i've been trying to understand how offsets work, and i understand it for the most part but given that our cars have a limited offset we can work w/, would

19x8.5 +40
19x9.5 +40

work? and if anybody is feeling generous, how would that look compared to a wheel that would have +50 rear offset?

lets assume the wheels are cast (yes, i know) w/ a concave look...more concave or less?

thank you!

AFAIK
The biggest problem is with the rear
Example: +54 (stock, I think) will be closer to the body of the car while +40 will bet further away. Meaning +40 will stick out more.
But again it depends on the tires you will be using

i was hoping to run 245 series in the front, and 275/30s rear...

thanks guys

Your rears would be a problem. I stuck my w203 Brabus reps that are 19 x 9.5 et41 with 265/30/19 rubber and it stuck out to the point where it would rub and probably distort the quarter panel if you were driving and hit a dip. Not a good thing.

The lower the offset number, the further is sticks outwards away from the car body.

19X9.5 40 OFFSET will not work with a 275 tyre.
I have 19x9.5 50 offset with a 275 and it fits with no rubbing but is very close to outer guard.
40 offset will stick out too far.
You have to watch wheel design also to make sure they clear brake calipers.

so it seems that going 19x9.5 +50 is the best bet.......

any difference because these are cast wheels (as opposed to forged) that im looking at?

since the thread is about offset....
planning to order forgestar f14 19" rims for my c63...but i want the rims to be flush with the body.....what is the best fitment with Yokohama neova AD08 Tires?

tire size planning to use is
front 235/35/19
rear 265/30/19

rim size planning to purchase
front 19x 8.5
rear 19x 9.0

Anyone know which offset i should order for those rims?

So is a 18 x 9.5 ET 60 the same fitment as the oem stock 18 x 9 ET 54, for example?

i dont know if youve seen this thread or not, but i think this might help you out..these wheels look great here...plug and play

I find it interest how all the people on this forum seem to compensate for lack of traction with more and more tyre width.

I personally would drop offset to push the wheel out the guard. Then lip the rear guard (push the inner edge upwards) to make more space or even flare it out a bit. Then instead of running a 275 on a 9.5, run a 245/40 with some stretch but an awesome quality tyre (even a semi slick)

That would be the way to go about it if you want to improve looks but maintain/gain traction.

Unbreakable1

bringing this back up...

question related to the lip...im assuming that a 19x10 wheel vs a 19x9.5 will have a slightly greater depth given the same offset and i know a few people here are running 19x10, but does the offset remain +50 (as it would be w/ 19x9.5), or would i have to go a little higher given the increased width?

I have 20x10 on my rears...with offset 51

Unbreakable1

so assuming you have a lip on it, how would the depth of the lip differ with a 20x9.5 offset 50 wheel?

Jae Duk

I'm not sure how "deep" the lip is on mine. Haven't put them on yet, they're at the shop waiting for me. But I was told that I got up to 3" lip. With 9.5" I think you can get close to 3" or at least 2.5" if I got 3" on mine. But don't get concave rims, you will not get that much concavity with our offsets.

Unbreakable1

i think im gonna go 19x10 and a similar offset...i was thinking 20s, but im fairly particular about ride quality so i think i will stick to 19s

and yea, the wheels i spec'd up top arent going to work so i found something else

what kind of wheels did you go w/?

Best tool that I have seen so far..

Venaci...they're made by Works. Got too good of a pricing to pass up on. Design is exactly like the Work Gnosis GS4.

BTW, where in socal are you?

Unbreakable1

oh nice...im most likely gonna be placing an order for some Work wheels too soon, hopefully this week

im in Claremont, right under Mt Baldy

Jae Duk

Is that in SD area? If it is, sorry...I'm only in SD for school

Unbreakable1

haha...there is actually Clairmont around SD, but no, Claremont is 100 miles north of SD

what school/program? i have friends in SD so i do venture down there every now and again

If I remember correctly the forgestar rear wheels are 19X10 with a +45 offset, versus 54mm for stock.

Compared to stock: with the offset and extra width, you're looking at wheels sticking out 21.5mm or 0.86" more than the stock wheels. It's not that huge but it will not allow you to drop the car much. The reason the offset is higher is to leave some room for the wider wheels on the inside.
