It's the wet boiling point that really matters since that's what will affect your pedal feel. Mu is a little cheaper.

It's too bad LeMans_Blue isn't here anymore. He'd give a NICE summary about brake fluid.

Yeah, I like how Project Mu is cheaper than SRF. It has a higher wet boiling point than Motul RBF600 for about the same price. I can't justify the SRF price.

I used to burn RBF600 brake fluid regularly on my old Evo on track so the Project Mu was a good upgrade. Those cars are much harder on brakes than the M3. The factory Brembos are way undersized for the application.

Edit: Looks like Project Mu G-Four's price is now higher. It used to be about $30-40 for a liter. At the current price, SRF is the better deal.
