19x10.5 +22 in the Back (305x30x19 tires)

According to my calculations this should roughly give me 1-2mm more clearance on the inside and roughly 13-14mm extension towards the fender. The height on all for corners will be a tiny bit less than stock. I feel this will give a solid and proportioned upgrade from stock and with the right suspension setup will give it a great flush/slightly tucked look.

However, I have a couple of concerns...I see alot of 9.5 fronts ending up with a +22 offset, isn’t that over kill? How will that improve/change the handling characteristics of the car? Wouldn’t that square off all four corners rather than the back wheels having a wider stance (think Porsche)?

My goal is to have an aggressive street setup that I can basically take to the track with little to no modifications. It’s not entirely about the looks; I want to genuinely improve the handling with these mods.

what about 19x10.5 +22 offset in-front? will it fit the brake front caliper's?

Unfortunately when it comes to cars you usually have to sacrafice performance in one area to gain in another. The lower the offset, the farther the wheel and tire sit from the hub. This will affect caster and camber gain on the front wheels when turning which can lead to a number of handling problems. Now, that being said, most people aren't going to be able to notice the difference between a +22 offset wheel and a +40 offset wheel, but it does make changes to your car's handling characteristics.

So you have to decide weather you want to sacrafice a little bit of handling for a better look, or the other way around. Its not going to be a huge sacrafice either way in this particular case though, but your theory is on point.

:iagree:
honestly I'm would sacrifice a little for the looks.
why? because the z is a daily>track car to me.
I'll track it but honestly how often will you track?
this is another reason why I have atleast 2 set of rims for my ITR.
i.e. I use 17 inches daily, but when i track I'm using 15's/16's.
Also I'd redo my coilover and camber settings then realignment.
