M14x1.5 Another one delusion
Concerning BMW differential typ188
It seems to be a popular fallacy in the north (UK and Scandinavian) that E30 has M14x1,5 on the crown gear bolts. Each typ188 has bolt size M12x1.5.
I have been doing with differentials for years. The only differential type188 with M14x1.5 I’ve ever met is the BMW E36 M3 3.0. Also in the official documentation of BMW is invariably present thread M12x1.5 of gear ring bolt.
