The BM Project:

Complete Chromoly Cage

 This cage was designed by me to be light and rigid.  It ties the front
and rear suspensions in to the cage while reinforcing the roof, body
and sills.

If interested, ask us to build one for you.  Cost is $2300 installed.
That assumes the car is delivered with interior and engine removed.


Removable front cross brace allows for easy fuel cell removal.
Note bumper reinforcement plates in nose.

Note the cage is tied to the windsheild pillars, as well as three additional spots around
the door frame.

This model has the tight profile door braces.  The cage can also be made with
IMSA style protruding door bars or with a removable X brace.

The photo was taken before the addition of the stiffening reinforcement at
the "X".  See RSR cage shots. for details.

Jungle-Gym.  Check out the shock tower reinforcements.

 All attachment points welded to load distributing steel plates on the sills, not
the floor.
