My comment from 16 to 18 is more along the affects of handling. Yes the car will be fine with both but reducing the sidewall that much pending tire comparison of the two tires the 18 will show certain imperfections in road but have crisper response vs the cushion the side wall on a 16 will give. Keeping in mind tire selection is a major factor. A 225/45/17 in say a continental oem run flat will be more forgiving than say a 235/40/17 falken azenis 615k+. I use those as examples because I’ve run those on 17s with mine prior to 18x9 255/35 square with Toyo r1r. The particular car in question with the OP is non sport 2.5 prefacelift so ride height is higher and on non sport springs, putting on oem 18s will still have more wheel gap than sport trim and will be softer than on sport. Also 16x7 vs 17x8, 18x8/9 you’re naturally gaining grip as well when comparing oem plus sizes.
Yes this is my build sheet. Didnt even option the autotrans. Its base model. I will be changing the suspension to bilstein b12s or its coil over setup soon. I just wonder if i will gain more grip with high performance 16 inch tires. I have Apex wheels that I can put on the car. 17x9 square and 18x9 18x8.5 staggered. Both Arc 8s
