Definitely get a billet basket. I shattered the fingers off my stock one with a Serval on pump gas launching in dirt. The pieces of basket fucked my main gears. Same as N2O, get a new bushing for the new basket. Also, inspect the thrust washers on either side of the spacer for abnormal wear. Mine were worn and causing issues a few years ago.
Mattoon, Chariot, and Redline are popular choices for baskets.
