What you the circuit racers amongst you recommend for a 2013 Mk2 FG NA with a ZF auto suggest. Car will mainly be doing sprints, 5 x laps of Barbagallo, Collie etc and Targa Rally Sprints. Eventual plan is Improved Production, but for now just the small stuff. What Oil for the engine would be best suited. 10W60 ? Perth WA , so it gets hot in summer here for sure. Winters not too cold.
