Full rollcage

A couple of YouTube clips (here and here) made start thinking about getting a full roll-cage for my car.

When a found one second hand in UK I went for it. DHL shipped it to me and even if the freight was not cheap it was not as much money as one could expect.

The forward frame bosses was easy to find through the side skin using a magnet. I drilled with a small drill and then enlarged the hole with a dremel tool.

I put protective cardboard on the fenders and scuttle sides and test mounted the cage and realized that the cage fouled the FIA battery master switch.

I filled the hole with chemical metal. I think that with some padding and paint will make it look ok, but I leave that for now. I've made a new hole 5 cm to the right of the old one.

A couple of the cage bolt holes was a little bit off, so they had to be enlarged a mm to fit with the chassis.

The hood sticks didn't fit with the cage, so they had to be removed.

The standard half door doesn't fit. Maybe they can be modified and stuck between the cage and car? Lets see about that.

Rollcage 20kg

A bit heavier, but the chassis is probably much stiffer with the cage mounted.

I need some cage padding, some paint for the old battery master switch hole, and half doors that fit. The trunk cover is also a bit loose now without the hood sticks.

All of these changes can be reverted (except for the new hole), but it's not something you do every day. It feels like my car is more of a race car now than a road car. I suppose had to decide what path to take some day, and this is probably it. I also don't know what the yearly MOT will say about the cage.
