Tricks to adjust camber plates without removing struts?

[Stroked & Blown]

I want to make some slight adjustments to my camber plates (K-Sport) for this AX season, but I can't seem to get enough torque on them through the strut tower hole using a ball-end allen key.
Does anyone have a trick to do this that doesn't involve cutting the strut towers or dropping the struts entirely? I'd like to be able to fine-tune at the track, but I'm not going to take a sawzall to the strut towers.
