I usually just drop my headrest all the way down when I'm autocrossing or at the track. It seems to fit my helmet just right when I do. I have it tilted all the way forward though for normal driving and don't change the tilt when I push it down for the helmet. My main problem is with the helmet hitting the celing since I have a long torso. I have to open the shade on the sunroof to give myself a bit more clearance since I can't stand reclining my seat that much to make the helmet fit.
