For racers and weekend club drivers, the Arrowmax AM-212021 Silicone Differential Fluid 59ml 1,200cst V2 provides predictable diff behaviour. The specified 1,200cst viscosity gives stable damping that helps control slip and improve cornering balance.
The compact 59ml bottle covers several diff services, so you can test different settings without buying large quantities. It is useful for dialing in the rear or centre diff to match surface grip and driving preferences.
Clean the gears and bearings before filling to avoid trapping dirt. Apply the fluid carefully and run the diff through its range to work out bubbles and settle the oil for accurate tuning.
