Question Minimum Rotor Thinkness (Genuine LR)

Question pertaining to a my 95' NAS D90
What is the minimum rotor thickness for Genuine LR rotors, both front and rear. The shop manual states minimum pad thickness to be .125" (3mm), but nothing about minimum rotor thickness.

According to Rave, "reclaiming" (machining) the discs the minimum thickness allowed to take them down to is:

Front discs: 12mm (0.47") solid discs

22mm (0.90") Vented

Rears 12mm,

Although the discs should have the minimum thickness stamped on them.... looking through the workshop manual (strange that this figure isn't give in Rave), it states:

Wear limit..

90: 0.38mm (0.015")
110/130: 1mm (0.04")

Per side of disc, so presumably you're supposed to scribe a perfect line around the circumference when the disc is new, then measure outwards from each side! or just double up the allowed wear and take that away from the allowed reclaimed thickness....which will give the absolute minimum allowed (reclaimed thickness minu wear)

therefore.... 90 is allowed 0.76mm wear (0.38 x 2 = 0.76mm off of a reclaimed 12mm solid - 0.76 = 11.24mm minimum, or 22mm - 0.76 = 21.24mm minimum vented

110 is allowed 1mm wear, so off of a reclaimed 12mm disc, that takes it down to 10mm minimum

Clear as mud eh???
