Hi I have a 07 is250 AWD.
I'm currently dropped 2" on Bc coils with 19x8.5 +20 all around with 215/35/r19 tires.
I'm going to get new wheels and want an aggressive setup without going staggered. I'm thinking between vossen or Velgen wheels. Please help me. Also my car color is smokey granit 1G0.

 

I don't think either company make's their wheels in 18's. I've had a couple sets of 20's one set of 19's and currently on 18's.

It all comes down to preference and how low u are. My old IS I was on springs with 19's and 20's. My current IS I'm now running 18s. I got tired of the rubber band tire look and there really wasn't any 20s or 19s on the market I was interested in. But here's a few pics to give u an idea





19s





20s





18s

 

I have a set of wheels for sale!

damn really like those wish i lived in the states would sell my 20"s and take those from you...

 

Here are some images to help you visualize how Vossen wheels will look on your car. Looking at the drop you have, the 20" will sit perfectly.

Vossen CV4 - 20x9 / 20x10.5


Vossen CV3-R - 20x9 / 20x10.5


Vossen CV5 - 20x9 / 20x10.5


Vossen CV7 - 20x9 / 20x10.5

 

You do have a point, I hate rubber band wheels but I also want vossen wheels. Man this is hard

 

19” is a decent compromise between comfort and looks. I personally think 20” is too big looks-wise.
