Mate, really... you should know that by yourself, it's even on front page of THIS VERY SAME MOD ! Just click "Overview" tab if you don't believe me. But here it is anyway...

How to change chassis according to track :
Go to the
trackconfigsbase.ini file you can find in each constructor folder here :
GameData\Vehicles\CART_Extreme\1998 and look at the name of your track. Use this syntax for each constructor :
Chassis Configuration=0=road (default)
Chassis Configuration=1=short oval
Chassis Configuration=2=speedway
Chassis Configuration=3=superspeedway
_______________________________________
So, basically, you have to find EXACT track name, open every constructor folder, find
trackconfigsbase.ini, open it with notepad and edit, entering new track name. NAME, mind you not "Grand prix" name or something else.
TrackName = Indianapolis Motor Speedway
EventName = Indianapolis/INDY 500
GrandPrixName = Indianapolis/INDY 500 // this must be the same as event name
VenueName = CART, Indianapolis
so the right name for this track is -
Indianapolis Motor Speedway
not
Indianapolis/INDY 500 or
CART, Indianapolis
enter:
"Indianapolis Motor Speedway":
Chassis Configuration=
2
With number 2 sets
Chassis Configuration=2=speedway, that's it.
Bigger question is how did @Dann Murillo let this happen !??
