG's?

I've always wondered by our idle is this low, I've seen it dip down towards ~500rpm imaginary mark.

The tuna set my idle at 850 (due to 3.5" intake) and it did not appear to change my fuel economy, or at least not appreciably. Frankly it didn't really appreciably change the vibes either, but my setup is pretty soft for aftermarket so it wouldn't be real surprising for it to be not noticeable.

You let a fish mess with your idle?

Did you eat it after it finished your idle?

Some tunas are good enough that it might be worth eating their meat, or at least handies and butt touches just to ward off that ole ZZB.

It seems to be no different. I made the idle increase about eight years ago, though and I have a heavy right foot.

Hey y'all, if you guys are wondering why there hasn't been any update on my experience with the Damond PMM, it's because they're out of stock for (at least) the next two weeks.

So they actually told you "two weeks"?

That's why I said (at least) two weeks. They said 2-3 weeks.

Honestly, I was a bit annoyed because there's nothing on their website that says they're out of stock. Also, they did not tell me they're out of stock until I asked them about my order 3 days after it's been sitting idle.

Not impressed with Damond Motorsports' customer service at all.

Bah. It would only have been funny had they literally said "two weeks".

I mean, it's not hard right? You're out of stock, that's ok.

But you couldn't let your customers know? You had to wait for them to ask just what happened to their money and why the order is sitting the idly?

Absolutely. It should not be difficult to setup the website to display quantities remaining. Just update it everytime a shipment comes in :boggled:

Yes, it's so easy! You guys already know how to do this - you should start your own aftermarket parts company.

Customer relations is a priority for any B2C (and B2B) business. If you haven't figured that part out, then it's not a sound business.

I haven't faulted them for running out of stock. Sometimes you don't get all of the necessary components to assemble a quality part, nothing wrong with that.

But informing potential customers, and displaying an *OUT OF STOCK* disclaimer is not hard at all. I mean, they managed to set up an entire, fully functional website, haven't they?

Oh ok, so sure, you can't display an "OUT OF STOCK" disclaimer. How are customers supposed to know they won't receive a delivery within the appropriate amount of time? Oh I know, let's email these people who placed an order, and inform them of the situation!

No? Let's just keep our mouths shut until they contact us about what happened to their money days/weeks later. Sounds like a good business plan Damond Motorsports.

So far I've noticed all the vendors sites operate this way. A few times I ordered from Corksport (part was on backorder but I didn't know) and went ahead and placed my order. The next day I received a call from them letting me know it would be a few weeks. I canceled at that point. When I ordered their turbo it was the same deal, but I wasn't in a rush so I was cool with the 3-4 week wait. But I always got a call within 24-48 hours letting me part was backordered, so I can understand your frustration. I also said the same thing to CS about adding a quantity counter on their parts for their website.

See, that's fair game if they call you after and let you know what's going on with the order. Because they told you on the website itself, or post-purchase follow-up, you were informed of the status of your order/money.

I had to call them after nearly a week of zero communications from them. It was only then that they told me the PMM is out of stock. However, unlike your previous situation, my PMM has failed, that's why I wanted the part ASAP.

I might play a bit of a devils advocate for a minute here as I just replaced my Stage 2 RMM after 4 years as the bushing had developed a tear. It was nice to have a compliant vibration-free mount, but the engine was moving as much as the OEM mount by the time I replaced it.
I asked CP-e if I could just buy a replacement bushing but they weren't much help so I just bought a whole new (Stage 1) one.

This gives me quite a history of rear engine mounts over the last 7 years.
OEM - Corksport Inserts (IMO, highly underrated) - SURE REM (Replaced after all the failures that happened, mine was fine) - CP-e Stage 2 (Bushing failed) - CP-e Stage 1 55 duro (Installed yesterday)

I have now swapped back to a stage 1 RMM for a couple of reasons. Mainly, after I installed the stage 2 RMM I found my car started popping out of 4th gear under heavy downhill braking at the racetrack. This also coincided with a switch to semi slick tyres so I never genuinely had a chance to prove that this was the cause, but my mechanic made a good point that since the bushing orientation had changed, it may have altered the way the entire engine moves on its mounts. The design may seem to make much more sense on paper, but there are reasons why the manufacturers do things the way they do.

I know it's an unproven theory but it resonated with me. And now that I am back running a S1, we will be able to test this theory properly real soon.

Here is a video of what happens when you pop out of 4th gear and have no power to pick up the weight transfer on corner exit. Just watch the gearstick.

Also here are some pics of my Stage 2 RMM that I just pulled off my car. Bought it in 2013, it's done 60 000km and about 25 track days. It's served me well but I am happy to go back to the way the gods (designers) intended. This design is sold on the premise that the bushing will last forever but that's clearly not the case. So if I am gonna be replacing parts, I would rather keep it cheaper.

Thanks for the reply, it seems you experienced exactly what I was in that it seemed like there was no difference in engine play. Do you have the other mounts upgraded or just this one? I do like the idea of the S2 and it makes a lot of sense to have it over the OEM one but the full benefit isn't happening for me. I don't track/autox this car yet because it's my only car but I'd like to get out there. I was expecting a lot more from this mount. I've read the inserts have a lot of vibration and I really didn't want that since I have to drive this every day.

It's an engine mount. I don't know what you want from it exactly but it was never going to change the world. All aftermarket ones cause vibrations but they also settle down with time as the mount beds in. I just have the rear one rest are oem.

I'd be willing to put money on it not being the mount. This is probably the same as the classical autocross 2nd gear popout. Probably you need a lighter shift knob and linkage weight.

Yea I'm inclined to agree, that's why I didn't replace it for 4 years. Hopefully my new turbo setup will be done by the end of the month and I'll be able to test it on the 1st of September.

I think that's your problem right there. lol My FMM made for a great addition. It's a shame they don't make them anymore. Only downside is it would fuck your FMIC plans. :/

Well they supposedly warrant it for life but I have never heard of a self-replacement bushing. Usually they tell people to send it back and they replace it. I presume you weren't willing to do it that way?

They did offer to fix it but I live in Australia so didn't want to go without a car for a month while the thing shipped. I just wanted to buy a bushing from them but they said it needs to be pressed out/in, which I am perfectly capable of organising myself but they didn't seem to want to trust me with that.
Once I removed it I unscrewed the flange and the bushing came out by hand very easily so even if it does need a press it probably doesn't need a very powerful one. My money is on a big vice being enough.
In the end it just became too difficult.

Checked in with Damond Motorsports and emailed them about my 2 WEEKS OLD order.

Loving the lack of communications from them.

Fair enough. Didn't realize you were in Australia, yeah that changes the equation some for sure. And yeah from what I've heard it (the bushing switch) is not all that difficult. I'm guessing they're sensitive about it because of the damage they took when the retainers were coming out.... though they still have a TMM that they ask the user to assemble with threadlocker AND they have an anti-backout plate. Seems strange to trust the users on the one hand and not on the other. But oh well, companies' policies often aren't really rational like that anyway.
