Erm, don't know, but I do know that most brake master cylinders are either 3/4 inch or 1 inch in diameter. Nissan use 3/4, so should give same feel as any aftermarket racing set up.
I have a 4 pot set to go on the rears, and for now I have fitted a Tilton brake bias adjuster on the rear line. Once the new cage is in, I will be converting to a Tilton brake pedal set, with double cylinders and brake bias bar.
Will post up on how they feel, or any problems on the bias side.
