Hey Guys,

I'm kinda new to this but i'm thinking about putting some TIG T08 19 inch wheels on my car

front
19 X 8.5
245-35-19
40mm offset

rear
19 X 9.5
275-35-19
40mm offset or something close to that....

this is what the guys at California Wheels have recommended and i was wondering what you guys thought of it... i mean from everything i've read the offset seems really high... ohh yeah and the rear fenders have been recommended to be rolled in case i go over a bump and pull the fender down.... I was hoping you guys have some good advice whether to pull the triffer on this or not.

THanks

Offsets are about 20mm too high for a Z.

Not really feeling the style of those either.


My advice - consult one of the reputable vendors on this site (go to the marketplace and browse posts in the vendor classifieds - wheels/tires section) for options based on your budget instead.

California Wheels does not seem to have much 350z knowledge/experience.

Those offsets are horrible for a Z. You need to get something in the low 20's range.

that's what i thought and i wanted to ask you guys first... is offset something that you can change or is that part of the wheel itself
what is the downside of having the wrong offset and how do you fix it?

The wheels will be sunk in. You could buy spacers to push them out farther but it would be wise to simply buy the right offset from the beginning. Check out the vendor classifieds and look into some Rota's.

those are terrible rims and terrible offsets.

and offset 'can' be modified with spacers, but 20mm is ridiculous, and in some wheel designs it affects the face of the rim, or the size of the lip.

+22 is the standard offset for a Z, higher is considered aggressive , and lower is tucked. and this is on a 8.5-9.5 front (9.5 preferred by most) and 10-11 rear (10.5 preferred by most)

Can a wheel with a 2-3" lip have an offset of 32-35 and sit just as flush as a wheel with minimal lip and 20-22 offset? Basically, does the depth of the lip account for different offsets?

it all depends on the wheel, honestly. but generally no.

you might be misunderstand what offset is, or I am misreading your statement but: the wheels cannot stick out the same amount if they have different offsets (and the same width, etc). the offset is what determines how far out from the hub the wheel sits. think of the offset as the barrel of the rim sliding in and out from the hub mounting point. a lower offset has more rim on the outside of the hub, and a positive offset has more on the inside.

now in terms of the size of the lip, that is dependant on how the rim is made. 2 pc wheels almost always have different sized lips (and is why you see guys going to really crazy offsets to maximize the lip), while some cheaper 1 pc rims make up the offset by increasing the material on the back of the hub mounting point to push the wheel our, or bring it in, and others adjust the angle of the spokes (concavity determined by offset, another reason people get crazy offsets).

I hope that answers every question you were going to ask.

oh wait, stock offset is +30, so judge from that what YOU think you should pick as offsets i.e. nothing higher (+40, etc) than that and preferably much lower (+22, etc)

Thanks for the info motormouth. I've read about offsets before and thought I understood it pretty well, but my buddy just ordered some wheels and that's when I got confused.

He currently has some cheap ADR's that are 19x8.5F and 19x9.5R. I assume they are both +35 cause that's all I can find anywhere online. They look fine on the car, but I'm not sure if he has spacers or not. He bought some other cheap wheels, the Stern ST-7 in the same sizes, with +32F and +35R. Seller assured him that they were correct offsets, so that's why I thought the lip sizes were a big factor.

Motor knows his offsets fer real. Excellent answers. I would run
screaming from anything greater than +24.

those cheapie wheels are ok, but you can look at most of them and see the quality is lacking.
