Q: Are these doors street legal, or track only?

They are racing parts intended for off-road use only, meant to be run with proper racing safety equipment and a roll cage. They are aimed at Model 3 race cars and dedicated track-day builds, not daily street driving. If you are building a car for competition, these fit that purpose, and a Tesla-focused event like TeslaCorsa is exactly where such a build belongs. For a street car, our carbon exterior and aero parts are the right route instead.
