Wheel nut

Porsche Motorsport also recommends replacing the wheel nuts during a long
distance race (approx. 6 hours run time). The replacement is required for checking
and regenerating the used wheel bolts. Regenerating includes cleaning of the
threads, visual inspection for damage and re-greasing with aluminum paste. Also
grease the nut-rim contact surface. Proceed as follows to prevent the wheel nuts
from settling: Tighten the new part 3 to 4 times using an impact wrench (500 – 520
Nm (368.8 – 383.5 lb-ft)), then untighten and regrease.
