Brian,
I am getting ready to do my 85S pan gasket and MM's. I plan on some track days with a local club. Can you elaborate on a few things? I have an 80 pan. Is this the correct pan? What other parts? Where do you buy the spacer? Thanks.

couple thoughts.....a lightweight "track" (or race) 928 is LOTS of fun to drive.....much more fun than a full street car..... The 85 is not a bad car to start with, 32V that will make PLENTY of power, but with the better Borq warner gearbox.... The downsides are the brakes.....but if you are new to driving on track, the "S" brake isn't that bad....I raced in lemons for YEARS on S brakes...just with steel braided lines and Raybestos ST43 pads.....pad life was around 25-50 hours on track with excellent feel and rotors last for two sets of pads....Sure S4 or GTS are "better" but it takes an advanced driver pushing really hard to cook S brakes.....we drove the 2800lb estate for 8 hours per day, ZERO brake fade...none...granted it was only 215whp, but even on slicks I never-ever faded the brakes...in lemons trim on street tires it was almost too much...too easy to lock up!!!
The 1st thing is change the oil pan......125 hours on track on the Estate engine with only OB oil pan and 3/8 spacer....still perfect oil tests, no indication of bearing wear.... 25 hours on my current racer same story and neither one have oil coolers!!!!!!! I am also a big believer in shifting at 6000max
The E36 M3 is a great platform....I race against some of the best prepped E36 in the country, they are EXTREMELY fast...mostly due to the high level of top notch parts available for them.....but I still prefer my more rare 928.....the V8 sound alone counts for something....
If you want a unique car that is fast and fun to drive on track, the 928 is a good choice..... Especially for DE as you learn.........once making the jump to serious racing, it is harder to find a "good" class for the 928....but can be done with the right application of $$$$$.....

I believe Porsche stopped using OB pan (plastic cloverleak insert with mesh screen) around 1982 in USA cars...they are very easy to spot...what is your dipstick...if its yellow plastic than its the crappy later version...if its metal and much shorter than its the OB pan
Talk to Greg Brown of Precision motorwerks for a pan spacer...you also will need a mini starter, since the full size starter won't clear
