Houston, TX · Japanese performance
Bespoke performance tuning parts.
A Houston performance house born from JDM tuner culture: magazine-featured builds, an Attack series sponsorship, and a wall of the rarest Japanese tuning brands. Parts and sourcing by private consultation only.
We don’t sell on price. We sell on trust and desire.
Affinis caters to enthusiasts who don’t shop by the dollar. They shop by trust, taste, and the desire to build something exceptional. Car culture was never just the machines; it was the late nights, the first pull of a big turbo, learning to read every clunk and hiss like a second language. We provide only the rarest, most bespoke parts to the people who truly share that, by private consultation, one build at a time.
What started as a Houston build bay turned into a hunt for the super-sick stuff: carbon aero, billet, titanium, lightweight hardware for the top-shelf builds that actually matter.
The full history
Built to be driven, never trailer-queened.
Forged inside Mayday Garage.
Affinis came up inside Mayday Garage, the Houston collective that pioneered the city’s car-meet culture and turned out some of the wildest JDM builds in town, the kind that actually got driven hard.
Six years on the tools before the first sale.
Every part we recommend, we’ve fitted. Six years as a performance automotive technician in Houston’s exotic and tuner shops (GT-Rs, Gallardos, Bentleys, Vipers) is where the standard comes from.

All of them
Affinis was never the finish line. It’s where the instinct started.
The golden era of tuning is fading: grassroots meets, hard-won knowledge, the raw connection between a person and a machine. This archive exists to make sure that spirit doesn’t disappear quietly. Build, drive, preserve.
The Lost Generation.
A film and a living archive preserving the golden era of car culture (the people, the builds, the stories) before they fade for good. Affinis is chapter one of Machine & Memory ↗. Be the first to know when it drops.
