The JBR Passenger Mount is the only Vertically Oriented mount on the market. This mount can and will handle all the abuse you plan to throw at it. From street to strip it’s the only true 1 piece Passenger mount for the 07-13 MAZDASPEED 3. They’ve replaced the weak cast aluminum factory support which has been prone to cracking with a steel support. The actual mount itself is CNC milled from a solid 3 pound block of T6-6061 grade aluminum.Custom, Proven Poly Urethane bushings in your choice of 70 or 80 Durometer allow you to choose the amount of stiffness you want to run without sacrificing comfort.

First things first, we need some tools. Here’s a list of all the tools you will need to perform this installation:

1) Jack, Jack Stands, Ramps or Lift
2) Ratchet Wrench
3) Torque Wrench
4) 17mm Socket
5) 10mm Socket
6) 11mm Socket
7) 11mm Wrench
8) Flat Head Screw Driver

To begin, if you don't have access to a lift ensure you park on a flat leve surface with the e-brake engaged and toss some wheel chocks behind the rear tires.
Remove the under tray so that you can support the motor with your floor jack before removing the motor mount.
**You do not want to apply a ton of force with the floor jack or you will break something. It is simply going to be used to take the load while you pull the motor mount and put the new one in**














Remove the coolant and power steering reservoirs by inserting a flat head screw driver in to the tabs and pulling up. *NOTE* The reservoirs can be pivoted by their hoses towards the front of the vehicle.

















Remove 1 x 10mm bolt for the ground strap, 2 x 17mm nuts and 2 x 17mm bolts from the mount and remove the mount from the car.

















Remove 1 x 10mm bolt and remove the ground strap.





Bend the end of the ground strap previously bolted to the mount on a 45* angle.





Flatten the tab on the end of the ground strap previously bolted to the chassis.





Remove the 8mm timing cover bolt located towards the rear of the vehicle above the alternator. Attach the end of the ground strap previously attached to the factory mount that you bent on a 45* degree angle in the step above and tighten. Attach the other end of the ground strap using the 10mm bolt removed in step 6 to the rear most pre-existing hole in the sub-frame located in front of the alternator.














Place your new JBR Passenger Motor Mount in place and tighten to the proper torque: 60ft/lbs.








Next install the two 17mm bolts but do not torque them down yet. Ensure there is approximately a 3/16” gap between the chassis and the back of the motor mount. A flat head screw driver may be used to move the mount in to place while tightening. Never attempt to loosen the bushing bolt, doing so will void the warranty on the mount.
Torque the 17mm bolts down to the proper torque: 70ft/lbs.











Reinstall the coolant and power steering reservoirs and you are all done!

For anyone that has been interested in upgrading their passenger side motor mount, this install was very easy and the results are amazing. I highly suggest this upgrade from JBR, his mounts are top quality. The 80A that we went with does transfer a bit of noise and vibration into the cabin which is to be expected but with any aftermarket part you always have to sacrifice some comfort to get the performance. Engine pitch is reduced significantly resulting in much easier shifting and greatly increased throttle response.

Thanks,

This is pretty damn awesome. All your reviews and how to's are spot on

[someguy]

A couple notes from my experience:
- Some cars do not have a ground strap that needs to be relocated. If that's the case, becomes much simpler.
- Supporting the engine, throw a block of wood or hockey puck in the top of the jack so as to not deform your oil pan (helps spread out the weight from those nasty "teeth"). You can also get away with not removing the splash panel if you're lazy on some cars, it has enough flex that it can be moved (by hand even) to touch the oil pan...hence just another piece of plastic between the jack/oil pan.
- The coolant tank is a PITA sometimes, takes a good bit of pulling to get it to come even with the tabs pushed back.
- If the studs come out on the engine side (happens from time to time), have an E-Torx socket ready to put them back in.



But as usual, great install guide. The PMM and TMM mounts are not that hard to do on these cars.

Great information, thank you very much for adding this to the thread for everyone

I have fitted both and the instruction are so clear and i am a novice

The more I look at the mounts and this how-to, the more I want to install a set myself.

Do it...PMM takes about 15-20 minutes. TMM takes about an 30-45 minutes (removing battery and ECU takes extra time). RMM takes about 20-30 minutes (jacking up the car).

Like someguy said super easy and well worth it. The car is so much more fun to drive with the drivetrain throttle response increase as a result.

I just completed all 3 motor mounts by myself from start to end in total 2 1/2 hours following the how to very easy thanks

Well, I have the RMM on and that made a world of difference. Now I just need to budget out some more money and get on and buy some of these things. The installs are easy, I'm sure of it....thanks for sharing.

Definitely save what you can to at least do the passenger side mount and then if you are still wanting to make it even more solid then I would say do the transmission mount after.

Hey MSF! I am a new member and this is my very first post/comment. Can you be more specific about the 3/16” gap between mount and chassis? Is it best to use some gauge measuring tool? I see you just used a flat head screwdriver. Please explain. I just ordered the 80 duro Trilogy set and cant wait to have them installed!

[AshFromCan]

Definitely using this guide when I get this and a TMM in a month or two. Great write up.
