I don't think they look bad at all bro. The main thing is that you are pleased with how they look. Also on what you're going for, looks or performance. Bigger wheels wont make too big of a difference but just slightly. I always here the term RICE and blah blah blah. I myself have a set of 18 inch hyperblack wheels on my GSR for show and a set of JDM 15 inch gunmetal Buddy Club racing wheels. I currently don't have a pic of the 18's on my car but it looks real nice. For performance they can't compare to the 11lb Buddy Club wheels and the sticky Azenis tires. But yeah don't fix your car up to please others. Do what you like.
