Masata front tower bar for BMW F-series - sharpen steering feel and add serious rigidity

Transform the front end of your BMW F2x and F3x with the Masata one piece upper tower bar. This robust chassis reinforcement links the suspension top mounts to reduce flex, boost precision and deliver a tighter, more confidence inspiring turn in on fast road driving. Built from aerospace grade aluminium with a discreet black finish, it is a direct fit upgrade that uses factory mounting points and requires no cutting or drilling. Backed by the Masata Lifetime Warranty for total peace of mind.

We have fitted and run this Masata brace on our own cars at MJ Modifications, and customer feedback has been outstanding. Owners report a planted nose, less scuttle shake, cleaner feedback through the wheel and a more connected drive on B roads and motorway slip roads. Pound for pound, it is one of the smartest handling mods for BMW F-series platforms.
