Has anyone crammed an 18x11 or 19x11 on the front and back of a base RWD G37? What offsets did you go with?

Did some searching and didn't come up with anything.

 

I have 19x11" wheels front and back on my xS coupe. They're et25. They poke a bit in the front because I needed 5mm spacers to clear the calipers. They are sucked in in the rear at the moment, but I also have GKTech rear drop knuckles which pull wheels in more than stock.
I removed all my fender liners, and trimmed the rear bumper tabs, but didn't have to roll, or otherwise modify my fenders. Without the drop knuckles, the rears at et25 will poke slightly less than the fronts. If I were buying custom wheels, I'd go with et27 up front, assuming the wheel would clear the caliper, and et15 for the rear with drop knuckles.

 

Thank you! That is great information. If you have any pics, I'd appreciate you posting them up.

 

I don't think I've posted any pics since the drop knuckle install. I'll take some when I can and post them up here.

 

11" for the most part is pretty wide for offsets lower than +30. Aodhan and Varrstoen are pretty popular brands that make wheels in a 19x11 +22 so you will find more references for these wheels than others.

Most running 11" +22 or lower are generally bagged, and the setup requires negative camber and some stretched tires.

If you find a 11" say in a +40 offset, you can fit a 275 or 285 in the rear. It might not work in the front as it may contact the suspension.

Here is an example.

I plan on racing autocross, a few events i have lined up are pretty much run what ya brung, so I'll have adjustable suspension and am trying to get a 305 front and rear with a 200 treadwear. That's pretty much necessary for me to be competitive.

 

Here's a quick and (very) dirty pic of my coupe as she sits. I still need to add the rear extended lugs and 10mm spacers, and lower the rear a bit more to make the fender to tire gap even front to back. These are Aodhan 19x11 et22 with 275/35s all around.

 

I could easily fit 305s in the rear of mine right now. the problem would be the fronts. 275/35s are already getting close, and I'm pretty sure i can't do 305s in the front at this height.

 

I'm going to 3d print a wheel fitment tool and do some messing around. I'll post up what I figure out.

 

Alright, I'm closer to making up my mind. I'm going to go with a custom forged wheel so I want to make sure I nail my offsets.

Front -
I took my rear wheel, 285/30R20, 20 x 10 ET30 and it fit with a tiny poke.
I think 18" x 10" ET27 and running a 285/30R18 wheel would be perfect. Thank you @digital.aaron , I think you're spot on with the ET27 suggestion.

Rear-
As above, my current rear wheel is 285/30R20, 20 x 10 ET30 and it sits pretty close to flush.
This is where I'm less confident.
I'm thinking 19" x 11" wide ET 25.
The current rear wheel has about 2 inches of clearance from the shock. New setup would be .8" wider and .2" (5mm) further tucked in, so I *should* have the clearance needed.

Any more opinions would be greatly appreciated and thank you everyone for your input so far.

 

The 19x11 +25 will poke without camber.

Here is a reference with the 370z nismo rear 10.5" +23 with 275/35, you can see it already pokes.

11.0" +25 will push out 4mm more than the 10.5" +23, and you are wanting to use a wider tire of 285.

Pics of how the current 285/30R20 fits. And proof of LS swap.

 

I put the wrong offset, I should have said +35. I think that will land me where I should be.

Looks perfect, Pretty sure a 305/30 would fit

Again, way too much poke

And again, Looks perfect, Pretty sure a 305/30 would fit

 

The offset on the 19x11 and 19x11.5 will be very crucial.

generally to fit wider tires, the wider the wheel, the higher the offset you need to go to compensate for the poke, to be able to use without negative camber
