Hi, I’m Arek.

I write down what I’m learning.

Most of it starts with a car, a tool, a computer or a question that turns into a much bigger project than planned. This is where I keep the useful parts: what I tried, what went wrong, what the data showed and what I am doing next.

GT86 Console Trim Replacements

Reverse-engineering cracked OEM parts into printable replacements that actually fit inside the GT86 cabin.

The two regulars

Toyobaru and Mango

Arek’s Toyota GT86

Toyobaru

The car, the track days and everything I learn between them.

Maintenance, preparation, telemetry, mistakes and changes made after real use.

Mango, the corgi behind Flappedear

Mango

The corgi whose floppy ear gave this place its name.

He was here before the car, the blog and the idea that any of this needed a brand.

About

I work in IT and cybersecurity. Outside work I drive, build and overthink things.

Flappedear is the place where those rabbit holes become notes that may be useful again later.
