I would call Dan Cragin and ask his advice as he knows your climate, the California tracks, the Viper’s strong and weak points,…AND, the fluids that work best in all of the above. Dan has prepped more Viper race cars throughout time than most techs.
Oil and filter Before and after each weekend. I do this because I may put 2 to 3 thousand miles on the car between track
days.
Brakes Complete fluid flush after 20 sessions (two weekends)
