I fixed my 350Z by removing the Yaw-sensor that controls the VDC...then all my braking issues went away. Mainly the hard pedal and the inside corner brake overheating (VDC was trying to straighten the car out of a slide)...all these occurred during full-on track seasons with OEM Brembos and Carbotech XP10 F & R, Hoosier R6 tires...
Not sure if this can be done on a 370Z, But I would assume so...
