Best brake fluid on the market for performance vehicles.
Best brake fluid on the market. I still change it once a year on my dedicated track car, but the fit, performance, durability, and longevity is 5/5. Value for the money is there even though it’s pricy. Can’t put a price on safety though.

Almost Expired
This is my favorite street fluid. For track cars without ABS I prefer a higher viscosity fluid like endless, but in ABS cars that makes the ABS kick in early. First bottle arrived leaking, refused. This one arrived intact, but its 15 months after its born on date. This has a shelf life of 18 month at best.

My second year using this fluid
Best brake fluid for the race track. Done hot lap after hot lap without boiling this fluid. My vehicle was 3680lb with me in it

Top of the line
Best brake fluid for racing or even on the normal jobs. I work for a race team on Offroad dirtbikes and this is the best fluid we’ve ever used.
