Could the rims had really affect your driving experience? Base spec 16" to high spec 18" is quite a big jump

huge different on 3 perspective
1) larger wheel, thinner side wall the turn-in would be sharper, less delay. This can be reduced by getting a higher performance, stiffer side wall tyres.
I think most people should be able to feel Michelin XM vs PS4S, it is super obvious.
But if you can't tell the different of eg:. Continental SC7 vs Michelin PS4S or not so high end MC6 vs Primacy4... same category different brand then this turn-in sharpness feel maybe irrelevant to you.
2) Depends on the TOTAL weight different, and the weight distribution (middle of the wheel vs outer edge close to the edge). The acceleration + bump characteristic change.
I must emphasize TOTAL -> complete wheel -> rim + tyre. My experience is 5kg lighter per wheel, so it is super obvious.
Most claim they call fell 2kg per wheel difference, I would trust that. Those that claim 1lbs (0.5) like day and night, I think it totally BS.
The initial acceleration + braking response is sharper, more immediate.
But when the car is in constant acceleration, not much difference. The key is sudden pace change.
Like you accelerate mild, then sudden accelerate more, or light tap on the brake then back to throttle etc. The whole car response faster.
In racing, little edge on the time attack, but very useful on dog fight. On the road don't expect magic on 0-100km/h, it is more on the feel.
After 2 weeks, when I totally got used it, the magic sensation gone. Until maybe I drive a friend's car of same model...
3) Comfort/Bump. Lighter wheel, the big bump in less intrusive to the cabin. However the small rattle that wasn't present on heavier wheel can be felt on lighter wheel.
Then generally smaller wheel, thicker side wall tyres can absorb the small rattler better than low profile tyres.
The final effect have to see complete wheel package => Complete weight, rim weight distribution of the spoke design, tyre side wall thickness, tyre side wall stiffness, tyre width.
Probably best way is test drive see what you like.
