    Perfect product to go with my StopTech Rotors and Steel-braided brake lines. Increased peddle feel in both brakes and clutch, and won't overheat like the stock stuff.

    • Q: Difference?  Regan M5 years ago

      What is the difference between the STR-600 and 660? If i put the 660 in my DD which I dont track but do drive and brake hard will it hurt anything or does it have negative effects?

        A:  The only difference between this and the STR600 is the boiling point. The STR660 has a higher temperature rating and neither fluid will have a negative affect.

    • Q: Amount  bradroggie20228526 years ago

      Is one bottle enough to refill the entire system after draining the old brake fluid?
