Tearing cv joint boots

Just got back from another DE at Watkins Glen this weekend and noticed both outboard cv joint boots with tears in them.
====the car is a 79 930 with stock suspension/torsion bars. Stock ride height so needless to say it squats and dives badly under track conditions.
I replaced the passenger outboard boot 1 year ago with the same issue and now it is torn again.
My analysis when rotating the wheels with the car up on jack stands at full suspension droop that the folds of the cv joint are rubbing on themselves alot. I am thinking that under severe droop and squat that the rubber boots are tearing themselves because of the large deflection.
does anyone else have experience with this problem? I am tired of changing cv joint boots on a yearly basis.
It also seems to be isolated to the wheel side boots only as the tranny side boots are fine.
