I "invited" the legendary Nicky Grist to be the co-driver in DiRT Rally. We only did recce for Oberstein but there are more stages to come (thus version 0.1 ). He didn't call distances because he felt that he should behave exactly as he did in the original Colin McRae Rally.
Replace the file 's_cd_panzerplatte_rally_01_fwd.bnk' located in ../DiRT Rally/tracks/locations/germany/panzerplatte_rally_01/fwd/banks/enUS' (or fr/de/it/es if you play in different language) with the one from the package. If you want to go back to original co-driver simply change the language in Steam or backup the file first.
This mod does not alter physics of the game.
Obviously I didn't exactly invited Nicky for this project so credits go to Codemasters for Colin McRae Rally (voice samples) and DiRT Rally (awesome game).
