I know this is non compliant but after a recent trip to the gravel I am taking safety a bit more seriously. It is a given that the MSA think such a cage does not provide sufficient safety but does it provide some roll over protection or are you better off without it. I want to keep my car as a road car and clean inside hence half cage and bolt in.
Am I wasting my time? Does anyone have any info on damage evidence with compliant cage versus chocolate one?
There is a secondary gain from half cage which is I could move to harness and hans.

Renny is prob best placed to comment.

My 2p worth - A half cage is better than no cage, but make sure its a decent/reputable motorsport cage and not a 'show' cage (if they are still a thing).

Thanks Adam. Yes I'm hoping Denny will have comments and tech input. My initial thought is as yours--better than nothing.

I thought half cages were MSA compliant for cars under 2000cc?

There is nothing to stop you fitting a rear cage to the TT. It wouldn't be compliant for Modified as engine is >2000cc, but it may increase protection and enable fitting of a harness (if you don't already have one).

Have a look at what Safety Devices, Custom Cages, or Protection and Performance (Dan Evans) can do as a bolt in option. Happy to chat about the options.

Thanks Renny. Do the MSA have any research on why bolt in is inferior. Really anything saying what I might buy is pointless

"Bolt in" generally requires some welding of mounting plates so the name is often a misnomer!

Are there off the shelf full kits or do you not want to cut the dash?

An approved cage will have been proven by analysis, material grades, one knocked up in a shed wont, and if you want to go race the car or compete more seriously then a cage will be a pre-requisite.

The SMRC Minis run 'bolt in' cages

A bolt in cage may be easier to fit, if from a proper manufacturer, no problem with performance. Your issue will be that there may not be any cages developed for such a recent model of car. This would mean a bespoke cage being developed. In which case, I'd seriously consider using Dan Evans at Protection and Performance
