Dallas, Texas, USA
All materials come from the USA.
We use 7075 aluminum which is much harder and stronger than 6061 aluminum. Most manufacturers use 6061 because it is cheap, but then spin the marketing strategy "aircraft grade". In fact there is no such thing as "aircraft grade" aluminum because aircraft are complex and use every type of aluminum.
Bolts are Grade 12.9 which is equivalent to USA grade 8.
We have tested with both genuine BMW and aftermarket crank bolts. Both fit perfectly.
No. You do not need to rotate the crank hub bolt (which is very difficult, and may require 600Nm of torque). Our product always fits.
