James Barone Racing Rear Motor Mount: 25,000 Mile Update

I can’t believe it’s already been almost three years. I’ve now driven a total of 25,000 miles on the James Barone Racing rear motor mount, so I thought this was a good time for an update.

** You can view the original install and review post here. **

I’m still happy with the mount, but there has definitely been a degradation in the mount’s firmness. Minor wheelhop has returned, and front end traction,  especially under acceleration, has decreased. In addition, shifting is less precise. A positive effect of the mount’s reduced stiffness has been a reduction of NVH (noise, vibration, harshness) inside the cabin.

I would still highly recommend this mount to anyone interested in improving the firmness of their Mazdaspeed 3’s drive line and preciseness of the shifter. Even with firmness degradation over time, the James Barone Racing rear motor mount still performs far better than the stock unit!

  1. Hey there, I read both your original review as well as this one. I own a mazda 3 n/a and was looking into the jbarone rmm. What was the stiffness on the one you have? 88a?
