yea uh that motor mount has been out for a while...at protegegarage.com....they just had it labeled for the mazdaspeed, but since its the same motor the mount fits anyway. But congrats on the buy anyway.

they look good. you had better take pictures of what they look like on the car 

i know theyeve been out for a while. i checked protege garage and i didnt see this type of there.. they had a different one. and actually i read reviews about that mount. some said that mount could break easy. i havent read ne negative reviews about this so i went with this one.

had mine for a while.  I would post a pic but it's on my busted up computer.  Rides rough though bud.

thats good to hear. i just dont wanna go thru my break-in period. gonna make my car vibrate like crazy for the first 1000 miles. oh well.. my girlfriend will enjoy it  lol.

lol haha your girlfriend will enjoy it. generally you have to go through it even if you really dont want to. just like when i first bought my car i couldnt surpass 4000 RPM and couldnt use my cruise control. which really sucked cuz i like cruise control. but think of it this way. after it you will feel alot better about it and wont have to worry about it unless something breaks

 If it's any consolation SDeeD, my AWR (77 durometer) was pretty rough too.  It used to REALLY get on my nerves especially when the A/C was on, but it has settled down a bit now after 10K miles. The change over to the MS CAI seemed to help a lot w/that too.  To my surprise, that seemed to smooth out a lot of the engine vibration I was experiencing both before and after the AWR was installed.
 
 

thats the one they have on www.protegegarage.com . the AWR was reviewed and some claimed that it broke on them. it was took weak. thats y i decided on the SU mount. but 10k miles is LONG way to go to break in the mount. reviews told me that SU breaks in around or after 1k miles.

No problems w/breakage at all.  I don't know how it could unless there's a weak weld.
I may not have put quite that many miles on the mount yet either.  I'd have to check the records still on my other computer to be sure.  But the point was more that the CAI I only recently installed smoothed out my vib by quite a bit.  I noticed that right away.
 
 

i just looked up the differences between streeunit and protegegarages mounts and basically they both do there jobs but since streetunits mount comes with only one durometer rating its also lower then protegegarages lowest one but the only thing i couldnt find out was what the AWR mount was made of not only that but the AWR mount is only one peice while streetunits mount is two peices so i dont know how a two peice can be stronger than a one peice other than they may be different materials?

As the owner of an AWR mount, I can tell you sincerely that it's polyurethane.  They come in either a 77 duro, or an 88 duro.  I have the 77 which is quite enough for me on the street.  However, besides the difference in material, some of it's strength comes from the fact that the bushing itself is smaller in diameter.
Please observe....


 
WOW!!! Post #1100!!!  Whoo-Whooo!!

took the picture of the original and the new one. how hard were you one the 1st one. it looks like crap lol

Ok first let me appologize for my badly written previous post, my buddies laptop's shift key was stuck down so it was either write in all caps and look really stupid or just keep putting the word "also" to get the line, and the connection was pretty crappy....had to rewrite that about 3 times, anyway Virgin1 what i was wondering was the whole AWR mount poly or what cuz i know that the bushing is composed of poly i just didnt know what the acutual mount was made out of. I know that SU's mount is made of billet and the insert was also made of poly, but the strange thing about there mount is not only did they opt to construct the mount out of two peices but made the duro so much softer tham AWR's mount. 

Statement from the product listing:
 
70 Durometer bushings are not recommended for this mount on the Mazdaspeed3. Aggressive driving on the 70 Durometer bushing may damage it. 88 Durometer is highly recommended if purchasing this mount for the Mazdaspeed3.
 
i remember reading about the AWR mount somewhere. somebody was claiming that it broke on them. ill search for it, hopefully i'll find it again.

is that the stock mount on the right?

OK, one at a time, from the top.  (I am a former drummer/musician.)
 
Jaime, that is the OE mount and it had roughly 25K miles on it when I switched it out for the AWR.  It's dirty only, not broken.
 
Tracker, The AWR housing is made of stamped steel and appears to be exactly like the original (a modified original piece, if you'd ask me.  No difference, except...) except that the center hole for the bushing has a new piece of steel welded into it that was re-machined smaller for the new (smaller diameter) poly bushing.  Look at the picture of the AWR and you'll see what I mean.  If it was gonna break that's probably where, but the weld on mine looked perfect when I inspected it, and I did inspect it completely before the install.
 
SPeeD Man, See my reply to Jaime for your answer.
Also, in reply to your other post, I don't understand that thinking as the 77 would be more flexible under load than the 88 absorbing more of the flex & torque?  It seems like a simple case of the "mighty oak breaking in the wind vs. the forgiving Willow that bends, instead of breaking in the wind " to me.  I would need more of their reasoning (answers) to be convinced of that.  And, by that token, Tracker states that the SU is actually softer than the 77 duro AWR.
 
 

OK i installed the engine mount, and i gotta say i can feel the difference!!!! the throttle response feels so much meaner. i can feel the engine vibrating a bit, which doesn't bother me, buttttt i love how i can also feel the exhaust roar under my feet! lol.. and wheel hop is a thing of the past for me nowww!!! but one thing that bothers me is that i had gone through the dealership to replace the FIRST stock engine moutn (which broke because of the bolt). my friend who changed the mount showed me how the bushing on the SECOND stock engine mount (the one that was newly put into the car) was cracked. pictures are below. im probably powerless to do anything, but could i / should i show this to the dealership for any reason?

sorry about the bad quality pics. it was taken from my camera phone. it works better far ranged!!!

Hmmm.  That would certainly make me worry if I owned an MS3 w/stock engine mounts.
 
Just my .02, SPeeD, but if I were you I might go directly to Mazda USA.  Write to them and include, or offer to include, the pictures.  See what they say. 
IMO, dealers are more likely to go with their gut reaction which could range from, "Oh my God!!  This is dangerous and poses a hazard to any owener of the MS3!! We should contact the regional rep and report this." to "So?  What do you want us to do about it?"
See what I mean?
 
 

and how do i go about contacting them?

hi.  its time to replace engine mounts for me.  what is the durometer of the stock mounts?\

i think ive figured out the durometer of the stock mounts to be 62 durometer.
the street unit after market side motor mounts i am looking at are rated 62A durometer.  does the A imply anything different from stock the stock rating?

ive figured out what the A means for durometer ratings.
there are two different durometer scales, A and D.  the scales refer to the amount of mass applied and the resulting force of the material to the mass.

haha im answering all of my questions.
but please share your opinions on awr racing mount, street-unit mount, and cp-e mount.  THANKS!

also, how many engine mounts are in the 3? are there 3 mounts?

im currently looking at street units transmission and cylinder head motor mounts rated at 62A durometer and also at awr-racing rear engine mount rated at 70 durometer.

any comments about the items listed above or any updates the the performance and reliability of the parts?

ive also stumbled upon a motor mount made by cp-e.

your opinions would be greatly appreciated.

Jeez.  You coulda'' had my 70 duro AWR for $45 shipped!! I had it FS here for over a month but no one showed any interest.
