### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Still going on strong
  

*by K***E on Reviewed in the United States on April 8, 2014*

After ATE superblue was out of the question and justifying some Castrol SRF, and ran Motul RBF600, I figure to give some Prospeed a try.  So far I have no complaints after many miles on the race track.  It's certainly overkill for even an autocross car, but it's definitely not spongy at all and it has been working well for me.

Best brake fluid so far. Good pedal feel, no fade, a little expensive...
