from what i have seen of this NEW toxic accords side rails i personaly would advise against leting it run in nationals as i deem it out of hand!i know i may upset toxic accord for saying this but its my opinion that it should not be aloud.!!!!!!! as i bealive it would send the wrong direction of the course! mind you its up to john of course.
John, just one modification to what i had. it is similar to the rub rails on the back wheels of blue thunder . But because the front wheels turn it is shaped to allow the wheel to do so. and I did make it a bolt on, so it can come off . there would be no need at all to have it for the bone stock race because there are no barrel turns. the Honda front end is very weak. and the local junkyard is running low on upper control arms...lol

We'll have a look at it together. I'm trying to get a feel for whether it's "Red Baron-Type" rails (where were connected to their modified bumper assembly) or whether this is something different all together.
On a technical level the rails really shouldn’t extend outside of the body of the car - - although we have seen these tested on the <<back>> of Blue Thunder and enjoyed what most would consider good success at protecting the back ends of that car and since they are on the rear of the car, there is absolutely no chance of them being used offensively, even by accident.
The rub rails have long been a learning-curve for the series - - the Red Baron pilot project car lasted a full three seasons, and the first independently built car, Snot Rod (Snotty) is still in operation. Both had decent rub rail systems from the beginning which greatly extended their run.
It sounds like you know that this bolt-on will be trouble for the Bone Stock 75 - - but I am curious to see what it is.
Trivia side note - - in the states there are some similar series to the Chaos formats. They have been known to actually run 360 degree rub rail systems around their cars at a set height (think bumper cars). This is not being currently considered for implementation (at all), but it is an interesting note considering the Blue Thunder-Type rails we have seen.
Hoops are both a good and bad thing in any racing class.
For bone stock, having ancillary support behind the factory bumper is probably a good compromise.
The physics of a 2,000 + car in motion at 50 Mph and if it came to a sudden stop (say the wall) with a direct frontal impact creates an energy dissipation requirement in excess of 18 tonnes - if the goal of the hoop bar / bumper assembly / attachment points are to disperse the weight away from the driver, adding a hoop bar is smart idea.

This is an entry class, safety should be priority #1 - or we won't be racing much more if race track insurance rates skyrocket (meaning higher entrance fee's). Several years ago at another race track that ran "stock" cars, it was getting out of hand and could have been a disaster and thankfully is no longer running at that track.
83 tonnes, i think that you typed a number in wrong, either way it is a lot of force and they need to do something for saftey
This is much to the point I was making in that if you look at some vehicles that have had allot of gutting done, you would see a reduction of materials to absorb the impact energy. This may not apply so much with FWD cars as you really can't gut a whole lot out of them, but then you see why supplimental restrainst systems are so important in a street car. I do recall a situation where at a neighbouring 1/4 mile track, a FWD car hit the wall and the engine cllopsed the firewall trapping the driver for quite some time. Now it was about a 1984 or so K -car but it happened none the less. A few extra bars go along way in improving driver safety. I understand the hope here is to have fun but please lets think safety and remember a $2000 carbon fibre helmet will not save your life in a poorly built car.
