Roll cage for a DD?

Thanks for the input, I think I'm convinced that a roll cage won't be needed but just thought it would be a good thing to have on such a small car excluding the fact that I can crush my skull because of not wearing a helmet.

Nah, this is what you need

Believe it or not a Sheikh in here was asking about this car and was willing to buy it at any cost.

You don't need a cage for the street. The car is about as safe as it can be on the street.

You'd get a cage for safety, if you're taking a corner on a race track at 160km/h, because the stock car isn't designed to take those types of forces that would result from a roll over at that speed.

There are some performance gains from a cage typically, as it really stiffens the car. However, this isn't an ae86 (which is comparitively a very loose car) the gt86 is a very stiff car from factory, and while it would get stiffer with a cage, you're also adding weight.

I track mine with semi slicks, and I don't feel the need for a cage. And I've had an off at 150km/h. (Semis + standing water = adjust lines/speed LOL)

I would only cage mine if I went to slicks on the track, or the type of championship I was entering it specficially required it.

A cage isn't going to protect you in a head on, if anything it prevents the car from absorbing the impact, that it would have otherwise. When you see a crumpled car after an accident, thats a GOOD thing, it shows it absorbed the energy.

Roll cages are for roll over protection. And, I would say multiple roll over protection. The local demo here was rolled on a test drive, rolled two or three times. A, B, C, pillars proved to be quite strong, and car held its shape exceptionally well.

Sell your car and go buy a Saab or Volvo.

Hell, i think you'll like this.

I thought our cars had one of the highest saftey rates with all those air bags to protect us from side impacts.

For a street car, don't get a cage.

I have a thing I usually post in threads like this...

It is usually longer but...

There are two safety systems you are talking about. 1 is for the track and expects the squishy human to be in a rigid seat with a helmet (and a HANS) and a cage. 2 is for the street and expects the squishy human to move around a bit in an accident. It has airbags and crumple zones and auto reel seat belts.

Mixing and matching these is a not a good idea. If you hit your head on a roll cage even with foam on it you will severely injure yourself. If you wear a helmet on the street you will not be able to see everything and you will hit something/somebody. And so forth and so on...

Even the safest roll cage still needs protection for the driver.

Imagine worst-case scenario:

Now imagine your head versus this crumpled space:

Keep in mind this is a properly tied-in, welded cage. If you are buying a bolt-in cage, you might as well leave your seatbelts off since it won't do jack squat for side impact protection.

Oh, and if you survive the wreck but are hurt? Good luck finding an EMT that can properly extract you out of a cage like this.

Race cars have certain designs built in to their cage/safety equipment (see: shoulder collars on racing suits), to help save a driver's life in an emergency. You have no such luxury in a street car..

Just... don't.

Its a vicious cycle, that roll cage.

Roll cage = harder structure = more force transferred to your body = you cracking your melon on said cage because normal 3 points won't hold you in securely.

To secure you from hitting said cage you'll need a harness, one that wraps around the crotch so you don't hang yourself by slipping underneath during a collision (imagine the lap belt portion as the noose.

If you secure yourself to a seat (pref. one that doesn't recline because that's a point of failure and if it fails you fly into roll cage or out of the car), the forces will transfer to your neck. This necessitates a HANS (sp?) device.

Lastly, if you have a closed helmet, the airbag will deploy with enough force, the visor may or may not shatter.

A roll cage is part of a safety system. Not to be used by itself as that would cause more harm to occupants inside the car.

Oh, the door actually has a side impact beam. It'll provide enough protection when combined with the airbags. "Enough" being survivable. Anything beyond the "rated" protection... you'll probably suffer internal injuries and whatnot.

Wow guys thanks for the responses, I didn't know it was this complicated and I'm convinced enough that a roll cage is more of an enemy rather than a friend sometimes.

Some good advice here, although I'd be tempted to pop over to a Porsche forum and ask some GT3 drivers with factory fit cages how they feel about road driving.

A GT3 does not have a roll cage configuration... it has a roll bar configuration which doesn't intrude into the drivers/passenger area being located entirely behind the seats. A roll bar is as far as you'd want to go for a street driven car if you also see track duty.

That said, have y'all not seen the impact tests for the GT86; it does pretty well stock with side impacts.... Only real danger as seen on the forums is flying off embankments and crashing into ravines...which you'd need an ejection seat with parachute to survive.

Thought I'd seen some 997 4.0s with full cages and some pre 997 gt3s too ; could be wrong.

Remember the jokes about the 4.0 having detachable sidebars for Ring TF days, lol.

Anyhows Subaru will sell you a road legal fully caged RA, notwithstanding the dangers.

Topical thread as I need to make my own decision on cage this year; car focused on track use but driven to events so am mindful of the safety considerations.
