I' got Vossen CV3 9x20 +38 and 10.5x20 +45 with Michelin Pilot Super Sport 245/35 and 275/30 with KW V3
Should I roll my fenders or this fitment will be ok?

 

and i wanna drop a little bit)

 

You'll have to shave the rear quarter panel for sure. BTW, your tire sizes are much taller compared to stock ones. You might want to keep the overall diameter as close as possible to the stock diameter so your speedometer reads correctly.

You will need to roll your fenders.

 

They are a bit taller than stock size, I'd def go smaller. Did you buy the tires already?

With a drop you'll need a roll for sure and like Rex said you might even need to shave

 

Yes. I' v already bought it. I cant ride 275/25 and 245/30 in case of bad road conditions(((

 

They got it right. Thanks! Can't wait to see your IS F!

 

i plan on getting the same thing except the tires sizes will be 245/30/20 for the fronts and 285/25/20 for the rears. not sure what tires to get. might just try the vredestein.

 

How about 245/35/20 or 245/30/20 and 285/30/20 ? CV3 also ? wil that be similar to stock height ? thanks

 

As others mentioned, those tire sizes are tall for 20's. Maybe you had confused those with 19" wheel sizes?

Anyway, the rear will need a roll / shave.

 

yes that is what u want stock but not with CV3, i think the recommended sizes are 240/30/20 and 285/25/20. the front will be a little bit taller on your setup and the rears too.

 

any recommended brand tire? i know a few that seems to be taller then other brands.

 

240 is very hard to find, so far i see hankook with 245/30/20 285/30/20 ... how bad would it be ?

 

This is what I have on the CV3's and you will still want to roll the rears but nothing excessive. I have Invo's and the shoulder is not as squared off as others so that actually helps as well.

 

Are you Low ? how low are you ride ? yeah i'm going to rolled my rear maybe not the front but if need too yeah.. nothing much i hope.
