Now the wild part.
That is an OEM Busa rotor!
Thats awsome! So when can I send you my fronts and rear to get done!
You don't want to do that with the front rotors, brakes are too much of a safety item to just modify this radically without engineering.
I wouldn't hesitate doing this to my rear, though, I only use it in low-speed, low-traction situations. That looks very cool and that's a big weight loss.
