B MAX 2 front brace .
 

Been getting a B MAX 2 and noticed the front brace does not screw on to the bulkhead , it moves from side to side with the wish bones.

Any one drilled and taped this for a secure fix ? .

There is no need to secure that part. The play is in the wishbone pins and the bulkhead.
securing the brace won't take out that play.

Don't worry about it. There are 5 versions of the Bmax2 out now. all have this front brace. No version had any issue's.

The front bumper holds it in place. doing what you suggest would weaken the bulkhead.
