MS3 recommended mods?

I'm not sure I plan to go much further due to concerns with emissions.
If I was to go further, I might consider the engine mount and short shifter.

hahahahahahahaha
 
Hey folks... I keep seeing the rear motor mount listed as one of the first and best upgrades. What is that doing for your performance? I already got the recall notice and had it checked / swapped out. I am good to go. So why should I replace it?
 
oh, by the way, I just found out that the corksport intercooler has a larger than stock mass air flow housing. I'm crossing it off of my list as we speak.
 
what brand of Rear motor mount you guys recommend? Does it make a big difference is the ride?

that was the transmission mount.

Rear mount locks up the most movement in the motor. Shifts are better, and if you do a dyno with the hood up and your watching... a rear mount may save you a heartattack looking at your motor move.
 
for the mm im using street unit 62a dont get that... i regret it im about to order the 90a insert for the su mount 62a is too soft... and ive heard good things about the trz poly mount.. it also depends on if you can deal with vibrations and what your goin to use the car for, this is my daily driver, i dont drag or autox but i still need a stiffer mount... and for the tmic im using ets 3.25 no rubbing issue that i noticed

It really depends on what you want. For me, since its new and under warranty and almost perfect the way it is; all i really plan on doing is what you see in my signature. However, you can go much, MUCH, further.

Honestly, not to sound like an ass but searching on THIS site, compared to others I've been to, can get you VERY good results. Being that this car is still "new" to the auto world, to almost everyone here as well as the vendors, questions you might be thinking about asking might have already been answered.

If you have the time, just lurking around the forums and seeing what people have to say is a great option. Heck, I know my post count is small but that doesn't mean I don't read most of the threads in the forum. Sometimes taking the initiative to read up a bit on your own can give outstanding results.

And Welcome to the forum.
Best information said so far, i am doing the same thing.
Reading and learning.

Thanks for the info Palerider.
 
hey, i'm extremely new to the board and to the mazdaspeed3... I am very curious about many things, but most of all why a motor mount is a good upgrade? Will somebody explain to me in dummy terms why upgrading the rear mount is so great?
Thank you

Real quick explanation is that the stock mount has a lot of play in it...thus the torque that is engine outputs is used to sway the motor in the engine bay instead of transferring it to the ground/wheels. The stock mount really lets the engine sway back and forth. There is a video on you-tube where a guy did a dyno pull with his hood open and it was surprising to see the engine sway so much.

Another benefit is that the mount since it plants the engine, the 3rd gear shift and all shifts crisp up. You get a more solid feel while shifting since the engine is no longer pulling on the shifter cables.

The overall difference will be felt when you smash on the accelerator, with the upgraded mount the car will accelerate instantly, while with the stocker, you have delay and a much more progressive feel.

Oh and I almost forgot...a good upgraded mount will also reduce if not eliminate wheel hop. The stock mount introduces horrible wheel hop...so bad that it can throw off the alignment...it happened to me.

Great explanation. I remember when the dealer rev'd the engine for some guy and I saw the motor move I thought, "ooohhh I trust its designed to do that!"

How is the install???
 
Yeah I threw off my alignment a couple times on the stock mount :(

The upgraded rear engine motor mounts have to be the best single mod for this car period.
 
yeah, fo sho. If bang for buck is important and/or stock like vibrations (none)...get the CS inserts.
