ill take a stab at this
generally speaking :
rear wheels usually smallest possible , front wheels? i usually have a larger left front (to me it feels like the it keeps the front end from sliding out , or pushing to the right as i go thru the turn)
for a controller - steering lock anywhere between 9 and 13 , 9 being for longer tracks with sweeping turns , and 13 being for shorter tracks with tighter turns
i mess with weight a lot , i think mst people usually have it more on the right rear than anywhere else
i also mess with rebound rate a lot , depending on which front tire i want to look off of as i go thru the turn
edit to add : disclaimer - i am in no way the fastest car , these are things i do to make the car feel how i want it to feel
