All I know is that transmissions (2-3 per season) were a consumable when I ran redline in them. After I switched to Royal Purple I have not had to replace a transmission in 2 seasons and the grinding has ceased. My driving style is unchanged, if not more aggressive.
Redline also ate up rear ends. I am one of two people I know of that has broken an open rear end in circuit racing. My motors I religiously changed the Mobil 1, rings lasted 1 season (figure like 5-10 run hours?) With Royal Purple that hasn't been an issue.
