Took the Z4 out to RA for its redemption arc (after spinning a rod bearing there back in August '22). The car held together reasonably well, though the engine eventually reached a coolant-temp-induced limp mode.

The Accusump oil accumulator did a great job protecting the car during sharp left corners, which were causing pressure drops (a hint as to how the engine failure may have occurred the first time).
