My brother wants to add a half cage to his 914. Any info from anyone running one would be greatly appreciated. Pro's and con's that you may have experienced?
Weld in or bolt in.. Either way works for us but leaning towards welding it in.
TIA..

Racer Chris isn't too faŕ from you.
IIRC McMark was doing GT kits, nice one that contoured the firewall. But that was a long time ago.

If it's a part time racer street car you want to be able to use the stock seat belts, the 5 points are a PITA for every day use.

Mostly a street car but some auto-x time as well. I pm'd Mark about his cage.
Think he was planning on a 5 point harness anyways.

I vote weld in. I helped a buddy with his bolt-in GT bar and didn't like the way it forced the bar to be set forward - you give up some room.
Given that, you can't go wrong with @ChrisFoley products, assuming you don't want to fab your own.
I went a bit non-traditional with my design as I didn't want a full main hoop and did things like relocating my seatbelt retractors so I'm not sure these pics help but maybe will give some ideas. I call it "the roadster cage".

Maybe these pictures will help. Photos are not my car. I have a full cage.

One of my 914s had a Safety Devices cage. It was welded in, but they are bolt in/weld in friendly.

Street car.. Used for DE/Autocross.

Biggest gripe? Made taking the roof on and off a bit more PITA.. and more often than not, I just left the top in place

Ran both harnesses and factory belts.

No door beam supports like some of the above have. Not sure how much that actually helps in an impact.. or if they would bend in and cause more harm than good. Remind me of the "pro Street" type 1/4 miile cars with albeit rule complying but curious designs.

A half cage/ merely a rollbar hoop I also wonder how much rigidity is added to the chassis vs the additional weight.

I had some pictures on an old photobucket site.. not sure if I they are still accessible..

The other issue you will notice is that room to swing your feet in and out is cut down with a 4/6pt cage.

I think one of these half cages would be perfect. With the foam is it streetable? Or is it a headbanger

Something like the last two pics. My brother is 6'01'' so he needs the leg room.
I'm waiting to hear back from McMark.

Yes. it is streetable. Yes the foam really helps.
The only time I bang my head is when I am working on the car. Never during regular use.

I have a safety devices bolt in cage that was welded in by PO. The supports that go diagonal to the center hump (like the gt) limit race seat travel. Ok for me, but I’m short at 5’8”. I’d be concerned about leg room at 6’0”. I’ve seen versions that don’t have the center diagonal.

Also, the bar in front horizontal is set rearward from the top of windshield (assuming they did it so it wouldn’t interfere with lid latches). Being short, my seat is moved forward, which puts that horizontal bar near my head, my helmet grazes the pad. I lowered my seat by cutting out the floor cross support and it’s fine now, but not a mod I would want to make on a nice car...

Weld in cages are always preferable to bolt in from a safety stand point, and like chris said you get more room. If you cant find any prebent stuff it probably wouldn’t cost much to have a reputable shop make a half cage. especially if you strip the stuff out the way. If it hasn’t been mentioned your back pad will be sacrificed.

A full cage is out at this point. Leaning towards Mark's cage with maybe a tweek or two to it. Like this one but with some bent side supports to make it easier to get in/out. Seams like the seat would be able to go back a little farther.

Whatever you get, buy some real roll bar padding for anything near your head. Not the cheap open cell split foam tubes.

Even "just" a weld in rear hoop makes a noticeable difference.

Plan your harness mounting along with putting in your half cage. Many times they tie together or may need to not interfere with each other. Might as well plan for racing seats too, they all need to work together.

The half rollbar I have allows the driver seat to go all the way back which is important for me at 6'0". I need to upgrade my padding to the harder SFI stuff. The half rollbar itself its probably not really needed, but makes be feel better incase of a roll at track events.

I sold my roll bar a couple years back.
