request for some tracks

i need some tracks which based on nurburgring2001.wad and Indianapolis2001.wad.
my tsm doesn't work so i have to install tracks by swapping track files.
*by the way,is it possible to rename the .wad and the .dat files?

Here is a tutorial of how to move tracks to another slot:
