RBF-600 is good - daily and on track run well. I also replaced my clutch fluid with it in an attempt to stretch out my oem clutch slave... the dark fluid over time tells me its going to die a death of a thousand razors anyways.. so be it
Ive got a HS CSC and a new MC ready to drop in when my twin disk goes in ( when the turbos go in
) <---rant
Just get a brake fluid tester for 20 bucks to check it periodically...
On track, after rbf600, and carbotech brake pads and some federal 595 rs-rr tires, my weakest link was the "ice-mode" programming trying to kill me (until i figured out how to avoid triggering ice mode)
Daily, you will never know its in there.
