I just got my first B44.1 together and have a few questions.

1.) For my front tires (jconecpts double dees), they gave me full rear foam. Do I need to cut them down or use the full foam as is?

2.) What is the proper settings for the front diff, back diff and clutch?

3.) My hobby shop doesn't carry parts so what parts should I expect keeping a stock of? Any must have hop ups for the b44.1?

Thanks!
