    Must Have!

    Posted by Unknown on 11th Jan 2016

    This is the best upgrade you can do the make your engine feel more responsive and secure. I have an 03 Mazda 6s. I ordered the 88 duro and have no vibrations to complain about. In fact I wish I would have ordered the 3 pack instead of just 1. My engine feels so secure and peppy compared to the oem mount. Plus I've been through 3 oem mounts so it was time to switch. Don't even bother getting the 70 duro you will love the 88!

    Can't Beat!

    Cannot compare the quality of the workmanship in these products. I installed 2 of their mount this weekend, and it makes the car drive incredible.

    Also, their customer service is great.

    Bought this after finding out that the rear engine mount on my 2004 Mazda 6 wagon was falling apart. Some searching later I found that the stock mount is often regarded as being a barely passable piece of junk, and, not wanting to have to do this job more than once I decided to go aftermarket. AWR was recommended on several different forums, so I came here to find the parts I needed.
    I went with 88 durometer after reading reviews on a Mazda forum that said the 70 durometer ones fall apart.
    Not wanting to have to mess with the other mounts which were also falling apart, I ordered replacements for those from ebay because the same forum I went to said that the AWR versions of the trans side and passenger side mounts were way too extreme for street use, and several members had actually gone back to a stock design for these parts.

    Since I just installed this today I have only early impressions. First impression is that the mount is much more streamlined, and of a much higher quality than the stock mount. Second Impression is that it is a bit difficult to fit into the stock mounting especially at the rear. On the recommendation of a forum regular, I used a prying tool to sort of stretch the mounting bracket open a bit. This made installing the back part a breeze. As for the front part, well, the engine had rocked around a bit while removing the old mount, so it took a bit of persuasion, from the prying tool to get things lined up again. That said, it was more a matter of getting myself into a position where I could see what I was doing than any real feat of strength.

    After installing this and the other two mounts I immediately noticed that there was a lot more vibration from the engine, instead of being sort of subdued and distant, the engine was sending a message straight to my spine that it was not just some lump of metal, but a living thing with a heart and soul.

    I drove for about ten miles and some of the harshest vibrations died down, leaving the feel of power, without the harshness. It's sort of hard to define. It sounds racier, more alive, than before. I'm not sure if this is down to just the rear mount being replaced, or more because all the mounts are new, but the whole car feels tighter. The transmission shifts a bit more smoothly than before, which is a blessing as it was getting quite sloppy, especially at part throttle between second and third gear, with the old worn out parts.

    I went to an abandoned parking lot across the train tracks and used my Torque app on my phone to lay down a few 0-60 and 1/8th mile runs. They were almost a second quicker to 60 and a few 10th's faster in the 1/8th mile. This was done with a full tank of 87 unleaded and a bunch of junk in the back... with less gas/weight in the car I think the improvement would be even more significant.

    I'm hoping that the vibration isn't too annoying at highway speed, as my commute is mostly 65 to 75 mph... Time will tell I suppose.

    Overall, at this point I'm thrilled with my purchase.

    The only downside I can think of is that the shipping was very slow. I ordered my parts 8/22/2014 and didn't receive them until 9/5/2014... If this had been free shipping I might have been more forgiving. I ordered the other two mounts from ebay on 8/22/2014, about an hour after ordering this one, and they arrived 8/29/2014, and came from two completely different places... so maybe if you're in a hurry look elsewhere... overall though it didn't matter much to me since I didn't have time until today to install these anyway.

    Last Mount I will Buy!

    Posted by Kirk Grier on 22nd Mar 2014

    Replaced two of the stock mounts in the 35k miles I've put on my 6s since I bought it. The AWR mount is extremely well made, fit perfect! I went with the 88 duro after reading reviews at mazda sites noting it will breakin a bit. I don't track my 6, but do like enjoy twisty roads. Immediately all that driveline slack is gone. Also changed fluid to Redline MT-90 while under the car. Smoother shifts too now. Quick "new car" feel for not much $.

    This is such a beautiful piece that you almost want to display it instead of installing it! VERY high quality and great fit. There was an initial mix-up on my order, but Tony corrected it ASAP. Thanks!

    Install hint: use the scissor jack from your truck to keep the engine from rotating after you remove the old mount. Simply place it between the lower front of the block and the metal cross beam at the front of the vehicle.

    Better, cheaper, strong and less expensive than OEM

    Posted by Daniel on 20th Dec 2013

    Considering that the oem mount on my 05 6s Wagon was hanging on by approximately 3/4" of rubber left holding it together it was time for a change. Rather than going for a replacement (that would share the same design flaw of the original) I chose this item instead. Not only is it beautifully machined aluminum with urathane on one end and 70 durometer rubber on the other but it is also way stouter in every respect than the original without any noticable weight penalty. Install was straight forward, just take care to make sure the bolts go in without cross-threading.
    Result-transmission shifts very well, no banging going into reverse and noticably improved accelaration from standing still. Want to add that vibration at idle appears to be same or just minutely more than stock.

    Very nice.

    Seems great so far

    Posted by Robert on 23rd May 2013

    I don't use the car much so I've only driven a few miles after installing the new 70 durometer mount. I noticed improvement immediately. It shifts smoother and clutch engagement is so much more controllable. My wife appreciates that.

    Installing was fairly simple. I expect this to last longer than the stock mount, which appeared to be replaced already at least once.

    This one is too pretty to be under the car!

    As advertised - Great!

    Posted by Jim on 22nd Apr 2013

    Quick shipping, easy install, good fit. Wasn't sure if I would be able to tell the difference - I can definitely. The OEM mount was trashed, this was a great replacement.
