Looking at this multi point bolt in cage, any thoughts? The car is slowly being turned into a track day/hill climb motor.

My first thought when I got up the diagram, was, "A couple of brackets to hold the engine, and you won't need the body shell"

 

That's a space-frame !

I was looking at buying the exact same cage. Still not decided what I want yet. :/ Definitely a good cage though.

If you are competing then a good cage is a good idea.  Unfortunately these things do weigh a bit.  A slightly less complex cage may offer similar protection with a bit of a weight reduction.  I use a 'full' cage but without the side bars and front subframe mounts.  I compete in hillclimbs and sprints.  One thing to bear in mind is that a complex cage is often designed to protect against side intrusion from another car.

 

It will also make getting in and out when you have a decent bucket seat a bit difficult, especially as you get older!

 

Having said that, if you are happy with it then go for it.

What cage have you fitted ace? I like the idea of front sub mounts for frontal impact so the engine doesn't give me a lap dance, but it is ultimately only being a sprint and hill climb car

One thing to bear in mind is that in an accident you need to try and absorb some of the impact to reduce the stress on the driver.  A full cage like this will make the car so solid that the forces transmitted will be massive in a big shunt.

 

With a car like the mini its a difficult balancing act between making it strong enough and making it too strong and it of course depends on what type of accident it is and where the impact is.

I think mine is Safety Devices.  It was fitted by the previous owner to a shell I bought.  It is a bit OTT is as much as it has the rear X bar in place of the diagonal and has been welded into the shell.  It still has the front part which gives the shell a bit of integrity in the case of a bad roll.  Oh, and it has padding anywhere near the passenger and driver seats.

First things first. Read the rules and regulations about the class you are thinking of entering.

Will that cage allow you to fulfil the rest of the class requirements?

Nothing wrong with the cage but you will not be in the road class as you will need most of the interior panels removed.

So as I always say read the rule. Read the rules and understand the rules, not forgetting your local event rules.

Does this cage and the SafetyDevices mount into the pocket area under the windows?  -Or inboard from there, directly to the floor?

My '73 Mk3 has a little panel in the bottom of the pocket/bin, that seems to sit above the outer rocker, creating a gap

of almost an inch between the two.  Mounting a cage into that pocket seems like something would give as I tighten everything down.

I don't know if that panel is factory or an afterthought my a previous owner?

Thanks Nick---Do all shells have that extra panel in the bottom of the bin?  It's not flat, like it was meant to even the bin floor.  It's

actually angled like the outer sill, but raised above it.  It's going to make accurate drilling a real bear.

nope single skin. the cage mounting plate is angled to suit attaching to the angled part of the floor/sill in the pocket. even the old Alley ones were like that. as if they cam into the floor area they would not do much and get in the way of the seats.

 

i wonder if you have had oversills fitted.

Marvelous.  I was really hoping you wouldn't say that.   Looks like I have some "destructive creativity" ahead.  Might have to lose 

the bins completely to work in there..   --And of course this is after paint & re-assembly.

I'll get up close and personal tonight to see if they're oversills, or a scab piece just in the bin.
