The Tesla 2nd generation iBooster reservoir is mounted at an angle from the factory since the Tesla firewall is at an angle. When installing this only a verticle firewall application, the reservoir tilts towards the front and does not allow sufficient fluid to move into the iBooster. This bracket levels out the reservoir on the iBooster when installing it in a verticle firewall application. The perfect addition to your EV conversion. This is a direct fit part that levels the factory reservoir when installing onto a vertical firewall, just like how it's mounted from the Factory on a Tesla. Made with a billet construction and includes all necessary o-ring seals and factory style roll-pin for installation.
