thank you very much! that is a great idea, i will probably do something similar. looks like i may have to drill one more hole.
i wanted the cms cage, but i ended up with the ap clubsport cage, it connects to the top of the rear seats the same way the cms does, but without that bend |

My car is headed up to the CMS shop in Des Moines next month. CMS is planning to use it for templates for a redesigned bolt-in half cage, more similar to their Camaro and Mustang offerings. They are also installing some Cobra Nagaro seats that are inbound from the UK (blue stitching).
Will provide updates as work progresses next month. |

What size hardware M8 or M10 and what shape of weld in nut? Some of them have different kinds of flanges. I am in the planing stages of a custom roll bar and like that as a mounting for the main hoop.
Also what is the thickness of the mounting plates of your cage? Quote:

I'm working with a builder in the UK for mine. They're working out some stuff to get a US distribution hub setup.
Should have more info in the coming months. |

How are the fronts mounted on this? Existing holes or did you have drill new ones? Have to weld anything?

The back doesn't line up to much that's why we welded in plates and welded weld nuts to the plates. Like I've been ranting. You can't have a safe cage without going balls deep. It's either safe, partially welded in or it's for show. I don't feel there's an in between. My cage is one off from a shop in NorCal. |

A fully welded in cage if done correctly & welded to all pillars etc is stronger (much more important is the cage design) the big benefit of a 'weld in' over a 'bolt in' is structural rigidity which in turn improves a vehicles performance. A correctly designed & installed 'bolt in' cage is extremely safe (I've had several in my race/rally cars & can speak from experience). Yes if you buy a poorly engineered cage from some amateur it's unsafe but that applies to any cage be it 'weld in' or 'bolt in' & it won't be allowed through scrutineering at any half decent competitive event anyway. Highest quality M2 cages & options... https://www.agi-precision.com.au/pro...in/bmw/bmw-m2/ If you want the facts take a look here... https://www.agi-precision.com.au/whi...-best-for-you/ These are as good a cage as you will buy anywhere, are approved for use in national levels & are used in both 'bolt in' & 'weld in' forms in the majority of tarmac rally competition cars I compete with (which is potentialy one of the most dangerous & highly scrutinized forms of Motorsport you will find anywhere).

For those that have kept (or plan to keep) their rear seats installed with a half cage - I am curious why? I cannot think of any reasons to keep them but do see it done pretty regularly. I'm definitely not trying to be a smart ass - I'm really curious why keep the seats when it seems like there is much more positive in removing them.
Benefits to removing the rear seat - negate the weight gain, do not have to mod the seat assembly (better if want to sell or reinstall), a close out kit can be a much cleaner look, more versatility with the space, etc. Can't really think of any benefit to keeping the rear seat in place unless maybe you have no where to store it or prefer the aesthetics with it in?

Which is why my 275R & other cars with factory fitted cages such as GT3 & CSL etc have no rear seat from the factory & are classed as 2 seaters. There are some very stupid regulations in the US which I don't understand, but for safety reasons alone you obviously should be removing the rear seat if your fitting a half cage as you don't want anyone back there, plus there's the added weight savings etc.

On your very stupid regulations comment - eh, we have plenty & do not need the government stepping even further into anything else.

I'm very well aware of what a safely built cage is. My shop neighbor/ friend is Kibbetech off-road. Check out his YouTube. I had him inspect my cage and he said it looked perfect and very structural. The only safe way to go to the floor pan is with huge plates supporting the legs. |

The cars are made from multiple layers of metal. (EXCEPT THE FLOOR PAN) lol so the areas my cage is bolted/welded to are not accessible from under the car. |

I'll just leave this here.... https://www.agi-precision.com.au/history/
I suggest you take a look & reconsider your opinions, you might even learn something. AGI builds 40 cages a month & has done for over 10 years, Adam also builds true turret to turret weld in cages (not half arsed shit) for WRC, ARC, WEC, TCA, ANDRA, WTA, TAC & anything else you care to mention. AGIs cages for the M2 (or anything else) are as good/safe if not more so than you will get anywhere. Conceited Americans .

Yes. It’s my understanding that CM will be adding M2 half cages to their line up. I’m the guinea pig.
