# Castrol SRF Racing: 303°C


I've been using ATE for a few years now with pagid pads and i never had issues. Only that the paint on my calipers have become gold
That is the dry boiling points - now quote the wet boiling points for each one .

# ATE Type 200 Racing: Wet boiling point 198°C
# Castrol SRF Racing: Wet boiling point 270°C

As to changing SRF annually that is a total fallacy - I have had mine in the S2000 for 2 years, in the Escort for 3 years and in the CSL for 3 years, with no drop off at all (but then if you look at the wet boiling point, you will see why that is ). You're more likely to need to change any OTHER fluid more frequently due to the reduced wet boiling point figures, where the SRF remains temperature stable for FAR longer.
