Anyone race w/ a cage or atleast 4 point bars, thinking about it, but can't decide, any input? Oh,and this car will be autoxing mainly, not just a little wannabe racer, it will be a trackrat...

e9nine makes a good point about the safety of a roll bar or cage in a car where you don't have a proper racing seat or helmet.

The best solution I have found is the harness bar idea. I don't know who else makes these, but you can see it in the pics in TIATO's member profile. I think I will eventually get something like this when I get around to getting a harness.

I don't know how practical it is, but I think it can be unbolted in the "off season" to retain use of the backseat again. I had something similar in my 944S2, and I just left it in all the time.

i know its off topic but what about a 4 point harness W/ out a roll cage? is it safe? JW.

I hate to be the new guy on the block preaching in my first post, so I'd like to just point out that harnesses in a car without a rollbar would be very, very bad in a rollover. Being strapped upright to the seat as the roof collapses, and your head becomes the next object to strike the road surface-the picture is rather frightening, isn't it? At least with a 3-point belt you can "fold" your body towards the centerline of the car.

There is a pic floating around the internet of an e36 that rolled and was crushed down the door rails-both people in the car survived, by virtue of the 3-points allowing them to "fold" at the waist.

I'd totally agree, I've also seen a video of a porsche racing w/ no cage but had harnesses and almost catches his head. Especially w/ racing upright seats in particular. No one has mentioned them, but just a tidbit, not a good idea. I'm leaning towards in my car since it will be a custom cage and I'll just route them away from the head area or where it would be in an accident(to the most of my ability) and then keep it that way. no one ever is in the back so it's not a big deal to not be able to take people in the back of my car.

ya ive heard this to, i heard you should have a cage if you want 4 points but then again you cant have a cage W/ out a helmet.....and so on. but wouldnt it be much sefer in a collision that didnt result in a rollover to have 4 points? i geuss its a gamble.

I've got 4 points in my other car, not that big of a deal. I couldn't picture them being any more unsafe than just regular seatbelts. I think they would provide more stability in a crash but I could understand how they would get dangerous in a rollover, but I'd personally take the chance...

So you want a cage and going to go racing with it? Then you will have to have at least a 6 point... it can be bolted or welded in, though many agree that you should have a weld in cage. You can buy a bolt in cage and just weld it (which will help keep cost down)

I would not run harnesses on the street...

he also said it would mainly be an auto-x car. A roll bar/cage is only added weight in auto-x.

Basically unless you go full bore, helmet, harness, and bar/cage, do not do it. You really need the whole package or nothing.

I thought about doing similar, but then I started hearing a lot lately of busted open heads on cages. Not cool.

nickmpower · « **Reply #25 on:** July 22, 2006, 09:49:59 PM »

as long as you are straped in with anything other than a 3 point, your head should be fine. Also i would rather have a bump on the head than a break in the neck

I run both the harnesses and the stock 3 point

i have them bolted to the rear seatbelt points which creates a ~50 degree angle with the seatback so spine compression is a minimal concern, moreover when im not PITL'ing it, i use the 3 point and this still alows me to 'fold' over in the event of a roll over. Mind you, I don't have a rear seat and actually rarely have even a passenger seat cause im so lonely (:

I'm thinking of putting a roll bar in the car with race seats and harness, but not a full roll cage. Would a roll bar not do much good? I'm not driving this car around, it's just a trackcar /autox.

But for now I'd be interested in a replacement of the worn 3 point seatbelts (WTB).

How are you guys able to run harness without racing seats? Do the shoulder straps just rest over the seat? Or do you have them going through the headrest? I cant quite picture this becoming a suitable or safe solution.

being short is a win i guess? I don't see how my head would ever contact a 4 pt. unless i lifted out of my seat and rolled my head backwards...

the only car i was in that had 4 pt. without a cage ran them across the seat backs, outside the headrest. didn't feel very safe...
