Bolt in roll cage? fc3s?
 
Hey guys I really want a bolt in rollcage for my fc it is going to be primarily a racecar. but it needs to be road legal and will be driven to the track.

Are roll cages illegal? and im wondering where i can get a pre made bolt in one.
thanks

you are better off with the custom cage if you plan to drive this car on the street. attention will have to be paid to make sure the cage is out of your way. all the bolt in cages I have seen have not left much room for the driver. the head room is seriously impaired. if you are short and thin it may work but if you are over 5"8" tall you will want the headroom. the cage can be very deadly in a minor road accident if you are not wearing a helmet.

Rollcage + street driven car = bad
Rollcage + track only car = good

I had an autopower bolt in cage in one of my RXs. I'm 5'9 and it did not really take up much of my headroom, even with padding. As far as it being dangerous on the street, :bsflag: . A Properly padded cage in a minor accident is no more dangerous than not having one at all. Ask me how I know? As small as the cockpit is in RX-7's, if you were to hit your head on the cage, you were going to hit your head somewhere else just as hard if the cage was not there. Given, a custom fit cage would be better. Either of them should be padded on or off the street/track.
Imagine this scenario, an SUV or any car for that matter t-bones you on the street. Do you think you'd be better off with or without those bars encircling the door. Cockpit penetration is the worst thing to happen in an accident. Check out my brothers 1st gen. He and girlfriend died, girlfriend was in passanger seat. Look closely. I'm not going to say that a cage would have saved them, but his girlfriend might not have been liquified.

HOLY SHIT!! That little pile of stuff is a 1st gen!! That's scary as hell. Sorry about your bro though. I'm working on selling my 1st gen and buying a street/track one. It has a full custom cage with lots of padding. I feel safer in the one with the cage than my current car. And alot safer with the cage after seeing that pic.

how is it not safer on the street ......." is beyond me" you'll still have to wear the stock seat belts or else you could get ticketed for not wearing them, even though you have your harness on. It's not DOT legal, then you can't wear it while driving on the street. Since the cage doesn't inhibit forward movement then you're ok.

rx-heaven,

I am sorry for your loss, but a bolt in roll cage or welded roll cage would have done little to help in that crash. roll cages are designed and built to keep the roof from collapsing in the event of a roll over. there is little advantage in side or front/rear impact. yes door bars help to prevent intrusions but these are not going to prevent serious injuries in a t-bone type wreck. I have crashed my own car badly and the cage was not damaged but it did nothing to minimize damage. I have been around racing for a long time and have seen many bad wrecks with all types of cages, and they work well for what they are designed for, roll over protection. In my own wreck at over 100 mph I did not hit my head on any part of the cage or car. my cage was built with added headroom to prevent injuries from and accident. my statement about pre made bolt in cages is they have to leave extra clearance so the cage can be installed. this brings the cage closer to the driver and passenger. I have seen several bolt in cages for the FC and all have limited headroom, so if your taller than average or want the security of knowing you are clear of all tubing have the custom cage built.

I really wanted a roll cage for looks mainly but after being enlightened on the pros and cons I'll reconsider a bolt in. I'm 6'2" so I need all the room I can get. I almost doubt I'd get under the roof with a helmet with such a long torso.

are you aware that you just opened a thread from 7 1/2 years ago?

HAHAHA that's funny but hey very good info. I'm still considering mine. I might just do a rear half.
