ok, currently I have 19's racing hart rs451. Regard to the performance, I'm thinking to get the light weight rims and downsize to 18. what do you guys reckon? do you think those 18's AME rims will look really funny as 17's on our G? any thought? spec. 18x9 +20 18x10 +20
they look like 19's to me from the pics

 

18s look tiny on the G35, do you drive a Z or a G? Remember the Z is smaller so it looks better with 18s.

 

18's will give you better performance assuming they are the same weight or lighter than the 19's, and will ride better than the 19's.

 

Don't worry .
I'm also downgrading this summer to 18's from my
Racing Hart RS-721.

Was thinking of the AME FS01
Decided on the Work Emotion CR's 18x9.5 +20 offset all around

I have rocked 18's just fine.

Here are some pics of my car on 18's during autocross and winter:

 

Think about the looks guys....THE LOOKS!!

 

If I were to go down to 18's, it would not be in that style of rim. I would look for something with little to no lip and more of a "track" with more concavity. That way the car looks like its made for performance, and not stuck with half-assed 18" bling wheels

 

tires will be cheaper... i had to go back to stock 18's for now cuz i bent 2 of my racinghart J8's... anyone know where to get fixed..

 

I have to agree

 

I have 18'' SSR GT3 for sale... 24 lbs each son!

Thanks for the pics. They look a bit of tiny as fullvietFX said, but still look good tho.
