Now in beta on iOS
Document your build and get followed. Trade parts that actually fit your garage. Hang out with your scene — clubs, forums, meets — without juggling Instagram, Facebook groups, WhatsApp, and Craigslist.
Four pillars
Every feature exists because builders are currently juggling 6 apps to get this done. Spec puts it in one place.
BUILD LOG
Every post is timestamped, tagged to a vehicle, and threaded into a public build log. People follow your build like a show — and you get a real record of what you did, not a lost Instagram story. Every build, profile, listing, and event has a real shareable link that opens in the app.
MARKETPLACE
Every listing is tagged to a specific make, model, and year range. Your garage auto-matches you to parts that fit — parted from other people's real builds, with full history and a seller SpecScore so you know who you're dealing with.
SCENE
JDM, Euro, Domestic, Track, Stance, Drift — clubs by culture with built-in threaded forums. Tagged GUIDE, TUTORIAL, QUESTION, BUY/SELL. Answers stay searchable, not lost in WhatsApp.
KNOWLEDGE
Tutorials are a first-class post type. Helpful replies earn you a SpecScore. The upvoted answers rise. Your weekend-saving fix isn't buried under 400 comments in a Facebook group.
SpecScore
Every builder has a SpecScore — a number earned from what they've actually done. Buying a turbo off Craigslist, you know nothing about the seller. On Spec, you see their builds, their helpful answers, their transaction history, and how long they've been in the scene.
It's reputation you earn, not followers you buy.
Why Spec
Car people currently juggle Instagram, Facebook groups, WhatsApp, Craigslist, old forums, and Discord — each doing one piece badly. Spec does all of it, together, with fitment that actually works.
