This Volvo S80 was one of three fitted with cages for a special project. The cars were essentially still in standard spec. and the roll cages had to be removable once the project was finished.
Only a back half cage was required but it had to be installed with minimum disruption of the interior trim, hence the sheet of aluminium protecting the leather upholstery. Volvo S80 roll cage.
Cage mounts were all bolt-in and had to be in such positions that the mounts would be covered by standard trim when the cages were removed. Volvo S80 roll cage.
Not quite classic yet but a VW Jetta is quite unusual. This car is intended for fast road and track day use, hence the door bars and rear diagonal brace are removable.Note the plates joining the cage to the windscreen pillar. There are also plates joining the door shuts to the main loop.

A real problem to tie the cage into the front strut tower. It's so close to the bulkhead that it's impossible to weld all round the tube. Subaru roll cage.
So the tube passed right through the strut tower, got welded to it then this reinforcing plate welded to the bodywork on top and plug welded to the end of tube. Subaru roll cage.
It sometimes a problem to restore the dash after the cage has been fitted. In this case we've modified the OEM dash tube and attached it to the cage ... Subaru roll cage.
