Just checked Mahle pistons sitting on the bench, these are 86mm+ .040'' and
they weight 676 (1) and 680 grams (3).
What is the weight of the stock pistons, and the weight of the Hepolite, or
from other reputable brands?
Cheers!
Alex

Good information Greg. I remember weighing a set of these Mahle pistons
years ago and could not believe how heavy they were. Never used them.
Hepolites were my fittings.
