OK. What do you think is the best Li-Po Battery, Esc. and Brushless Motor set-up for the E4 and which E4 to get?

I'm looking at running the car both indoors and out on Tarmac on Rubber tires!
I'm not sure what the new classes for the Brushless are but I was thinking of whatever the "stock" equivelent is.

Pardon my ignorence about electric and classes etc.

Thanks for the help.
