Not sure where you're based but SW motorsports have done quite a few z4 cages, probably a decent place to start.
Good luck with it, great track car imo.

If it was a Z4MC, it would be worth millions, but it's a Z4MR, so £0.50 and a conker?
the execution of that cage is fantastic!Snakobs wrote: ↑Wed Apr 12, 2023 11:37 am I have also been aiming to achieve the same thing of a cage for harness whilst retaining the stock roof and hoops. After hours of research I've stumbled across this build which removed the hoops but used their location for the cage mounting points so retains the roof.
I wonder if it is possible to fix a bar behind the seats running width ways through the cabin for harnesses to mount to without the need for a full cage. Not exactly what you want but closer, link here: https://jr-wheels.com/vehicle-gallery/1054
