per Martin Hofer:
"I like to only use 1 of the big spacers per big gear instead of two as according to the manual. The missing big spacer needs to be taken in mind, when adding shims to the outdrive. Therefore I use 3 small ones in stead of 2."
1 big spacer inside, 3 little spacer outside - will building the gear diff in the above manner hold up for MOD racing or is that for stock racing?
