Wow, thanks for all of the collective wisdom from the many sources. I noted that the winning STF car this year was a 2008 2.3 Hatch, appeared to be on 16's or 17's.
I am still conflicted about perhaps starting out as HS/GS for the first year or so, get to know this car, and then move towards STF. I'm guessing that going from my '08 Hatch 2.3 to this '06 2.0 Sedan will offer some different handling adjustments. That and it's around 240# lighter too. :-)
Even if I do the HS/GS thing, I can run either the 15's or the 16 diameters given the new Street Tire allowances, so either way these are good data points we are sharing.
At 75mph on the highway, the difference in RPM will be about 8.7%, or around 300rpm. Speedo will say 81 ;-) I really like the 15's one inch lower stance, as our cars sit so high anyway. Leaning towards the 15's at this time.
Appreciate all this info, guys. This will be fun.
Oops, one more question. If I get the 7 inch or 7.5 inch wheels, what offset should that be to clear the 225x45x15 tires? I think I recall that stock offset is 52.5mm..? Tire Rack sells a 15x7 with a 45mm offset. Would that clear internally with the 25/15 tires?
