In 2020 I wrote about the potential of the Subaru BRZ but its lack of a track-oriented trim level:
If we want a truely lightweight track-oriented weapon like the 2002 WRX STI Spec-C Type RA, we'll need to build it ourselves... or really, deconstruct the cars we have, in order to make one.
… so I built one myself.

It had been five years since I had owned a track car, it was the early months of the COVID-19 pandemic, I was languishing, and my wife said "You need to do something, you need to make your own happiness".
Your Own Happiness
‟Your Own Happiness” is the name I've given to a 2017 Subaru BRZ purchased in October 2020 with 66k miles. The build mission is a trackable street car with a whole bunch of very subtle OEM+ aesthetic changes.
I've given myself a few principals to guide the build:
- The Subaru BRZ / Toyota 86 is a perfectly balanced drivers car for those on a budget.
- This build will be a trackable street car, in that order.
- Power is a band-aid for poor setup and lack of driving skill.
- Nobody is impressed if you can only pass in the straights.
- Weight and simplicity are key: Complexity means more maintenance, more weight, more cost, more heat, and more futzing at the track: reducing fun and seat time.
- A car that reinvigorates the idea of driving delight at an affordable price.
- Drive it to the track & back
- Make power with 93 Octane
After a six-month search for a gently used Crystal White Pearl Kouki (2017-2020) BRZ or 86, I found one on the Subaru Certified Pre-Owned web portal in Annapolis Subaru. I called them and immediately put down a deposit. I rented a car and drove 11 hours on a Friday night, starting at 10pm, arriving at 9am Saturday morning. The car was in great condition, and lucky for me, this was just before COVID-19 caused used-car prices to skyrocket.

Many, if not most of the performance improvement ideas were taken from my previous RASpec Impreza build, and applied to this car, only simpler.
Thus far the car has seen 18 track days between racing & drifting, and has handled them beautifully, with only a few minor issues. It’s not making ridiculous amounts of power for a street car, keeping reliability and affordability in check. Most importantly, it’s fulfilling its destiny as a driver’s car, customised for its intended use and used well.
The car itself, the physical object—isn't what makes me happy, its the involvement in creating my vision with my own hands, it's the participation in motorsports, and of course the people and friends I make along the way. That is my own happiness. What is yours?
