Since there are too many stories of
"Im using a GT35 ballbearing, i got it cheap"
"my ar70 is confirm a ballbearing turbo bt not ori"
"my ar70 spool fast, ballbearing" I am not here to spoil anyones market...
I'm starting this topic cause I see that the questions for this topic is getting more and more popular but it's everywhere... sooo I think it's good to consolidate into one topic for fast and easy reference.
