i think cages are sick and the car would be SOOO much safer with them…if anything i would think the cop would agree with the safety issue , but hey , there deff are some not so nice cops around there…personally , i’d get it check by local laws and see what they say and if there isn’t a specific law prohibiting them…then SLAP 'ER IN!

Where are you driving your car that you are worried about a roll over?

Have you ever seen a car drag racing blow out a rear tire? When they hit the wall they flip over nicely…

You didnt read ANY of this topic did you? Street cars ARE NOT safer with a cage, period.

Yep. They provide all sorts of unyielding surfaces to hit. You’d be surprised how much a body moves around in a crash with a stock seat and 3-point restraints. Now, a cage with a race seat, helmet, and 5-point harness is something else. But a cage in a street car DETRACTS, not adds, from safety. I have a 6-point roll bar in the Camaro. It’s a 'vert, so I wanted the rollover protection and needed it for the track but I realize that my the bar>my head. However, the halo is the real problem, not the hoop. That’s why a 10+point cage is such an issue. You are much more likely to hit your head on it than a simple roll hoop (4, 5, or 6 point).
Exactly, thanks for summing it up nicely rskrause.
damn out here in washington they are crazy about saftey equiptment. i am getting one as soon as i am back in the states i wish i didnt have to do it. basically what i am saying is if you can get away without it than do it but if your local track is strick like mine give in now instead of being dissapointed when you get kicked out everytime
FormulaLS1…1991 GT? Can you elaborate on the car please? I’m going to assume it’s a 'stang. Maybe some other owners of your particular car can chime in with their rollbar/cage experiences.

No
Its kinda funny that people always assume that 3 point seatbelts are unsafe or less safe than a 4 point. They are specifically designed to allow a human being to deflect toward the middle of the car in an accident. The thought is bumping heads with a human is less likely to hurt you that bumping into anything else. Real race cars have less room for a human to move around so they use multiple point belts to better keep the person constrained in the vehicle during a bad crash. Distance and time for an force applied to the body allows for more energy dissapation. Street cars take advantage of this fact where race cars cant. Since street cars(all cars for that matter) have real shitty side impact structures. A four to six point harness will only keep you closer to the impact than letting your body get away from it. Watch crash dummy footage sometime and youll see what I am talking about. As far as cages are concerned the added side impact will defintely help in a street crash if there isnt bars by your head. In a frontal crash the bar that goes near the top of the windshield actually reduces the amount of area your head has to go which is bad especially if you use a 4 point harness that keeps you inline with that bar instead of letting you deflect toward the middle of the car and downward toward the ash tray. Food for thought.
Addendum:

read the post by james waltman. pretty much describes the situation. They got real anal about this in FSAE so we all have to go through a bunch of stuff to get crash approved.
Your best bet really is to back half the car to keep the roof from caving in on your head if it isnt subie strong already. Other than that fill your car with as much honeycomb as possible. You would be suprised what a 2" think layer of high psi stuff inside you door would do. Most modern saloon race cars do this as a light means of provided better proetection in side impact structures since their windows dont go up and down. they can stuff about 6 inches which is sweet. This is also what makes irl,cart,f1 cars so safe. In side impacts the carbon skins of the monocoque provide almost no strength to the side impact. They just have a sick amount of high psi honeycomb between the skins to absorb impact. Skins just prevent physical penetration of objects. Then again their allowable peak g is around 100g’s where fsae keeps in down to 20.
It is not a big decision for you. Your car is 150mph trap capable. You need a 10 point cage and a parachute. (and a decent 60’, but thats another story :lol:)
Just one thing that I’m thinking with relations to the Halo and your head impacting… isn’t there a NHRA rule about helmet and Roll-bar proximity when the driver is fully strapped in?
Thus if there is X.XX amount of distance required with a helmet, and removing the helmet adds another X.XX; the rotation of your head in an accident should in theory clear the bars…
This not including all the other factors at work here.
I’m just thinking the same thing, because when I put my car back together this next winter I have a feeling I may need a full cage but I still want it a “street” car…
Simply put, for those of you who haven’t gotten the mesage, a full cage is not a good thing on a street car. Unless you are a shrimp, besides the safety aspect, the intrusion of the bars will severely compromise utility and comfort. They take up a lot of room, especially if it’s not a custom cage that really hugs the interior of your car. A custom cage is very expensive, BTW.
If you want to run your car on a 1/4m. track at less than 10.00 seconds, there should be no question - you need a cage or you are being irresponsible. If you get yourself killed, your greedy heirs will sue the track based on your stupidity. It will then close, depriving the owner of his livelihood and depriving the rest of us with a venue to race.

i was cutting 1.80’s on BALD tires/loose tq arm/M6/no boost. i would say that isnt too bad 
you ever try launching a turbo car with a manual and no 2-step? 
was only what, ~.17 seconds behind ur slick/skinny/auto/pro tq arm/pro anti sway combo? hehehe. just messin. but with ur new found goodness, i’d expect some 1.4s outa you this year :tup:
look for some 1.6’s this year though ill be happy with that :tup:
anyways… i wouldnt have a problem with a 4 pt, but have been tring to decide on the sidebars… i dunno

:violin2: 2 tenths is alot on a launch, and I didnt have a turbo :lol: You can do better than 1.6s, I was only stuck on them because of my converter and absence of n20 that day. If you would tie that car together with a cage and the rest of the suspension/tire you need, you could run the 9s you should be seeing. And I wanna see it!
A 6 point is a no brainer. What good does a 4 point do you turbo? It isnt IHRA or NHRA legal, it doesnt provide much roll over support, and gives you zero side protection. Get swingouts if you absolutely cant climb over the bar, but get atleast a 6 (make it an 8, no one is sitting in your back seat anyway). Drive it like a street car, build it like a race car.

you know i was only messin with ya
anyways… ive seen some 6pts with REALLY REALLY low sidebars… id consider that. id really have to sit in a car with one to really make the decision. i can’t decide through pictures. your right on the 8pt. idk. as of right now…i reallllllly dont have the time to put one in. ive got so much to do.
as far as 60fts… i already got the better tq arm…i plan on gettin the 1" rear sway (not the pro bar, i talked to a spohn guy and he said the solid linked one is not for me)… non bald tires…and another little box of :snky: to help me off the line, so i can leave in boooooost i think i will have problem solved this year, while retaining FULL street likeness
BUt the low door-bars are not NHRA legal… if I remember correctly they must fall within 6" below the drivers shoulder. Someone can post the real rule I’m sure.

Why not?
Anyone on here who knows me knows what cars I have right now…hell even TurboLS1 knows.
I’m gonna got 10pt in the Camaro this year. No use getting booted from the track after all the work to get you there. But the Camaro is not really going to be much of a street car, and definitely not a DD. How fast do you need to be that they will require a chute? I really don’t want to do that.
