Wheel/size/offset and tire/size/profile...can be confusing.

[YOWStinger]

Yeah man that’s it. Yours is pretty close. Are you using spacers?

No spacers, lots of options for off the shelf and custom 10.5+45, a couple of off the shelf options for 11+50 in 20”

How does this combo sound? Blaque Diamond BD-F18s at stock ride height (for now) in:

Front: 20x9 +35 with 245/35/20
Rear: 20x10 +40 with 275/30/20

 

[Hockster]

285's a re probably closer in diameter to the 245's for the front.

My current set up @ stock height:
Wheels: Koya SF04
Front: 19 x 8.5 - Offset 32
Rear: 19 x 9.5 - Offset 38
Tyres: Falken Azensis FK510
Front: 245/35/19
Rear: 275/30/19

That looks great! I think you nailed the offsets. I have +35 on both with your same staggered set up and I would use your offsets if I could.

Thanks, I’m really pleased with the whole set up my tyre shop recommended & no rubbing.

probably closer in diameter

Virtually exact:
Wheel Diameter Front 26.75"
Wheel Diameter Rear 26.73"

 

[YOWStinger]

I should mention I no longer have any sort of rubbing with my fitment and springs now that I've put on the Mandl ECS10

 

[Hockster]

Virtually exact:
Wheel Diameter Front 26.75"
Wheel Diameter Rear 26.73"

Although it does depend on the tire as well. I'm looking at Nitto NT255's and the 245/35 20 and 285/30 20's are exactly the same.

Yeah, that's the general guidance

 

[moinmoin]

It's always the tire. For all practical purposes, you are right, the tire diameter is (almost) the same, the difference between 26.75 and 26.73 is 2/100 of an inch, you could have that much of a difference just by losing a couple of pounds of pressure in one...
But applying math will make any difference clear and easier to make a purchasing decision.
Even the (Canadian) OEM setup is not exact, but good enough: 26.09" for the front and 26.03 for the rears, so the difference is 6/100 of an inch or 1.5mm. Nothing to worry about.

Hey guys I'm looking to order new wheels and I believe the company is going to be making custom offsets for me.
I'm going with 19x8.5/19x9.5 unless they can make me a 19x9 for the fronts I'm sticking with the staggered 8.5/9.5 but my question now is what is the best offset for fitment? I will be ordering coilovers soon within the coming month or so. I don't want to run spacers period.

Your question should be answered in here.

Sorry my apologies

No probs, I know how much it sucks to go through 20 pages of posts looking for something specific in a generic topic, I just happened to know where it was. Some people are jerks about "search for it on the internet", but I come here for conversations instead

Yeah thanks but the thing is I'm trying to plan ahead for the fitment because I can't get both the wheels and coils at the same time. Ordered the gt9 exhaust 2 weeks ago lol....

 

[YOWStinger]

Coils will let you adjust your height, but your offset is "permanent" especially if you don't want to use spacers. If you're going for that snug fitment, you're going to have to measure it out, your effective offset changes with the height of the car (as the suspension swings up around it's pivot point, the wheel moves towards the suspension, away from the fender, allowing you to be flush with a lower offset than if you're sitting at a higher height.

See this post here:
Wheel/size/offset and tire/size/profile...can be confusing.

I would suggest fitting the coilovers first, get to the height you want, then measure for tire size, wheel width, offset, diameter. Especially if you're getting custom offsets. The ranges in the post I referenced above will get you into the ballpark, but if you're looking for a precise fitment, no one is going to be able to tell you exactly what that is without the measuring.

 

[Stingerman100]

Gotcha that makes sense. Yeah sounds like I'll get the coils after all before lol.

Since this post was related to my fitment, I figured this was a good time to circle back. I haven't had any issues with rubbing yet. I haven't done any CRAZY cornering just yet, but I've driven her decently hard with the new setup and there hasn't been any rubbing.

Ok guys and gals, I have some fairly decent advice. Idk if it’s been mentioned on here, but after extensive research, I have found that every single low, middle, and high tier wheel company is using the same Chinese factory to source their wheels. My advice after finding this, is save your money and go for the TSWs or Niche if they offer the size and finish you want. If you buy the Vossins or Ferradas, you are paying 200+ a rim for a brand stamp on the face. If there is a certain style you like that an expensive company is offering, take a couple hours out of your day and find an off-brand or low tier wheel company that offers the same wheel.
