Hello,

If somebody has the same car as me and their wheel is 18x9.5 +35, and it looks perfect to me, what do I do if I got the same wheel but it's a 18x9 + 45?

If I got the same width with different offset: 18x9.5 + 45, i would just need to get 10mm spacer for it to look the same, right?

However, the width of my wheel is narrower, so how do I take that into account for the spacers? Do I add the difference in size in mm? so, .5 inches to mm = 12.7mm. 12.7 + 10, so about 23 inches would be how big of a spacer to match?

 

Just for your reference:
On my car, I have the luxury package wheels (same width & offset as F sport) and I am maxed out on the spacer size
18x8 +45 - 25mm spacer front
18x8.5 +50 - 20mm spacer rear

My point is that you definitely don't need a spacer that big, Sasnuke will definitely give you a better idea.

 

@Sasnuke help please! what do i do to calculate if my wheel width is different than the person's i'm imitating?

 

If the rim is 18x9 +45 and you want the fitment to look the same as 18x9.5 +35, then you need a 15mm spacer.
While the difference in width is 0.5 inches (12.7mm), you would divide that by 2, then add 10mm...so it would be 10mm + 6.35mm = 16.3mm.
Since you can't get a 16.3mm spacer, the closest size is 15mm.

 

Ah, thanks so much!!

 

oh, another question regarding spacers, is it better to get spacers without the studs on them and just get new longer studs, or are the spacers with studs just as strong?

 

I got H&R Trak spacers that had studs on them and I've gotten to pretty high speeds, hit severe potholes, nothing ever happened. I feel like this depends on the thickness of the spacer because once you put it on, your stock studs are too short to put the wheel on. I feel like anything above 10mm, you should get the spacers with the studs on them

 

For spacers above 10mm you would be getting ones with the studs in them.
H&R is most definitely a reputable brand.

 

But what if you got longer studs and replaced your stock studs? and then got spacers with no studs? that way it's just one long stud and a spacer instead of a stud, spacer, and another stud. wondering if one long stud would be more solid and safer.

 

In general I’d say the longer stud is going to be less safe, due to stress on the material. Using a hub-centric spacer will alleviate some of that stress, but only if your spacer fits snug on the lip of the hub and the wheel design fits snug on the lip of the spacer.

 

In the case of using longer studs, the fitment of the spacer becomes even more crucial.
In a normal setup, the hub of the vehicle is carrying the weight/load of the wheel, the nuts at there just as a clamping force to hold the wheel to the vehicle.
With the longer stud, if the spacer is not a perfect fit to the hub and the rim, then the stud would be carrying the load of the wheel, which is not what you want.
Also if you ever change wheels then you need to account for the longer studs and if a spacer is still going to be used.

For myself that has a winter and summer set of wheels, longer studs are not an option as they would be too long for the stock rims I use in winter.
Then I'd have to be into running open ended nuts to make sure they clamp properly, etc. etc. etc....it just becomes a hassle.

 

Have 2021+ model year spacers come out to the market yet? I've been searching but can't find anything.

 

No one makes spacers specific for your car and model year. You just need to know your bolt pattern, thread size, and hub size and buy spacers that match.

 

H&R has spacers that are 5x114.3(bolt pattern) and have a 60.1mm center hub for the Lexus UX that are 7mm.
Depending on how much of a spacer you wanted, those would work as far as I can tell.
As the 2021+ uses wheel bolts and not studs/nuts, you may or may not need longer bolts.

I guess it would help to know what you're looking for specifically...i.e. size of spacer

 

hi @Sasnuke , i'm about to order spacers for my 2015 IS350 FSport for Volk TE37 SL's.
before doing so can you just confirm these spacer specs will fit? i'm pretty sure 60.1 is the correct bore size from my googling.
