also to note the old b6t box i was running had a 4 spider competition mazdaspeed LSD clutchpack in it with a custom straight cut 3rd gear.. first i blew the straight cut 3rd ..the lsd was fine that would never break, however the bearings in the g series are just too small and it blew the case in 1/2 literally..
heres the blown 3rd , it was a locally made gear , next to it is the PAR 3rd gear which i think is alot beefier but its alot more 800AU$,.. i dont think i would have blown that 3rd however when the bearing let go it would have destroyed it anyway . the main bearing that ive found to go is the one on the end of 2nd shaft next to the crown wheel there..theres a pic at the bottom of the damage its very nasty..hehe
it also blew both the end bearigns straight thru the case, have a laugh..sorry about al lthe pix but it is amusing
