I bought some new Fuchs Felge 9x16 wheels for the rear a few years ago but haven't installed them yet. I intend to use the 245/45 tires with them. Bill- Didn't you say that alters the balance just enough to be less to your liking than the 8x16 in the rear? I'm much more of a street driver than a track driver these days. Any other comments about the 9J rear wheels? Thanks

I like a little less understeer than a stock, 7 205/55 and 9 245/45, while better than 7 205/55 and 8 245/45 still induces more understeer than stock. At least w/ 7 & 9 there is less defection of the tire thus better precision.
If using 7 & 9, 225/45 front helps balance the 245/45 on a 9, if 225/45 was on an 8 even better but there are no Fuch 8s that work well in front.
If you want to optimize an SC/ Carrera using 16s then aftermarket 8ET27 and 9ET12 w/ 225/45 and 245/45, any smaller wheel compromises one aspect or another.
That's why I like 205/50 on 7 and 225/45 on 8 so much, there are no compromises to handling balance or precision and you get the additional benefit of livelier performance.
Yes 7 & 8 w/ stock sized 205/55 and 225/50 is a step up from those same tires on 6 & 7 because of the increased precision you get.
combine that w/ the added grip from new supple and sticky rubber it's like night and day.
Of course 7 205/50(not 205/55) and 245/45 isn't bad, it's just not optimized, The nicest feature over 225/50 is the shorter tire height which noticeably adds to acceleration, just not as well as 225/45 on 8s
