2010 Red Bull RB6 Soundmod 1.0

I tried to make a sound for the 2010 red bull rb6, i need to improve the downshifts a bit i think.
IN THE .RAR FILE THERE ARE 3 FOLDERS RESPECTIVELY FOR:
Cimmerian F1 2010 conversion by codemaster;
Standard Cimmerian F1 2010;
SDD version;
In each folder the sound is the same.
