I really, really hope you've done more to those mounts than that.  :sick:

They need to be seam-welded around the edge and (as per DOA) have the sides filled in.

Mounts should be looking rather more like this:



Not like some hideous gobbed in off-cut.  :huh:

Cut the excess thread off.  I would expect you to have captive nuts in there.  If you don't then you should have nylock nuts with a small quantity of thread out the other side.  Don't cut the thread with a grinder with the nylock on though, as the heat will melt the nylon out of the nut. losing the locking function.  :wink:

measure the length fg bolt you need, cut to length and time ends,  then install them into car NUT up with nylocks

makes it easyer to release the cage should you ever have to and also bolt heads don't poke down as much as nuts

if you were been posh you would have built cage mounts up and had the nuts in the mouting point rather than under the car
all the VW's have gone bar 1.

i just used m8 bolts with nylon nuts on the bottom and some washers so the bolt dont pull th enut through the floor as its pretty thin , mines never come loose . no point in tackwelding them as it would only make life harder when it comes to undoing them :) ,

This attitude scares the sh*t out of me.

a cage should have proper feet/mounts not just be standing on the floor.  If you have a big one instead of protecting you it'll likely punch through the floor and collapse.

You should have plates on the underside of the car where the bolts go through, it spreads the stresses loads

why don't you forget about the bolts and weld the cage in?

I have never understood bolt in cages, do you remove them to do the school run or something? If a car is getting caged its usually because its a focused track car and isn't used for things that need a removable cage
