Hey dude
I know the guys that run bleedingedge racing ( nt naming any names )
And one of them built me a awd mini z because I traded him 1:12 pan car.
If you don't want to have anything to fast then stick with a pn70 turn. Its the stock class motor and it fast enugh but if you want moore speed then use a atomic stock. I recommend using Orion 900mah cells for practicing and Orion sho750mah (super high output) for racing or doing timed runs on the how fast are you? the lower the nah the more punch in most batteries. And now, tires
Tires are soo important so you need the right ones that suit you.
Of to like the front to push a little the experiment with different compounds.
Set up is also key, but don't just go out and buy every shiny part of aluminum you can find because this is not allwYs the best option.
But so you can abuse your car you shout get some aluminium nukles of some degree ( forgot what mine are ) and youl probably need some different spring rates as well. And the body either needs to be a lemans sort of one or get a vds ( I prefer the short awd chassis ) so I. Guess that's the short mr03 aswell. I like it short so I can get around tight tracks and with it being shorter it's alot twitchier ( < is that even a word?) and will spin eisyer.
I know I rambled on loads and there was not much detail but I hope I helped
