Two ideas and I will give you as much info as I can remember.
#1 My good buddy used to run 7 inch phone dials from a 944 with big spacers and longer wheel studs on a stock bodied 914-6 front and rear with 205s
#2 I ran 7 inch Fuchs early 911 rear offset on the rear of my 914-6 with 225s and stock body work.
Also ran my 914-6 with 6 inch Fuchs 911 offset front and rear with 205s under stock body work.
Lots of combinations out there.
Remember that there is such a large variation in body fitment on 914s that what will work on one car won't on another. I had a 70 1.7 years ago with 5.5 fuchs that fit great with 205s, took them off and put them on my 74 2.0 and had to use spacers in the rear...so you never know. ( rubbed on the inside of body work not on fender lips)
