I've done the search on wheel fitment and offset and had a hard time finding the answers I'm looking for.
I'm ready to buy wheels, staying stock at 17" but I have questions concerning offset.
First, what is the width of stock CLS wheels, 7 or 7.5?
Second, what is the offset of a CLS stock wheel?
If I buy a wheel that is 17 x 7 with a 48 offset, will it stick out further than my stock set-up or less?
Basically, I want to have the wheels look the way they do stock from a stance standpoint. I could live with a slightly wider profile but not too much.
So, what offset in a 17 x 7 or 17 x 7.5 would I need to stay close to the stock profile I have now.
I have Comptech springs as well.
Thanks!

Stock CLS rims are 17X7

Stock offset for CLS rims are +55

You can use offsets from +42 - +55

If you got a 17X7 rims with a +48 the rim will stick out just slightly. The lower you go the father it sticks out.

For comparison I have 17X8 +48 & the rim looks almost stock as far as stance goes.

Exactly the answer I was looking for, Thanks.

So then an 18"x7.5 say... the best possible offset would be close to what +49 to +51 or something... I know nothing of this and havent looked into it yet. But with tax return $$ comming , now is a perfect time to learn.

Is there some kinda reference chart someplace or can someone gimme the Cliffs Notes explaination ?

hmmm, what they say above is the most ideal. However, i bought 18x7.5 rims with +42 offset, dropped on H&R Sports and i have no rubbing issues whatsoever...even with 4 ppl in the car...

This thread here should help you out...ppl list type of rim/ type of drop/ offset and rubbing issues....

The brand and series tires you put on are what make the difference between rubbing and not rubbing (most times). That's often times why you hear two people with "the same setup" saying one person rubs and the other doesn't.

Right. But I had 18X7.5 +42 with 235 tires & rubbed. So it's a toss up with a +42. Some cars it works, some don't.

yeah mine rubs a little with a 18 42 offset with tein ss's droped all the way

mine are 225/40's...that prolly the difference...

ok so looking at the thread from A-TL plus other info here...

2.75" Drop on GroundControl Coils with stock rims dont rub a bit

New Rims:
18" x 7.5 +48 or +50 offset would put me at stock stance most likely still not rubbing is this correct?

Ideal fitment for a 17x7.5 is around +51 to +52.

Warning red area == math crud


Just start with the stock wheel width of 7". Subtract this from the new wheel width of 7.5", then divide by 2.

(7.5 - 7.0)/2 = 0.5 / 2 = .25"

The wheel would stick out 1/4" more if the offset was identical to the original wheel. (The inside would also "stick-in" by the same 1/4" distance IF the offset wasn't changed from stock.)

Convert to mm: 25.4mm/in * 0.25in = 6.35 mm

Stock rim is +55. To move the rim inward, a higher offset is needed.

+55 + 6.35 = +61.35.


So, if you want the outside to line up perfectly when you move to a 7.5" rim, you would want to have an offset of +61.

Forget about finding or making a rim with this offset. You really want to keep the center track near the stock value, and that's related to offset. IOW, you want to stay as close as you can to +55 without rubbing.

The +42 is not a very good chose for you (you did want something that didn't stick out far). The 7.5 x +42 will stick out about 3/4s of an inch.


HRE recommended at +51 - +52 offset as the "perfect" offset for a set of custom 3-piece wheels. The 17 x 7.5 worked perfectly with 235/45-17 on a Comptech lowered car. No rubbing ever.


If you want an easy way to figure out what is going on, just use the following link and use 7 and +55 for the current wheel width and current wheel offset.

Will these fit?
18x8 42mm 73mm/bore

I'm guessing it depends on tires, huh?

Thanks.

+42 would not be my first choice...

And, if you're lowered, I think you would be looking at potential rub problems. (I know someone will come along and tell you they aren't rubbing ... YMMV)

I don't think so. Even with 225 tires that's an 8" wide rim! If your not lowered you might be able to squeek by.

BTW- I have to make a correction I'm running 17X8 +50 offset.
