There are two main types of lambo doors: bolt on lambo doors and universal lambo doors. Bolt-on kits are specifically engineered for the given vehicle application, and universal kits are not. Therefore bolt-on lambo doors are generally more expensive than universal lambo doors, but they are much less difficult to install relative to universal lambo doors.
