You can beef up the drivetrain as much as you want but when you crash something has to give, whether it's the bevel gears, spur gear, or CVD bone. I suppose you could argue that when you crash the tyres will give, yes they probably will, but not all that much unless you have almost no grip at all!!
I suppose if you go really over board then the only thing left to give is the thing you are hitting, but if that's a brick wall then that's not likely to happen
