ok so i cracked open my new sixport TURBO keg anyway, i noticed that the faces seemed deeper than my old s4 n/a rotors, i measured them and they are appox. 3/8 in. deep. i wanna make sure because the engine was obviously rebuilt and messed with. also! there were some numbers/letters maybe, stamped in the primary ports where the lim bolts up. i never noticed that before, does it mean anything or?

 

????

 

ok the 87-88 turbo rotors are about 1/2" deep, the 86-88 na rotors are about 1/4" deep

 

Nick, bring one by, Ive got piles of stuff to compare to. Also, Hook me up with a rear na plate
