here for info on motormounts

Thats pretty much it.

I suppose it would help to provide info on the car:

2008 Mazda3 hatchback. 138k. Picked it up a week ago. I used to have an 06 2.0l sedan which died of cancer.

I do have plans to put some mods in. I have an SRI i am moving from the old car. I've also installed LED foglights. But beyond that, I have little interest in spending money on upgrades.

I am inclined to use the factory motormount, but ive been reading that the factory mounts are notorious for being pretty bad. But I've heard that there are better urethane inserts, maybe you guys are familiar with this?

For anything except frequent spirited driving or track use the OEM are still the best choice. Look how many miles on your current car with what I presume are the original mounts unless you post other information? Most information about prematurely failing or poorly designed engine and transmission mounts are not back by any real statistic's or empirically posted information ....anywhere!
After this came up on this very forum the last few times going to the TRACK (MAZDA RACEWAY aka Laguna Seca )I talked to owners and look at many MAZDA's, stock, modified and full track use only and most all used FACTORY mounts

Polyurethane inserts into the factory mounts with any platform produce unpredictable results.
Most all Polyurethane mounts will give a noticeable ride quality change towards firmer and plastic interior parts will let you know where they are.
Also what many do not understand is you should changes all the mounts and not the ones that are easy to change when upgrading from a OEM to an aftermarket Polyurethane mounts.


Good luck with your project!

There's a TSB for motor mount replacement. I've done all three of mine, after my PSMM utterly failed, and my transmission mount nearly so. The rear motor mount really wasn't in any better shape. Luckily, changing them is a piece of cake, and during an oil change is a great time to do the job, because you already have the car in the air, and the bottom cover off anyway! Most of your work is done!

For the PSMM, I went with a $40 one from RockAuto. It's lasted me about 60,000 so far, and no complaints.

For the rear, I went with a 70 durometer AWR. It added a bit of NVH (noise, vibration, and harshness) to the ride, but it really firmed up my 2-3 shifts in my manual car. It's been on there for 5 years now, and other than the increased NVH from stock, no complaints. Honestly, if my PSMM fails again, I'll replace the AWR with an OEM one again. I'm getting old, and when I was still in my 30's, the NVH was cool. I'm 46 now, and like me, that shit's getting old.

For the transmission, I *just* did that one. I went with the latest "D" revision of the OEM mount from Cox Mazda. It was $20 more than RockAuto, but I have found that OEM parts are generally of much higher quality than "OEM quality" aftermarket stuff. For $20? Meh. Why not get the OEM? The replacement is slightly more complicated that the super easy PSMM and rear, because you have to pull the battery and battery box. You cannot see the mount to inspect it without doing this. Also, have a strong as hell impact wrench or really long assed breaker bar to get the main bolt off. That bastard is ON THERE. When you put it back on, don't forget to use thread locker and torque to 90 ft.lbs. You DO NOT want that bastard coming back off on you going down the road.

If I were you, I'd go ahead and change all three. If the rear or PSMM fail, it sucks, but no real way to damage the car. If the transmission mount fails, it can really screw stuff up, because at that point, the only thing supporting your engine and transmission on that side is the CV axle! NOT GOOD.

Best Motor Mount setup for wanting to keep OEM feeling...

Purchase the EFocus Rear Motor Mount

Purchase a solid rubber Passenger Side Motor Mount

Tranny mount just either buy OEM or Aftermarket OEM style.

Who makes a good solid rubber PSMM? I read that a lot of folks used Roca/Rocar-USA and really liked them. But last year I couldn't find any of their mounts for sale. Seems like they stopped making them? A PSMM from them was $73, and a full set of mounts was $139.

Looks like Rocar-USA mounts are available again from Sparktec Motorsports! They have them for both the 2.0L and 2.3L engines for '04-'09 Mazda3 cars.

If you go that route, make sure your dental insurance is current!

After you posted information about hardness of bushing you should know that a solid rubber (common on many pre 90's cars) mount can be as soft as a fluid mount but when going softer then 55 (depending on what scale you are looking at)you lose torque applied support.

Only way to really learn is to actually measure stuff.....

I actually have a couple design proto-type that uses a very soft durometer polyurethane and an adjustable stop dampener. So you get the best of both worlds.

Any PSMM without the liquid filled version will do...I for got what brand I got though...Make sure you buy them w/ the Aluminum bracket included!
