does anyone know what the minimum thicknesses are for the front and rear disc rotors???

Front Standard thinkness = 32mm
Front Minimum thickness = 30mm

Rear Standard thickness = 12mm
Rear Minimum thickness = 10.5mm

thanks for the details. i probably need to replace my rotors as the interior sides of a few of the rotors are severely grooved but wanted to be sure.

anyway, thanks phml and everyone else on this forum!! this is such a great resource for lexus enthusiasts!

should be marked on the sides of the rotor , those specs are for OEM ones.
