GARAGE
ACADEMY

Built, Not Bought/Learn. Build. Share.

Garage Academy is Adapt's sister brand for hands-on learning — step-by-step course dossiers written from real shop and trackside work, so you can do the job yourself and do it right.

Every course is a numbered dossier — GA-001, GA-002 and on — with the difficulty, time, prerequisites, and tools stated before you start, and a badge when you finish.

Do it right the first time

Procedures written from real builds — including what went wrong and how it got fixed.

Know before you start

Difficulty, time, prerequisites, and tool list up front — no surprises halfway through a job.

Paired with your kit

Service dossiers line up with Adapt chassis pages, so the parts and the procedure come from the same spec.

Earn it, log it

Completion badges sit in your garage profile, right next to the service history they taught you to build.
