I guess when I wrote "slow and steady" build, I really meant it
Fast forward nearly five months and I haven't done too much to my car due to buying a house. Fortunately, it has a four car garage so I can really enjoy working on my car!
Since the last update, I've reached the 4000 mile mark and am still enjoying the BRZ more than ever.
I have also purchased and installed an HKS Hi-Spec Power L (more in next comment) as well as purchased a third (fourth?) rear brake light that I'll install soon.
