yea, of course i have replaced all the bearings to the ball raced. also, i have changed the shaft. those were things my friend told me i had to have. he has a tt01 too. but the bearings are a must. for all my mini's i've got bearings in them too. Thanks a lot. i did what you said and all i can say is wow!!i'm trying to set this car up for only drifting. very fun
thanks again. HUGE help.
