What exactly does the snub mount do?

[Baggio]

I had my stock snub mount replaced with an 034 snub mount when I had my crank seal replaced yesterday. 1/2 of my stock mount was missing. It was totally blown/shot. But, the question is what exactly does it do? I haven't felt any difference in the car after replacement. Am I supposed to noticed a difference?

It's basically another motor mount. The biggest thing you will "feel" is slightly more vibration in the shift knob (for a 6MT), and perhaps slightly crisper shifting since the motor can't rock or move as much. I put the Apikol in mine and didn't notice much other than the shifter vibrating a bit more than before.


APR's wording:

"...replaces the front engine mount on the car. This mount enhances upshifting and downshifting, reduces driveline shock, and helps power transfer by taking up excess drivetrain slack."

I have a Tip, so I guess I won't feel any vibrations. I guess I should test the paddle shifters to see if the shifts are more smooth.

It basically locates the front of the motor and prevents it moving up/down, left/right. A few weeks ago I did my serp belt and found that the ARP snub mount bushing was totally missing . For the previous couple months I had been getting a "clunk" on faster shifts and really thought it was the diff mount. After installing a new snub mount the shifts feel much better but I do get a bit more vibration through the shifter.

If you are in there doing the serp belt it is a worthwhile mod but I am not sure I would go through the hassle of doing one if I was not in there.

Cheers,
Jim

Serpentine belt, crank seal, snub mount, and oil change were all done yesterday. With a Tip, in D it shifts at 2200-2500 RPMs. I doubt I would notice the difference. I need to put it in manual mode and and shift at higher revs to test it. I think I may drive it this way as i am not seeing any better gas mileage in D mode. Lol.

You got the 034 snub mount that is cut a millimeter smaller so that you don't get vibrations like what would happen with the Apikol snub mount. I put the same snub mount on my mother's A4 for driveability.

As others have said the snub mount makes for smoother shifts by holding the front of the engine in place.

Thanks for the input. Didn't know there was a difference between the 034 and the Apikol. I just read JHM's website and basically flipped a coin between the 2 mounts because they seemed about the same from the description. Lol

I didn't know 034 was cut a tiny bit smaller. I put an Apikol in mine and honestly don't even notice any vibrations

Doesn't 034 sell the Apikol? I didn't know they had their own.

My 2 cents.... It makes going over bumps more jarring.

I think it's the luck of the draw (and proper installation). In my case, i couldn't align things without some interference between the snub mount and the metal part it is contained by. The interference causes some vibrations. So i ended up shaving off ~1mm of the Akipol to remove the interference (didn't know that JHM's was already smaller). If statically you can align things without any physical interference, you'll be fine from a vibration point of view, IMHO.

The way I think about it goes something like this: the engine mounts support and prevent the engine from twisting around the crank, like when you rev the engine with the hood open and you see the engine twisting. The snub mount doesn't support, but prevents the engine from rocking back and forth on the engine mounts. So the engine mounts prevent twisting about the rear driveshaft, and the snub mounts prevent twisting about the front axles. The trans mount mostly supports, taking some of the weight off of the engine mounts, but it also aids in suppressing pretty much all engine movement.

I have a tip with the 034 Snub Mount and 034 Zero Gap bracket. You won’t feel much through the shifting (or indeed the paddle shifts) but you will feel more vibration through the car itself as the fit is so tight the increase is via the chassis.
I mentioned in an earlier post, It reminded me of the old Ford Falcon 351 V8 Shaker I used to own. I know people are quite determined not to feel any vibration at all, but I find it not entirely unpleasant. IMO you feel a little bit more attached to the drivetrain.

Incidentally, If there is a small misfire or uneven idle (especially at cold temps) you can feel this quite redily via the pedals.

Well, after further review, I am not feeling any additional vibrations. Using the paddle shifters and shifting at a higher RPM seems to be a bit smoother and not as harsh as it with the torn stock snub mount. Oil leaks are now history. Crank seal fixed the the leak at the crank and I stopped the valve cover leaks by tightening the vale cover bolts. I am sure I will end up doing the valve cover gaskets eventually, but right now they aren't leaking anymore.

Keep in mind the ideal way to install a snub is to snug the bracket into the core support, re-assemble the car, start it, turn it off and then torque down. This will alleviate any 'tight spots' or pressure against any one wall, which is generally the cause of vibration post install.

They do sell Apikol mounts that they do not make, however the snub mount & bracket are not one of those parts. I'm REALLY happy with my 034 zero gap snub mount & track density line mounts!

Due to newton's third law, the engine/transmission will try to rotate about the front axle axis when under load. The snub mount limits this motion.

Because science.
