Use rims that normally will not fit:
------------------------------------
Certain cars can only fit so big of a rim. For example, the Miata
can only fit 17s, but if you get a car like the Skyline put 20s on
it and trade it in for the Miata. The Miata will now have the 20s
that the Skyline had in it. Do not try to install any other rims
on your new car because the rims will go back to the maximum sized
allowed.
