It has no diagonal bracing (other than the glass itself), and no bracing, just the frame. Second, any rollover also has the same potential with the windshield bending back over the driver. While it comes up a lot, a little research shows a couple facts.įirst, rollovers on the street are very rare. Posts on this topic will inevitably bring up "mousetrapping", which is a concept that an unbraced bar can move forward and trap the passengers in the seats like a mousetrap. It works fine with the soft top and stock storage bins. I didn't add it for rollover protection, but for more bracing. But the mounting is very sturdy, unlike a lot of style bars that have no bracing at all. I have an Autopower rollbar that is structural and added a lot of stiffness and is well built, but they call it a "style bar", probably for legal reasons as it doesn't have any diagonal braces and isn't approved for racing. A roll bar is designed to enhance structural integrity and add safety in a rollover. At least that bar is approved through SCCA, so you can use it should you ever decide one day to attend an auto-x or HPDE event.Īre you looking for a "style bar" or a "roll bar"? A style bar looks like it might do something in a roll over, but probably won't, at at least nothing good. The Techno Pro-Spirits bar will not protect you during an impact or roll over.īuy the Hard Dog bar if you want a rollbar. There are no extra bars to support the main hoop, nor is there any triangulation in the design. Rollcages work by displacing the load of the impact through the many supporting bars that make up the cage, they are also reinforced through triangulating the design. I've defended many Japanese bolt in rollcages in the past, but I will not, and cannot defend the Techno Pro-Spirits roll bar. These are the same dudes (Japanese people in general) who think it's a great idea to go wheel to wheel racing with their "fuel cell" being a lawn mower fuel tank (just the bare tank, no bladder or impact protective box) relocated to where the passenger seat would be, with the battery (no box, just a bare battery with a tie down mounted to it by drilling some holes in the floor pan) relocated right next to it. Unless it's a pro race (I'm talking about ones that go by FIA regulations, and not JAF), there are damn near zero regulations governing car modifications on Japanese race tracks. If someone wants to take the time and draw one up and include dimensions and scan it on here or do it on the pc and just post it up feel free, maybe i'll do that tonight.Click to expand.That doesn't mean a thing. You guys tell me what you want and what is needed specifically so i can have something to go to him with to get this rolling. I am not sure if you need that diagnal to get on the track or if it can be like the normal AP bar plus the bars going to the floor instead of just the normal mounting location height. i think the discussion should also shift into legal and optional aspects of it, like tubing dimensions and mounting locations and if it would be welded or bolted to the floor. number to figure out the best possible price. We will need some sort of real number before it comes time for real pricing tho, would need a min. so the only real interest that can be shown is if you guys keep this alive and remind me again in about 2 months and all the people are cool w/giving some sort of a deposit for a certain number of them made (maybe 5-10?), we'll talk about how many of them and price when i get a legit estimate made, but for now, if you guys want to keep this alive if your serious about wanting them done in a larger number then i'll make sure i talk to them doing it. So i think i MIGHT possibly be able to get something like this done when im back home, could be a few months and take someone else (joey) w/a spyder and a softtop still in order to make it happen, but i know some of the best cage guys out there and i have full confidence they can make something like this happen, if not on a production level then they can atleast bang out some sort of a group buy, i know they wouldnt push the business away. Well, sorry to hear its not gonna work out w/AP, i went thru the same deal w/them already i think i told you guys, hoped it would work out for you different now mike but i guess it didnt.
