Ok, so I'm thinking about getting a cage done eventually, but I'm going to do some research before I go through with it. I was wondering if you can do a cage with a full interior?

A/C has already been ditched. Heat will be retained. Radio will be retained. Other weight savings comes from the replacement of the stock catback with a Corksport.

Mind you, this is a going to be a fun car for the street with maybe some track time. But the main purpose is to make this car a bit more safe.

Planning on wearing a helmet all the time?

Street cars don't need roll cages.
Street cars don't go through weight savings regimes.

To make the car safer:
-Upgrade the driver
-Good tires
-Good brakes
-Good suspension

a full cage w/full interior is kinda silly, what would be the point? .....i say this, but I definitely saw an executive in suit and tie driving a fully caged E30 m3 to work and I must admit it was pretty badass.

I've considered a half cage (just the rear part) mainly as a harness/camera mount. But a full cage offers no benefit in a street car and a full interior offers no benefit in a track car so...

What if you have a race car that you drive on the street. ? What if you have a 10sec/9sec car you drive every day. How do you go to the race track with no cage? Real men have full interior panty wettersGuess ill get my photo album out post wreck street cars with cages that saved friends lives.

I'm about to do a cage and keep as much interior as possible. Car is going to be driving to the events. I will have a back up trailer, but I prefer to drive the car to events.

I have a buddy with a E30 and the half cage. It's decent, but of course it's gutted... I'm going to be keeping the door panels and rear bins. I'll cut a hole in the dash, side bars will be installed for events. It may not be an everyday daily driver anymore since it's way to fun to not be on the throttle...

I don't care for gutted interiors unless its a full time track car. I can't seem to find a thing wrong with a cage and full interior, if done properly it'd look real nice.

a roll bar is more suitable for a street car, a roll cage(full cage) is for a dedicted track car and has no real purpose on the street except making you LESS safe.

i plan on putting my autopower roll bar in my car for street driving which has attachment points for a full cage which you could put the 6 points in while at the track. the bar sits behind the seats so no worry about mashing my brains into it in case of a rollover.

anyways, take a look at the autopower bars/cages if you plan on driving the car on both the street and the track and have settled on putting a bar/cage in the car.

edit: at least they did since i have the attachment points on my race roll bar which they seem to not have a picture of

mine has 2 more attachment points at the top corners for the slide on 6 points.

Main thing to consider: Ensure the driver and passengers won't be put at risk from hitting any roll cage/bar tubes in a collision when not wearing helmets. How will you accomplish this?

Strap your *** to your seat like your supposed to and banging your head on bars arent to big of a problem. i have been in a accident with a cage, i was not strapped in i just had the harness lopped across my chest like a regular seat belt. driver was strapped. he was fine, i banged my eyebrow up pretty decent. When i speak i speak of roll bar/cages . To me a 6-8 point is a roll bar type cage if that makes sence.A age (to me) is a 10 pont + then you get serious at getting in and out, manauvering ecomes a problem, working on things become a problem ect

OP. are you putting the cage in the coupe or vert?

GeenIdee

Are there guys that can post detailed pic's of their rol bar's?

I've got the idea that you will lose space to slide your seat back and i dont know how big of a problem that can be.

And are there any others then the cusco or autopower?

I am also having this in my mind for later on.

that's an idiotic way of thinking about a roll cage..

anything above and around your head is a "cage". anything behind and above your head is a bar.

Evil Aviator

You could do that, but some of the dashboard will need to be cut off by the side window defrost vents if you want a decent amount of clearance for your body. You could put it back together and maybe cover the cut with upholstery, but it would not be safe to simply S-bend the front hoop around the dash like you see on those ricer fake roll cages. Also, it would be rather difficult to install the side bars without either reducing your body space or encroaching on the interior door panel. See the SCCA GCR roll cage specs for a good example to follow.
http://cms.scca.com/documents/Club%2...CR-January.pdf

Also note the proper seat and harness guidance in the SCCA GCR. I started out with the Latch & Link type harness buckle, and after years of accidentally pinching myself I swapped over to the Cam-Lock type.

