Oh, I misunderstood. I thought you meant 4 point harness. If you wear a harness you need a roll bar or the harness will hold you in place in a roll over and the roof will come down on your head. Harness bars are ok for autocross because the chance of a rollover is so small. The difficulty with a full roll bar and factory belts is the belts can allow a lot of travel in a crash and you could impact the bar.
On the street the safest thing is no cage and factory belts. If you have a roll bar with no A-pillar bars you can probably run 5-6 pt harnesses safely. You do run a risk of neck damage in a crash, but in other ways its safer

As many have said, get rid of this thing.

I think that's not a qualified cage.
Even if you want a roll cage in your car,
1) it should have no front roof bar or its front roof bar is away from you head so you head won't hit it in a front crash;
2) it should have heavy padding;
3) it should be built by strong yet able-to-absorb-momentum materials, such as T45.
Just my opinion.
For people suggesting that a roll bar is one way or another dangerous without wearing a helmet, I suggest that a qualified roll cage like I said above:
1) Should be safe in a rollover, which is obvious;
2) Should be safe in a front crash, because you won't hit the roll cage one way or another;
3) Should be safe in a side crash, because the padded bar makes your head nearer to the car's frame (let's take both the roll cage and stock frame and the frame), so the frame will help your head absorb most of the momentum, instead of your neck.
For the 3rd point, imagine you're sleepwalking really fast. If you hit a wall, you'll at most break your nose and start bleeding. If, however, you hit a cabinet which is exactly as high as your neck (similar to the effect of safety belts), you may break you neck, which is fatal.
Therefore, a well designed roll cage will make you safer even if you don't have your helmet on.

Long story short, the effect of a roll cage with appropriate padding should be similar to a smaller frame (the pillars are all becoming nearer to the driver), which is by no means going to put you in danger.

80% of you sound foolish. If you had stock seats that sit way high and a crapper cage that sat way low and you didn't have harnesses yes it would be very dangerous but most of us have new seats that sit much lower and I would hope you have a weld in cage that fits right and in a crash you would not hit the bar and even if so I would rather hit a bar than have the road crush my head from the tin can of mettle of an Evo roof. I myself am building a cage that's a 5 point style so it's just the back half but has many more points to it. I rolled my friends truck at literally 10 mph and the whole roof caved in and almost killed my friend. If you drive your Evo on the street like the rest of us.. Keep the cage or get a weld in cage that doesn't go to the front of the car
Brothers STI after a 1000' roll down the side of a mountain. No roll bar/cage. He walked away without any injury. Wear a standard seat belt, and keep all safety equipment on a street car. I would stay away from a roll bar/cage on a street car.
I like the bolt in option so at the track you can put it in, and take it out for daily duty.
