SlotForum banner rear wheel grub screws too tight

I've just bought a new Audi R8C (CA12C) which has had its rear wheel grub screws over-tightened in the factory. I've ruined three new allen keys trying to loosen the screws, only have two undamaged allen keys left and don't want to ruin those. I need to loosen the grub screws to reposition the rear wheels, which have been fixed too far inboard at manufacture.

I've tried alternately gently heating and cooling the axle and wheel assembly, which succeeded in loosening one screw, but the other is still jammed tight. Any ideas how to undo it?

Apparently these grub screws have been tightened too hard at the factory, an issue for quality control.
The Slot.It tools apparently also aren't always of top notch quality, as can be seen in this this old thread.
