I'm not sure what you mean when you say these bars are 100% legal. They are not SCCA legal and I doubt they are street legal. In fact these look like the would be dangerous to occupants if they were not wearing helmets. The bar is very close to the occupants heads. I hate to think what would happen to anyone sitting in those seats if they were rear ended without wearing helmets.
Since this is in the Autocross & Roadracing section, do you have any examples of a product that would pass SCCA or NASA tech?
What class are you referring to? Most of RPM Rollbars are catered to HPDE and drag race enthusiasts. I would say the vast majority of their roll bar configurations will pass without an issue BUT YOU MUST know what requirements your class will require. Every class has different requirement.
RPM Rollbars generally EXCEED the minimum specs of what is required for most applications.... for example most SCCA/ NASA requires only a small 2x2 foot pad.. where as the RPM pads is 6x6 and contoured to body of your car initializing a top and bottom plate.

Again... you must know your class requirements before ordering a bar. We and RPM can supply a bar that will pass ANY inspection BUT we must know the requirement of your class or it's intended use.
The bars made per to NHRA rules so they will pass inspection. Bars MUST be in certain positions as per rules. If the seat is reclined ALL THE WAY BACK it would be close to the bar BUT if the driver is concerned about hitting their head they can install rollbar padding AND move the seat forward a bit.

Charlie,
I just saw the pictures of your custom rollbar and it is NOT even a 4 point rollbar which means you cannot legally use this for HPDEs. No knowledgeable inspector should allow you to race on a track with that setup. Also, your rollbar is held together with some bolts and not welded together... it is cool that you can remove it and throw it in your trunk but there is nothing legal about the bar. Plus the way the bar is designed you cannot have a passenger AND it does not appear that the top can be put up.. am I wrong? AND lastly the the tubing appears to be ERW Seemed tubing which is the weakest tubing you can buy.

Most of what you said about my roll bar is correct. There is NO WAY to put an SCCA legal roll bar in a convertible Corvette and have the top work. The main reasons are that in order for the bar to be safe it has to be too high for the top to operate and the location of legal aft facing supports requires cutting into the bodywork of the car because (if I remember correctly) they need to be within four inches of the top of the bar, need to be at a 45 degree angle, and can't have any bends. As you said, you have to know your requirements when you are putting in a roll bar. For me I wanted a solution that would be as safe as a coupe (without a roll bar) so I could use my car at HPDEs and I needed to be able to safely drive my car on the street as a daily driver. When I was looking at purchasing a roll bar for my car I looked at all of the bars that were available at the time and none of them fit my requirements. They were all too low ( I am 6'tall), they were so far forward that they wouldn't be safe for daily driving (apparently these seats move a lot in a rear end collision), and most of the rear support structures were bent and came almost strait down onto structure that isn't strong enough to handle the load. Also they were installed with Riv nuts which is not an acceptable attachment method for primary structure.
So my Roll bar is definately a compromise, but it met my requirements to be as safe as a coupe (without a roll bar).
The only things you were wrong about were: 1) its suitability for HPDE use. I talked with several of the best HPDE groups in my area prior to building this bar and got approval. I have used it with many different groups since. 2) the material.... I can't remember the material but I brought the SCCA spec to the cage builder and specified the use of the SCCA approved material.
My roll bar was fine for its intended purpose, but as I got a little faster I realized that I needed to upgrade my roll bar, and since their just isn't a good way to put a safe roll bar into a dual purpose convertible, here is how I upgraded my roll bar

Charlie,
You are incorrect about there is no way to put a SCCA legal roll bar in a convertible have the top work.. RPM has done several but it is NOT easy. The tubing maybe legal but it's just not the best option available. Obviously your solution worked for you but it's now how I would have addressed it when I owned a shop.

BTW, is that a Radical you have?
Well I am glad to hear that someone was able to figure out how to do it... Seems impossible to me, but there are more creative people than me in the world.
Yes, I retired my Corvette to street duty and use the Radical for the track.

Sorry, I forgot to respond to this.
While private "anything goes" days may have their own standard, I would expect tech at a "real" road race organization to require a few things for a roll bar:
* Diagonal (or some form of double diagonal) bracing for the main hoop
* Fore-aft bracing that departs from the main hoop on both sides, at a reasonable angle, with no bends in it
* No crazy bends or 90* joins straight off the main hoop like this: https://cimg2.ibsrv.net/gimg/www.cor...5b82fc68e1.jpg
My comment was because I didn't see any roll bars in your original post that seemed to meet that kind of standard. If someone has taken RPM bars through SCCA/NASA tech with success wants to chime in that would be welcome, but from my perspective I see a bunch of drag racing stuff that would not pass tech with a road race organization.

RPM makes the Roll bar in any configuration a customer wants... They offer a option which includes a Diagonal SCCA Bar.
