Offset Question - Any Help Appreciated

[akakooper]

Have a chanch to pick up some wheels from a friend on the cheap. would be going on my 09 4.6

Here are the details:

22x9 +35
22x10.5 +38

My concern is the rear offset. I used the "willtheyfit" website. Looks like they will poke out 42.1mm more then factory. Is this going to put me into a situation where the rim is past the outside of the fender?

thanks in advance for replies.

88 views and no replies sorry man. I saw this the other day but have been too busy to check it out. Here is how I looked at this. This setup below has been installed on another forum members car and fit. Keep in mind he was on air and ride height is really low.

20x9+7
20x10.5 +23

Your setup compared to this in the front would be 28mm (approx 1 1/8") inside the fender well and closer to the strut. His rim/tire was almost flush with inner fender well.

Compared to rear would be 15mm (approx 5/8") inside the fender well and closer to the strut. His rim/tire was almost flush with inner fender well.

With the factory offset being +38 it looks like they wont stick outside the fender at a lowered ride height but would be close at stock height. Only thing that I would be concerned about is how much closer it puts the tire to the strut. The rears compared to stock show it being 44.5mm (1.75") closer to the strut. Without getting under the car and measuring I can't remember if there is that much extra room between them on stock wheels/tires.

Also when I compare your front setup to mine, 20x9.5+8, looks like it will be 20.7mm (approx 13/16") closer to the strut. I don't think there is going to be enough room for that because when I test fit my wheels I could only fit my pinky in between the tire and bottom of spring perch.

To sum it all up the wheels will sit inside the fender at lowered ride height but may stick out slightly at stock ride height BUT may not fit due to lack of clearance between tire and strut assembly.

Hope this didn't get too confusing by comparing 4 different setups. Best thing to do would be a quick test fitment if possible. I am not a tire offset/fitment expert by any means.

Wow, amazing reply!! The more I thought about it, I figured the portion that might be past the fender was the least of my worries. I found a different set of 22's.

22x9 square set up +38 or +40. Gonna dry fit tomorrow I think.


Again, thanks for the reply. I don't think many are interested in 22's here. If I get them will post picks and get my video up with muffler delete.

Yeah most people on here aren't interested in form over function. Personally I think 22's are too big on a Genesis. 20's fit quite nicely with a 1.5-3" drop.

Still think you are going to have lack clearance between wheel and strut with the 9 wide and +38. If you are going with a 9 to have same clearance as the stock rims you would need an offset of +12 to +15

Agreed with your assessment. You will need to pay attention to disk as well- I am running 10mm spacers to clear the brakes...they're pretty beefy. Offset is +21 on 8.5, so +11 overall. It is essentially flush at 1.5" lowered

Thanks again gents for your replies! The offset is actually +35. I did a dry fit yesterday and the hub bore on the rims is too small - 60.1mm. They are going to widen the hub to fit our 67.1mm bore. Will be nice they are hub centric w/o rings. The wheels are Road Force RF 14. They typically do not come in our bolt pattern. The wheels I'm trying to purchase were a one off bolt pattern for a lexus here in town. Combine that with the change in the hub bore and there should not be anyone running around with the same wheels on a Gen. During the dry fit, the shop confirmed clearance of the front brakes. Fingers crossed that everything works out and fits correctly.

I also added my best rendering of the wheels on a white 4.6. I understand this is not for everyone and most may not like it. cool with me..........

I like the style of the wheel. Good luck!

 

[xiaphin]

I wouldnt have picked out that style of wheel for the Genesis but I agree with Tailwalker the style does fit the car. Personally think the 22's are too big and would look better with 20's and a drop. At the end of the day it is your car and if that's how you want it then go for it. I'm sure some people wont like the direction I am going with my car, and I am ok with that.

Wheels are nice but just too big. Being that the spokes go all the way to the edge 20s would have looked great.
Also since it's a rendering he drop is way more than what you will see which I think will make the look much worse.

Can you repeat your last sentence? The tires I currently run are 27.2 inches inflated. New tires are 28 inches inflated. 245/30r22 toyo proxy 4. Figure the slight increase in tire size should eat up some fender gap while staying under 3% increase over oem. Even one certainly has their perspective. I love that we can all have the same passion for our cars but add our own twists. Thanks for the replies and suggestions. Will know in a couple days.

Nice looking car and wheel!

I believe you have that in reverse. Most people here are form over function. As a functional setup, you start seeing real negative affects to handling, road manners, and long term reliability with offset variances of more than ~10-15mm from stock. The +12 and +15mm offsets you mentioned are too low for a car like this and very much a drastic enough change to make a difference you will feel driving around town.

 

[Tailwalker]

You are correct. The car responds and handles much better with coils and a drop of 1.5" and +21 offset all around...firm and planted. Rides better too. Better form, better function.
