Cat sx spares

[Chris Lovely]

Hey guys,
Just returning to the off road scene for a bit of fun really. Though I do like to be competitive.
I've got myself the new Cat sx lipo version, and I'm going to be doing the worksop events.
What spares would you reccomend me getting as essentials or basic spares.
I would just like to know, as I know I'll break sumit

thanks
Chris
