roll cages?

any roll cages out there?
Since our little group have been tracking for a while now and as a result our speeds, times and so called skills have gotten much higher and better, I believe it may be a wise move to start thinking about a roll cage. Anyone know of one that can be lived with in a street car?

Any insurance issues with a roll cage? I thought someone I knew inquired about it and his insurance said they would not insure his car if it had a roll cage.

roll bar, yes. roll cage, no. You don't want to knock your bare head into a steel roll cage bar. Roll cages do not go in street cars.

There's the Mazdaspeed one if you don't have a sunroof or mind losing the left & right vents. About $875 through Japan Parts...

Exactly. Roll cage will damage your head in a collision on the street. Even a roll bar placed too closely to the seatback can still damage your head as it's tossed back.

If you're tracking that often and decide to go with a roll cage, dedicate your car to the track and trailer it.

a piece of tube behind a recline-able seat is no bueno. i was rear ended at a dead stop by a vw going no faster than 20-25mph. i smashed my rear glass out in my single cab truck along with the top of my head hitting the top edge of the cab-glass lining (meaning my body extended up and away from my seat. yes, i did have my seat belt on).

there have also been many experience from emt/paramedics when coming upon rear-ended vehicles with the driver ending up in the back seat.

DD caged vehicle, generally not a good idea.

The SCCA requires a seat back brace, attached to the roll bar/cage, to prevent the seat from collapsing and having the driver end up in the rear of the car.

And the harness will hold you in place as well.

I have a roll bar...and I think that with the padding around the upper part of the bar...I wouldn't have a problem in a street accident. The seat will not be able to recline to the point where my head would hit the top of the bar...it would hit the harness bar first.

I was looking at this too OD. Did you see the one that Dannobre installed in his car? Here is this link: Roll Bar/Racing seat install

I was mostly looking at it because I wanted to be able to add harnesses but it's not safe to do so unless you add the roll / harness bar.

The thing I like about the one he installed is that the cross braces bolt in and out so you could remove them for the street and free up your back seat space. Not sure how easy it is to take out the whole thing though.

Just remember that your body stretches in an accident. Even with a full shoulder harness, your neck will stretch several inches w/o causing you injury. The padding available for roll bar/cages cushion the blow a little. But, this is only a little and in reality will do very little to protect your noggin (head).

Actually, that's not an accurate statement. From Section 9.4.1.B of the 2007 SCCA General Competition Rules:

Quote:
Seats homologated to, and mounted in accordance with FIA standard 8855-1999 or higher need not have the seat back attached to the roll structure.
