Hi guys... I'm planning to buy a set of F14's with the following sizing and I want to know if it will be too aggressive.

F:19x9 +25 (245/35) [semi concave]
R:19x10 +30 (275/30) [deep concave]

I have an 07 G35 Sedan journey w/ eibach pro kit.

Thanks.

 

Here's a good calculator, used it recently and ended up w/ perfect offsets for my application~

FWIW I went 8.5"x20" +40 245/35/20 fronts (tires about 10mm from fender lip since front fenders have less clearance underneath)
10"x20" +45 295/30/20 rears tires about 3mm from fender roll
lowered on coilovers, no gap.
I think you'll need slightly more conservative offsets, might be poking a bit w/ those that you listed.

 

I think the rears will be poking slightly. We had a sedan running our 19x10 +25 V710s all around with 235s and the wheels were poking out past the fenders.

 

FWIW, my old wheels, pictured below, will stick out 1mm more than your rear set. These are with 285s.





Roughtly -2 camber with an Eibach-ish drop.

 

Actually in my opinion those are pretty good flush fitment for the sedan. The front I can guarantee you will be okay. Here are some pictures with the OEM 370z Ray wheels. This guy is running the almost the exact same setup you are looking for except his tires are a bit fatter and the fronts are 5mm more agressive. I say if you at least have an eibach drop like this guy, it will be sitting perfect.

I say go for it if you are getting a good deal. Post pics up when you are done!

 

Looks like a good offset and that sedan looks really good!
