Just a few quick photos of the front rotors to show the differences between each. Quick notes are:
1. Zimmerman non-drilled
2. Different venting on all three
3. Different cross drilling on OEM vs. Lambo (15 rows of cross drilled holes on Lambo and 14 on OEM. Also a lot of the cross drilled holes on the Lambo rotors are in fact solid and not drilled)
4. Different amount of isolation pins on Lambo vs. Zimmerman and OEM (14 on the OEM & Zimmerman and 15 on the Lambo)
5. Different hubs on the back of the Lambos
