BBS Wheel Custom Codes?

[LUFTKUL]

I have some wide BBS wheels I'm trying to find some info. on. These were on an early 80's 930 used on the track with slicks during the 90's.

I'm trying to find out if these were custom made with BBS imprinting the owners name in them or was that done later by the owner as a "watermark" to prevent theft?

Is the 35/93 mark the 35th week of 1993?

17X11 rears (I think) not sure if the code tells me something. 315/35-17 tires

16X8s or 9s front. 245/45-16 tires

I have 3 rears and 3 fronts.

I know this isn't the what's the value section, but are these desirable?

Was running 16s in the front and 17s in the rear a popular option? I don't see this done often today.
