PS13 rotors are 11 inch. I've ran them hard through patterson road, as well as primus repeatedly, and other sudden 120-45 stops (hint oh shit a cop!)

I've never faded them with my setup. (150whp 160tq KA24DE)
I run the stainless lines all around, super blue brake fluid (www.splparts.com), ceramic brake pads, power slot slotted rotors (thank you regina!) and metal master pads in the back with stock rotors. I also have a new brake master cylinder(HS13).

Regina and I both have them on our cars, and we love the feel.
Epstein, you've driven my wolverine car with it's brake setup, what did you think vs your z32 brakes ?
