to be champion depends.
world champion,national champion,regional champion,club champion.
i won my local car championship but all i got was a trophy and dint have any special equipment.
to do well anywere you need knowledge,driving skill,backup and of course money.
now were we won the championship we run stock motors.
so i had bout 5 stock motors for the whole championship.
at the time we were aloud bearings inside so the best bearings i could find were put in.
but i had to have knowldge of the track ,grip and size.
which i did.
basicly money isnt the only key factor but 1 out of thousands.
everything has to be taken into consideration.
car prep etc.
