Somewhat separately, as much as I'm a 16" Fuchs, especially Fuchs Evo, fan boy / devotee, I think my '89 M491 "hot rod" build (eventually shooting for ~2,500 pounds & ~350 hp) is likely gonna need more rubber than my current 205 & 245 happy place. If I do Ruf 9&10 x 17 wheels, what are the recommended tire sizes? I'm not looking to cram the absolute largest tires possible under the fenders as I would A) prefer to avoid fitment issues and B) attempt to preserve some steering feel.
BTW, I know we've gone completely off the rails / this post's original topic.Such is life in the big (Pelican Parts forum) city.
Drove this Ruf wheel "laden" '89 930 last fall. It and it's wheels "left a mark."

The thing that determines s/r wrt the wheel is it's ET, higher numerical ET = lower s/r
a 911 w/ 7ET23.3 has a s/r of 52.4mm
a 930 w/ the 21mm spacer, whether from the o/s hub on late 930 or the 21mm spacer of early 930, has a s/r of 73.4mm
use a wider wheel like the early 911 Ruf 8s w/ ET 30 and the s/r goes down by the difference in Ets
the early Ruf 9 w/ ET17.7 would raise the s/r compared to a 7 ET23.3
RSR w/ the 21mm spacer and w/ 9ET3 has a s/r of 72.7mm
similarly track changes w/ ET changes, a 930 w/ 7ET23.3 wheels has a front track of 1432mm, 60mm wider than a 911 w/ the same wheel
the Ruf 8ET17.7 would reduce track by 35.4mm
