Introduction
What's the point of this guide?
The idea behind this guide surfaced as I was researching upgrades for my own car. I learned a lot of really useful information, but it didn't come easy. Lots of time was spent scouring old forum posts, bookmarking reddit threads and jotting down part numbers and various measurements to make sure my build would all come together without any major issues.
After all was said and done, I wanted to gather my findings and share them with others, in an easy and intuative manner — and that's why this guide exists.

This guide would not have been possible without you, the Mazdaspeed community. The knowledge herein comes from everyone's collective experience and is by no means a representation of my own knowledge of the platform.
A note on 'steps'
I will not be disclosing any power figures throughout this guide. The 'steps' are purely for organizational purposes and are not akin to what's commonly known as 'stages'.
