Tuning Parts.
Affinis Motor Sports is a Houston performance house born from JDM tuner culture — magazine-featured builds, an Attack series sponsorship, and a curated wall of the rarest Japanese tuning brands. Parts and sourcing by private consultation only.
Top-Shelf Only
Rare parts for the builds that actually matter.
Carbon · Titanium · Billet
Lightweight, precise, beautifully made.
Built, Not Just Sold
Technicians who’ve turned the wrenches.
Super-Sick & Rare
The hard-to-find stuff for serious builds.
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.
Do not settle for less. Affinis — you can put your trust in us.
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.

Forged inside Mayday Garage
HoustonAffinis came up inside Mayday Garage — the collective behind some of the wildest JDM builds in Houston, the kind that actually got driven hard, not trailer-queened.
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.

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 shop runs quiet now; the mission doesn’t.
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.
The story continues on Instagram.
Parts move by private consultation; the builds, the photos, and the culture keep rolling. Everything new lands there first.
