When should I use Class name overrides?

Class name overrides are used only in very specific situations:

• You need more/less/different classes than what iRacing provides.
• You need to run different class sets at once (for example DP/GTE/GT3 and at the same time as ROOKIE/REGULAR/VETERAN).
• You need to exclude cars from the standings: when using 1 racing car as the pace car you don’t want it to appear in the standings (set pace car class to None in all Class sets).
• When using an official race for a league and you want only league drivers to appear in the standings (use class set 2 or 3 and set Class name 2 or 3 for all drivers to display).
