1999 328i conv? Does anyone know off the top of their head what other models? THanks

Knowing the offset might help.....for OEM 18's the offset is 47mm Front & 26mm Rear.

the rear M3 wheels do not fit the e46 standard 3 series. however 4 M3 front wheels will fit.

The 18" OEM ZHP rims will fit on your 99 328i convertible.
The rims are staggered with 8" in front and 8.5" in rear.

For a picture of these rims, go to google and search "BMW ZHP" you'll see a bunch of example E46 3 series with these rims.

I just traded in my 99 323i sedan for an 01 M3 however I did keep my ZHP rims and are now for sale. The E46 323i does have the same offset as your 99 E36 328i converible. If your interested, I can sell them to you and include shipping for the cost for $1000? Also on these rims are Yokohoma AVS ES100 Summer tires with ~4K miles on them plus I have an extra set of front tires I had purchased as insurance which I will throw in with theset. All items are in good condition, rims have a few curb rashes but nothing signficant. I love these rims, they made dramatic difference to the appearance of my car. People wouldn't believe me that it was 99 model. If interested, call me on my cell 773-575-9043 (Albert from Chicago)
