Which motor mount?

It seems there are several options for replacing the stock motor mount:

-Cobb inserts
-Street Unit
-TRZ
-CP-E.

Can anyone say which is best? I'm not crazy about additional NVH.
 
CORKSPORT inserts will probably feel most like stock, but still a big improvement. CPE is supposed to feel like stock too, but it costs a lot so that may be a factor as well.
 
from what i've read the SU seems to be the best tradeoff btwn performance & vibrations....mine is on its way, if I get around 2 putting it in netime soon I'll let you know
 
I swapped a 15k mile AWR 70duro out for the TRZ poly this morning. Huge improvement in feel, much more solid. So much so that I would never go back to a softer MM. Vibes are slightly noticeable, and I bought it used so it should be broken in
 
TRZ for sure. AWR's break way too easy. SU mounts have shown a few failures on this forum in the past too. the cp-e uses rubber instead of poly. they think it is a genius idea. i think they are morons ! there is a reason every other company uses poly for their upgrades. if rubber was better wouldnt places like energy suspension use it ?? its just another cp-e ploy to say..."look at us we are different " TRZ is tried and proven.there have been over 300 sold and not 1 failure !! most say they dont even notice the vibes after a short while, but some are overly sensitve and want no added vibs.
 
I got the brand new style that AWR produces...and it is GREAT.

Alot of the after market mounts start to tear because they are not snug...AWR makes a lip with theirs, and it sits nice and tight inside the housing.

I noticed much better shifts, but very minimul vibrations when idling at 800 RPMs and below.

Great product
 
I had a TRZ and wanted to take it out for a few days just to see what i was missing and it turns out that the mount wasn't quite right. One bolt came out fine and the other was difficult. Then when i went to put the stock back on i saw the horizontal bolt just wouldnt go in. I saw it was stripped. I thought i was a big idiot and did something stupid. But after a while i saw that the nut that was welded on to the mount was slightly offcenter but, it was only visible when i looked closely. So i somehow managed to get it on in the first place and it stayed on for a few months. I guess once i tried to put the bolt on again it was too stripped. It was difficult to put on the first time so i should have taken it out and checked then. I ended up needing to get two new bolts and a new mount from the dealership. I'm sure this is a rare occurence and i'm just about positive the issue was due to the mount but i'm sticking with my stock.
 
I installed my Corksport inserts today. Literally a 10 minute job once you get the car jacked up. I used a garage lift, so it took me longer to actually get the car aligned on the lift than it did to install the inserts. Take the 19mm bolts off the tranny mount and it's an easy job.

Impressions... feels like stock, although throttle response is better and it seems as though it breaks the tires loose alot easier when I lay on it in 1st and 2nd. Torque steer seems to have gotten a bit worse with the inserts, but it's managable. I have to drive it some more, but overall, for $35 and 10 minutes install time, it's a no brainer.
 
so one can do this themselves? can this work be done with regular car jacks (3 ton jacks and braces)?
 
very easy install. You might want to have a 2nd person if you cant rock the motor to get the mount out. But I have seen some MS3s that are very easy to do and some that wont budge at all. But still easy to do in your driveway.

I got the Corksport inserts as I dont plan to go wild with my mods. Sitting with only a few mods they feel really nice and work exactly as I needed. You might want to concider one of the full replacements if you plan to go a little wilder with your mods.
 
nah, i just plan on an CAI, a short throw shifter and the bushing and motor mounts....pretty much it for a few years. thx
 
the cp-e uses rubber instead of poly. they think it is a genius idea. i think they are morons ! there is a reason every other company uses poly for their upgrades. if rubber was better wouldnt places like energy suspension use it ?? its just another cp-e ploy to say..."look at us we are different "

The CP-E definitely won't fail, and it also performs almost just as well as my TRZ Delrin (which I still have), with absolutely no vibes.
