just wondering if anyone uses this DOT4 synthetic fluid...it says it's compatible with any brake fluids, so i bought a couple bottles, gonna flush the old crap out and put this...

anyone have any problems with synthetic brake stuff?

 

I've run it in several cars and had no problems. It did not have a high enough boiling point for track use on the gsr but was fine on my old rx7. Street use, fine, and never saw any problems mixing with whatever was in the system before.
