JBR Rear Motor Mount Chromoly 88A Mazdaspeed 3 2007-2013

This upgraded mount makes a world of difference in how the car feels. Shifting gears , and accelerating feel much more solid, and composed. Minimal vibration and noise increase. With how easy the install is, and the low price; this should be one of the first mods to your Ms3.

If you want to feel into a race car, take it soon. The vibrations are very present by I don't dislike it. The shifter, the wheels hop, etc....all is better now :).

88 duro meter, does everything it's designed to do. Heavy vibes for the first 50 miles. Only issues I had was install, bolt holes was off 1/8 inch or so... slight difficulty installing. Just use a pry bar don't be a p***y.

Bought this to replace my junky stock motor mount. Bought the 88. Very impressed with the quality. After the install i took my car out and spun my tires in 3rd gear. I was blown away. no more wheel hop either. My shifts are now super smooth and I have no more clunking while shifting with spirited driving. The vibrations were a little rough for the first 50ish miles but its no big deal. Well worth the price for what you get. You won't be disappointed.

The JBR RMM is a great mount for the price, construction is top notch and shift quality is much improved. I was worried about increased vibes and noise since it's 88 duro, but while there was an increase it was barely noticeable and well worth it for the increased performance!

The 88A durometer JBR RMM is no joke. I upgraded to this mount from the stock wet noodle of a mount that came with the car. The vibes are definitely noticeable below 2k RPM and when the A/C is on, but if you are going to complain about vibes (very little at that), then don't buy this mount. You bought a beast of a car.

I bought this mount, because of torque steer, wheel hop, and mushiness that I felt from the motor. All of that was eliminated and more (#becauseracecar) by this motor mount.

Either have a friend help you or get a shop to install it for you. I messed up a socket installing this, so I had a shop tap the socket and install it for me. Make sure you torque it down to 70+ ft/lb of torque as this part receives a lot of engine stress.

Overall, this is a solid mount that brings your car to life and makes it easier drive. Have fun with it! I love it!

This is truly the best!
I had a cpe 1st time and it was ok but i think it was kind a soft for the lunch control. .then 2nd had a SU brand for aggressive driving it was great at beginning but after about 3000 miles it got kinda soft too , so i wanted to give this one a try..so far its the toughest..hope it will last. NO wheel hops anymore. forgot to mention that the previews m mount when i head hooked up with access port tunner started to hop again..much torque added..but Not with this one so far..

Love the the way this rmm makes the car feel and only took 5 mins to install.

Wheel hop eliminated, just the right amount of vibes (i.e my teeth aren't rattling), crisper shifts, great overall feel.
