Petty bars have killed a few in the kit car world, I would avoid.

How? I thought about the pettybar Beeing very long without support. But if you support it maybe just in front of passenger seat? Br, Per

Side ways impact whipped the passengers head against the top of the bar, the impact was so severe the helmet didn't save her. Make sure your head can't hit the cage no matter how hard you try, cover any possible impact points with FIA impact foam.

That is really sad to read Steve 😞 What data is there on impact with cage that has the fia approved foam on and no helmet? But agree in design cage to be out of impact range where possible DG

Sounds like putting a cage in a VX/Elise is so expensive you'd be better off just buying an ex Academy Caterham which has everything already done, cheaper tyres and brakes too.

Clearly this is aligned to Steve's way of thinking!

My view is that on a trackday you should never be in a situation where you need a cage in a VX. It is not a race - car to car contact should be almost impossible and unless you drive beyond your limits you shouldn't hit anything...

What a strange thing to say. So if i take that corner in 160 kmh and the toe Link or camber bolts snap for example and I slide around and hit the graven and car turn upside down like I saw a car last year do. How could I avoid that, I could drive slower by alot or not track the car at all. But this will not keep the discussion going forward. Br, Per Axblom

Apparently the foam is the equivalent of wearing a second helmet but even then when I made my bag seat I made it so I couldn't hit my head on the cage or padding regardless of force, best to be sure I think.

Agree to a point that you shouldn't need a cage on a track day but as mentioned when components fail a cage can save your life. https://m.youtube.co...h?v=SWF9dJi3FaU

Been upside down on fire in a car before it can happen.........

if it makes you feel more secure and allows you to go a little bit harder and faster and brake latter before that bend then do it.

Racing (trackdays is a mental thing)

Lots guys come in when it rains ...................

We all drive fast on the road when its wet I quite often do 10000 leptons on the straight motorway in the rain.

 

I wear a fire proof balaclava under my lid but only to keep the sweat away from the lid.

Some guys have an extinguisher in the car.

 

The cage will add weight and will maybe slow you down unless you don't eat the day before and then have a good old poo before you track!

 

I crashed at Cadwell on an intermediate day (which I wasn't) 

 

Better to have a good lid and gloves and boots.

 

Top of the list of things to do is have a fcuking lesson and learn the circuit ....this will get you faster and better and more confident on track.

 

I love Bedford because its safe and I have done 5 days there so I feel I know it and don't feel intimidated by it.

 

Just keep going and don't turn up thinking your a racing driver ......were not.

 

its a track day

It obviously doesnt matter how good of a driver you are sometime you loose it and then the acciden is there.

 

So, which is the best combined saftety for a car used both for trackdays (where accidents can happen) and on the streets.

 

The idea from myside is if you have a petty bar then you can easily remove this after the trackdays.

Ths is really bad, but it wasnt because the petty bar collapsed?

I thought you couldn´t even have petty bar and passanger at the same time.

 

Anyone having any idea if this could fit into a VX220?

http://www.elise-sho...2-p-502493.html

 

I hear ppl saying the VX220 roll bar is weaker than the one in Elise S2 and S1, anyone knowing the difference?

We are fitting a safety devices cage to our MGTF160 track car..removed from a mgf cup car..so will let you know

[siztenboots]

we often do trackdays with the roof off , some circuits insist that we run full face helmets. to avoid arms/hands being trapped if the car is upside down in the gravel, some circuits insist roofs must be fitted all good common sense stuff, but motorsport is dangerous due to mechanical or human failure if you avoid some of the trackdays companies that give drivers no rules to obey, then you can at least drive with friends who respect other cars on track.

Indeed, It is mandatory in Caterham racing to wear arm restraints to stop this.

and mandatory in the Netherlands for all racers IIRC.

 

Safety is very much a state of mind and we can't be authoritative without testing, which won't happen, but in my experience from a few years of racing;

 

A plumbed 'fire extinguisher' is merely a fire suppressant for a short period.  All it will do is quell the flames giving you time to exit the car.

 

A 'roll cage' should be called an anti-intrusion cage.  They are mainly of value in side on impacts (another car into the driver's door), when they are life savers

 

I've seen several 'rolled' cars that did not damage the roof during the roll.  The usual mechanism is that the car gets sideways, tyres get stuck on grass or in gravel and car flips over, coming to rest back on its wheels, with limited force applied to the roof.

 

A Petty bar is merely a roll bar reinforcement.  Is our current bar that weak as to require reinforcement?

 

The most common cause of injury is failure of the seat or seat mounts, allowing the driver to move around in the car.  Belts need to be correctly secured (and not to the seat) and the seat needs to be firmly attached.  When the seat fails, your roll cage is no longer your saviour!

This looks dangerous. Id never drive with a pettybar and passager at the same time.
