Bespoke
Performance
Tuning Parts.
Affinis Motor Sports was 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. The storefront's retired; the instinct never left.
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 never sold on price. We sold on trust and desire.
Affinis catered to enthusiasts who didn’t shop by the dollar — they shopped by trust, taste, and the desire to build something exceptional. We provided only the most special, bespoke parts to people who truly share the passion.
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.