In order to keep from injuring yourself in a collision, you will need to put foam on any of the bars that may contact your body. FIA is the best, SFI is very good, and the regular cheapie foam stuff is at least better than hitting a bare metal bar.

You may also want to check your local laws to make sure a roll cage is legal for street driving.

I disagree. His entire post was idiotic, especially the part about not even wearing a harness.

Were did you read the part about not even wearing a harness? fill me in please? Also i like the constructive critisism coming from this thread. I have not seen a rollcage thread with any good info. Also wondering why im so "idiotic" by my opinion? Please explain in detail.

yes theres many others, S&W cages, and after xmas i will be seeing how a very common car roll cage (6 point) fits into a rx7. its 230 bucks! for the cage.

I do know the main hoop demensions for the vert Griffin, If you have a way to cut tubing, make mouths, and a welder you can get a cage not made for the rx7 but has the same hoop demensions.

Autopower is OK for occasional track days but I dislike them for a "serious" track car. Completely useless in a street car as the compromises they make to make it a bolt in mean heavier tubing and a lot of joints etc.

Cusco is crap IMHO, and its probably better to just not have a cage than have a Cusco.

I can post some cage pics at some point, but wander over to the race section and theres a whole thread with peoples cages.

typing to fast, not proof reading, As i stated right after that i was strapped in but not properly. Anyhow back to roll cages and not harnesses.

Does anyone posting in this thread have a rollcage/rollbar installed in there car atm?

Evil Aviator

Yes, my 88 coupe has an SCCA IT cage with NASCAR style side bars, but not much interior.

Pics without the SFI pads installed:

The cage or roll bar will be going into an 87 Coupe, that is if I decide to do one. At the moment I think a Roll bar of some sort would be the right idea for a street car that occasionally sees track time. But the question is how much interior would I have to compromise to have one.

Evil Aviator

I think an Autopower would be OK for the street, but I do agree that it is not an optimal design due to the bolt-in feature. However, some people want a bolt-in cage, and in that case the Autopower cage is a good choice. I remember back in the day when one of my local racers would rent a Mustang, install a bolt-in cage by cutting the carpet and carefully peeling it away. He would race the dogsnot out of the car, remove the cage, carefully replace the carpet and glue it back down, and turn the car back in to the rental company, lol.

Cusco is only for show. S&W is not legal for SCCA, so personally I would pass on that one.

Mine is a custom weld-in-place cage that can't be removed intact. If you have one like mine sitting in your back yard, then it is scrap metal.

Oh, with just a roll bar you wouldn't need to cut up too much interior, depending on how you do it.

If you look at this picture you will see the preferred design, which involves placing the hoop as close to the roof as possible (and welding it to the roof if legal for your racing class), and mounted to the rear shock towers. At minimum, this requires removing the headliner and cutting holes in the plastic trim that goes around the shock towers. The hoop is affixed to the floor, but you could simply cut back the carpet in a flap and then trim the flap to fit around the footing.
https://www.rx7club.com/attachment.p...6&d=1191035819

If you are OK with a lesser roll bar, you could design a lower hoop that would clear the headliner. This obviously wouldn't be as safe, but it would be better than no roll bar.

Another option for the rear bars is to attach them to the floor of the trunk rather than the shock towers. This way you could cut back the carpet and re-trim it like you did for the base of the hoop. The plastic trim would stay intact, but the downside would be that it wouldn't be as strong as a shock tower attachment, and it wouldn't help handling as much.

Although S&W is not SCCA leagal (idk what OP is racing in) Its legal for drag racing, better than nothing, and will probably save your life. Not the prettiest either.

I have a convertible, I cut the roof off the coupe, cut around the plates for the cage slid right out. If you have a convertible you can get the cage to weezzzle in perfectly with a little elbow grease. So i (Me, Myself) would not say its scrap you know how much it cost to get one made im sure.
