10.5 +30 will fit fine with around 2.3* of camber. 275/30/20's will fit fine on those with a light stretch depending on the tires you get.

Ah ok then, well you're just gonna have to run a bit more camber to fit them and they'll be fine.
Waiting for the pics.

I'm planning on getting the Vossen vvs082 in 20x9f and 20x10.5r. The offsets Vossen offer for our car is 38f and 45r which is already pretty flush from the pics that I've seen. They offer 25f and 30r for the 350z, which what I want to try running, but still unsure. With the lower offsets, I'm sure I can get a little poke, but just concerned with the amount of camber I would have to run. I don't want to be replacing tires sooner than needed.

What setup are you going for?

Hey Borna, thanks for the advice. Could you teach me how you got 2.3* of camber? With this amount of camber, how would the tire wear be?

i have the 082s wit the 38 and 45 offsets. they sit flush. running 245/35 285/30

^You're pics are one of the ones I used for reference. Any rubbing with the 285's? Did you ever get a shot of the fronts straight on?

Here's the best I could find beezy

Thanks for the pic. Thats pretty flush. I think with the +25f and +30r I could get a little more poke or just stick with that setup.

i rubbed slightlyy but only when i take a turn going fast. thats about it

edit. that scrawny *** kid isnt me in that pic lol

How soon you getting your setup, denishot?

No problem.

I honestly don't have a formula for calculating camber, I just estimate it through past experiences with different fitments. The more you get into aggressive wheel fitment, the easier it'll be to estimate camber. More accurate too.

With 2.3* of camber your tire wear won't be too bad. I'd say you'll get around 13k miles with normal driving on Falken FK452's and then you can just flip the tires and get another 8-9k out of them. Around 20k miles isn't bad at all for aggressive fitments like what you want.
Just make sure you dial the toe back to spec cause toe is what really eats up tires.

Thanks again Borna. I'm dropped on eibach prokits, could I achieve that camber naturally or will I need a camber kit to dial in more negative camber?

I think you'll need a camber kit.

The Eibach's give you about 1.7* in the rear without naturally.

The H&R's give you around 1.8* and they can be adjusted without a camber kit to around 2.0* so the Eibach should only adjust up to 1.9-2.0*

IMO, you should get the wheels first and try your luck and if you can't adjust them enough naturally then just order up the camber kit. It won't take long to get delivery of them anyways since you live in SD. I tend to get my orders within a day or 2 depending on where I ordered from when I'm in SD.

Cool thanks again. I already have the camber kits, but just never put them on.
