The Protuner BMW E90/E92 Hydraulic handbrake seat base allows for the quick and easy installation of both a side mount bucket seat and a hydraulic handbrake to your vehicle.
No cutting of the interior.
No welding on brackets for the hydraulic handbrake installation.
Simply remove your standard seat, install the Protuner seat base, bolt in your choice of side mount seat and plumb in your hydraulic lines to the handbrake.
