The best
I replaced the OE brake fluid in my Kia Stinger with the Motul RBF 660. It's probably mainly made for the track, but I'm using it on the street. The OE brake fluid quickly boiled, so I needed something with a higher boiling point.

Great package, as advertised
This is higher rated for race purposes, which means it works better than OE dot4, but also means it needs more frequent replacement as it absorbs more moisture.

On time delivery. Works as advertised.
