I will try my best to give a detailed description, here goes:
The steering feel becomes little heavier on the 18" due to weight of the rims. Ride is firmer with low profile tires & tire noise become more apparent due to the bigger tire grooves, FC is still very good for this long distance journey, I averaged 6.8L/100KM for the journey from PJ to Tuas, I drive mostly at 110km/h with auto cruise on, as mentioned earlier I did speed for few times over 160km/h to over take large numbers of cars

also to test the car performance at that speed, at 160km/h no apparent vibration to steering or to the car or any floating feel. So give you the confidence in handling at those high speed.
Do note that I have installed UR bars on the front, back and bottom of my car so it helps when cornering & stability. Cornering becomes more accurate and stable, very much less body roll than before.
After changing to 18" with tires 225/40/18 no touching of wheel arches or spring bottoming experienced even going over a bump as there is enough clearance. Everything feels like stock setup except the noticeable increase in road noise and firmer ride. I dont mind this for a better handling and driving experience.
The point about absorber "nyek" sound, its still there in the morning hump but much milder/softer now maybe I am taking the humps slower due to my new rims.
Hope its good enough

Sothys, now that you had traveled far outstation on 18" diameter n 8" wide rims, please relate us on your journey. Firmer ride? FC changes if noticeable? More stable when taking corners? No more nyek sounds from absorbers? Any of springs bottoming or tyres touching the wheel arches?
You are definitely capable of wonderful write-ups on your experiences with those nice rims.
Thanks Bro!
