Just got these in the mail today.
Z1 2 Piece front rotors.
Went with EBC yellowstuff for the pads.
I wanted to run out to the garage, crank up the stereo, and get to work installing everything so bad today but I have way too much studying to do
Additional Specs on these rotors that aren't listed on Z1:
Directional (48) vane venting
Appears to be manufactured by Brembo but designed and made for Z1 motorsports
