I ran ducts from my BRE like chin spoiler tie wrapped to the rotor dust shield. I found duct work really didn't have as much of an effect as good fluid, regularly changed. I assume your fluid was from a fresh container? I had similar issues until I went to Motul RBF600. No ad for them, but the stuff solved a bunch of my issues. I also had a brain adjustment with how I was using the brakes as well. Shorter period of time but harder on the pedal instead of longer easier.

After I read this thread I was a little nervous. I just bought set of Diamond 14x7 for my 240Z. When I talked with Bill he indicated that the larger stock car wheels use a 45degree, but any of the 13" or 14" wheels have the 60 degree seat for stock lug nuts. I'll have to look tonight when I get home. He indicated it was based on the wheel stud diameter in the wheel.
