Although not my style of wheels they don't look bad. I personally wouldn't go beyond light weight 19s on my 99 GTP and 20s on my 05 Comp G (maybe). Just my personal preference.

As for the stick-on portholes... I'd lose them. Non-functional, wrong make of car for them, and $$$ that could have gone elsewhere.

I am probably the top defender of personalization, so keep making it yours!
