Default BMW E46 Rocker Box Kit for Roll Cage

$300/kit

I am partnered with a local Metal Fab shop and have reproduced the Rocker
Box Kit for Roll cage set-up. I had 2 sets made to check the quality, fit and finish. These pics are on my e46 M3 destined for track duty.
Kit includes;
-Forwarding mounting firewall plate
-A pillar plate, tubing landing plate and cap
-B Pillar floor/corner plates; 2 each side
-Rear shock tower floor and curved tower plates
-steering column mounting bracket; if you delete your stock cross bar and use a roll cage tube instead.

I would like to run batches of (5), but I have one for sale right now.

I will list this in parts for sale as well, but this seems to be more specific for this track forum.

*This is my first attempt at a shared Gmail shared link folder as pics not uploading in thread tool; forgive me if it fails.

Thanks

I labeled it in the wrong folder; it is an E46 kit. I will fix link later. I have a Z4 m coupe as well.

Maybe I missed it but do you have pics of the steering column mounting bracket?

Yes,
They are the only pieces with 2 90 degree bends. The two side will have 1.5" tube relief. There are extra holes to allow for additional adjustment after a finish weld. I will get a close-up and attach to this thread.

I have mocked my whole cage now. My next phase is to mount the seat with my wife sitting in it. I am dropping the cross bar at least an inch, center the wheel and finish weld.

The back half cage tipped forward and pulled out easier than I thought; made welding way easier. Still "shit" job in places that I cleaned-up and improved.
