What would be the benifits of a full cage if you do not plan on racing. Just street cruising? would it be safe either way to have it? Any pics of cages Exocets?

i dont think there would be a benefit if you werent going to track it! its alot of extra money for more awkwardness on the road in my opinion. I've gone for full cage, but mine is going to be a track weapon and the cage is there for extra stability of the frame/chassis and a mild form of protection in a collision! if i was just going to road drive it, i'd go for the none cage version, especially if i lived in america where the sun shines a hell of alot more!

Extra stiffness would be nice but you make a valid point! Being 6'3", I am worried I will poke out of the top of the roll bars Hopefully I won't look ridiculous in this car!

get a cage. that weak roll bar wont do ANYTHING when you roll over.
Im getting one on mine in a month or two. But it wont be like the inadequate (in my opinion) race version. The "a pilliar" tubes will be integrated into the chassis, main hoop where the normal bar mounts, and rear down tubes to a platform welded above the shock mount to tie in correctly.
get it made somewhere, was quoted between 650-750 from a few shops
I have seen TOO many miata pictures of flipped cars, and it just isnt worth it. my life is owrth 750 bucks. I put a full cage in my miata from day one.

The roll bar has been designed to hold up in a roll. Probably not a multiple roll but that's just the way things go. A cage would be difficult to use in a road car. It's difficult to get in and out in the race car and if you've got a cage you should really have a full harness and lid otherwise if you do go over your head is going to smack those big thick tubes. Trackday/race, absolutely. Road... not so sure.

I put a full cage in my miata from day one. You say it won't do "anything in a roll" you say the cage is "inadequate". You compare it to an MX5 which is much heavier and is more likely to roll and has a narrower track width. Structural engineers designed the M bar to withstand 2.5 tons of force on the seat belt mounts. The M bar passes the UK IVA test. The cage is built from seamless tube and is approved by the MSA. It is blue book spec and is bolted in so it could be reused if the chassis gets bent.

I think what Fresh is saying, in a roll/multi roll over were alot of the force might be coming from the side not dropped square downward force. A cage with multie points of sidewards front rear support would be better.. Each car is used for different reasons.. Daily/weekend driver I would use the M bar.. With a monster like Fresh is building for race I would want more.. I have built and driven a Monster 5.0 MX5 thing can happen fast with it.. There's a bar for every seat use..

It is blue book spec and is bolted in so it could be reused if the chassis gets bent. And SCCA, formula d, HPDE, and other organizations says the bar that comes with it is illegal due to more than 180* of bends which to them and other us based agencies say is structurally deficient. being used on the street alone is a good reason to have a full cage. while yes, the track is much wider, idiots that you drive with are just as dumb, and if someone hits you, and you roll, will that bar hold up? all im saying, is for the small cost to have a few bars added, and a main hoop which is in compliance with racing regulations (already was told by 3 autocross groups they wouldnt allow my car with the stock M bar) makes this car that much more usable for the fun it was intended for. The roll bar has been designed to hold up in a roll. Probably not a multiple roll but that's just the way things go. A cage would be difficult to use in a road car.

Trackday/race, absolutely. Road... not so sure. This isnt a street car For all intensive purposes, it is really a track car adapted for the street. deisgn that i am using, along with the rear hoop type that kevin has, a front link bar, and a kinked top diagonal bar as in spec miata for head room IMG_2369 by Flsimages, on Flickr will be welded straight to the main structure as the way the track cage that is offered is not safe bolting to a sheet metal floor and the loss of legroom edit: this is the cage i want basically. saw in a recent post

I can see how getting in and out would be difficult but if i am only using it as a weekend country driver, I am not real sure I would need full cage. I do like more protection though. I have time to think about it I guess.

if you plan on autox, make note of my observation as well.
however, if you only plan to drive it to the country club and back. have fun

Freshlikesushi, our bars are not empiracle designs, the bar is bolted to a steel floor, it is reinforced at these points, you continue to make suggestions that this is not safe, your design does not even reach the floor! That would not be acceptable in the UK. The M bar is not for any autosport but offers a degree of protection as do most modern open top car bars or style hoops as they are known. I suggest you stick to building your car and restrain from using this forum to criticize.
