Any ideas on how to get this undone?!

what amount of force do the mechanical tighteners have? why can't tyre shops just have something that's rated to a specific max torque so that humans can actually undo them?
Why can't they use a torque wrench and do the job properly?!
Your best bet is going to be what has been suggested previously, taking it someone to whack them loose with a big airgun.
A technique I don't think has been mentioned is to put the end of the breaker bar against the floor, and drive the car so it pushes back against it (obviously, choose a direction that equates to undoing the nut!)
I've twisted a crossbrace as you describe thanks to a similar situation, but the nuts did come loose.

The bar flexing is not good, it's absorbing the force, that's the trouble with breaker bars 
I used to have this issue with van wheel nuts till i bought a cast wheel brace as below, with the extention, never had failed to remove a wheel nut even on 7.5 tonners.

You can get them with the extension for about 40 quid from a decent spares shop.

Had the same problem last week. One or two on each wheel.
A normal wheel brace wouldn't budge the nuts. Scaffold pole on a half inch drive did nothing except make my shoulders hurt when the T bar broke. I was defeated.
Later in the day a mate who is a car mechanic visited and tried his impact gun. Nada. So he jacked up the car and rotated the wheel and as it was moving he then pulled back on his breaker bar. They all came undone this way. He explained it was the weight of the wheel acting against the nut that undid them.
I laughed at him at the start, stating no way would it work.
I was rather full of humble pie after.

To be fair though, on my Kwak 636 to get the front sprocket off they tried everything including lots of heat and it was eventually loosened by 3 big blokes and a 6ft piece of scaffold (I was there watching - super scary!)
I had the same thing on my wifes factory fitted sprocket on here ER6f. We tried everything, impact wrench, breaker bars, 4x2 between swingarm and wheel, we were lifting the bike off the floor despite two people sitting on the bike. Was ridiculous. Ended up taking to a friendly mechanic mate, and he managed to do it by getting leverage off of the "external face" of the nut, rather than the one that should have been used. I know my mechanic mate doesn't like to fail, but when he said give him 15 mins, I disappeared for about 3 hours, and I know he only just managed it before he got back, even if he told me differently!

if you really want to get it off, lie on your back and use both feet to push upwards.
Most people can exert 2-3 times their weight as power in their legs.
On a 2 foot breaker bar its not that hard to a create 1,000lb/ft of torque- you also have considerable movement in the legs which means you overcome the bending in the bar.

Always lift the breaker bar up rather than pushing down on it. Pushing down the max effort is equal to your weight, Lifting it increases the effort by the strength in your legs.
Also reduces the risk of smashing your knuckles into the ground as the nut / bolt loosens off.

The only thing that'll achieve is a dirty back!! I'm bending the tools so applying more force isn't the issue I guess.if you really want to get it off, lie on your back and use both feet to push upwards.

What I need is a method to undo the bolts without f
king more tools up or the purchase of the correct tool. I will try the beating it with a hammer thing.The vehicle is undrivable currently so can't take it to the local tyre shop!
Was the impact driver you've tried up to the job? If not, could you hire another one maybe?

I'd try giving it a whack as suggested below - otherwise it sounds like you'll need to drill them out.
It must be very frustrating....
Maybe worth calling a mobile mechanic?

or buy a better tool- i know you don't want to, but if you are bending a break bar then buy a better breaker bar.
I have an old 3/4" drive 3foot bar that i've pushed huge amounts of torque through using a 9 foot extension
