Follow-up analysis to Car & Driver crashing Nismo 370Z at VIR

Mike

Akebonos not up to heavy track use!

I have. I was using
-Valvoline synthetic fluid at the time, (which I successfully used on my 350Z and my C6 for the last 5 years of track usage).
-Hawk HP+ pads up front (highly recommend against them on this car)
-Stock rear pads

Boiled fluid, wore the rear pads to backing plates and scored the rear rotors and halfway wore the front pads down in one 20 minute session.

Once I switched to HP+ all around, I still had the boiling problem on the same track, but a little farther into the sessions.

When these brakes boil the fluid, you might get a tiny hint of a soft pedal at the first turn, but by the next, they are pretty much gone. Its really sudden and scary when it happens.

I haven't had the problem running Brembo GT calipers up front now and Carbotech XP-12/XP-10 pads with Motul fluid. I think the added mass of the GT caliper helps, but we really do need additional cooling.
