It'll be the tip of the shock tower digging in, then flexing/breaking against the spur gear cover mounting lug. I broke ~half a dozen plastic towers, then about 3 or 4 carbon ones.
Spacing the tower out from the gear box with 1 or 2mm shims helps, makes the failures far less frequent. But you can see witness marks after big crashes...... i think it is a design flaw with the car TBH
The RDRP aluminium tower is unbreakable. Buy one and never swap again. It doesn't seem to cause any problems down the line either.
(There is a fairly sizeable thread on this i started about 2 years ago.......)
