Mazdaspeed 3: SURE Motorsports’ Rear Engine Mount Install
I received my new SURE Motorsports’ 2010 Mazdaspeed 3 rear engine mount the other day. For this installation I am using the 90 durometer urethane bushing that comes in blue. I will be driving with this installation for 1,500 miles then switching to the 70 durometer urethane bushing and I have a review on it now that testing has been completed. Until then, here are the do it yourself installation instructions for the 2010 Mazdaspeed 3 rear engine mount.
Where is it:
The rear engine mount is found under the car towards the back, middle of the engine bay. You must jack up the car to get to it. (1) Place the Jack under the big bolts connecting the subframe to lift the car then place jacks on subframe where you see my stands. Otherwise you risk denting your subframe. (2) I usually release the Jack (slowly) to let the full weight rest on the stands, then lift the Jack snuggly to the bolt and lock it for added safety. (3) Always remember to use something to keep the car from rolling. Even if the surface looks flat, it may not be. Safety first when working under 3,200+ lbs of car!

- 17mm regular and deep socket wrench
- 19 mm regular and deep socket wrench and wrench
- long socket wrench to get the proper torque to break the bolts
- Gloves

What to do:
Locate the rear engine mount towards the back of the engine bay connected to the subframe. (1) remove the 2 Bolts. (2) Remove 2 bolts and loosen the 3rd bolt so that the bracket frees from the engine mount and hangs down. (3) Pull out OEM engine mount and get your SURE rear engine mount. (4) Slide in the SURE rear engine mount with the logo facing towards the passanger side. It is a tight fit so don’t be afraid to use a little elbow grease.

(1) Use the Bolt to the right, the one with more threads and shorter. (2) Hand thread the bolt into place and do not tighten all the way at this point. (3) Now slide the screw provided by SURE Motorsports’ through the engine mount and bracket. You will need to pinch, wiggle and pull to get it to go through since the weight of the engine has shifted. Also make sure there is a washer before the 2 bolts on each end. Do not tighten completely at this point. (4) Start replacing bolts on bracket. Once again we have not completely tightened all the bolts at this point because you will need to push, lift and wiggle parts into place to slide the screws back into place. (5) Once all bolts and screws are in place begin to tighten them down. Start with the engine mount and work back to the bracket. Get them nice and tight but don’t break the bolts!

That is all there is to it! Takes about 30-45 minutes depending on your setup and experience working under the engine. Below are the parts you are left with.
