Castrol SRF

Are any of the members that track their C63 running Castrol SRF brake fluid? I'm going to start running Hoosier R6s on the car for track duty this season and know I'll be working the brakes a bit harder than last year so I'm thinking of taking the plunge.

I ran ATE Super Blue & ATE typ200 last year without any noticeable issues, but think the higher boiling points might come in handy when dispensing with those M3s at the track. Looking to see if anyone that is running the SRF has noticed a big difference from the change.

Firmer pedal than stock, but after a track day it was not as firm as when it started.
