Looking for fitment specs for wheels for a 2018. going to lower it but not much...... maybe bag it haven't decided.
not sure what the best size would be pics and sizes would be awesome
I Know I want 18s was thinking 18x9+35 or 18x8.5+30 or something in that range

 

18s too small

 

Just for comparison, here's my son's '17 ILX with aftermarket 17x8 wheels with the stock Michelin tires. Not lowered.

 

basically it's a personal decision. the two people that answered gave you completely different advice.
if you know you want 18x8.5-9inches, go with what you want.
interested in seeing what you end up with

 

Definitely not. This is an ILX, not a RL(X). 18s are probably the most common aftermarket wheel size for these cars. Go post whore somewhere else.
