Stock spring with aftermarket wheels

[sota-stinger]

Hey all! New to the forum, and my brain is spinning on what to do next. I thought about getting some new wheels, however I don't really want to deal with lowering springs as winter is a thing where I live. I've previously had 19's on a lowered Nissan and hated it. With that being said, anyone running 19's with stock springs? Can't seem to find any pictures, everything I'm finding is also with the Eibach's. Thanks!

Stock Stingers do come with 19 inch wheels. I am not sure if I understood your question correctly.

 

[sota-stinger]

Mine didn't...that's probably why I was confused. I have an AWD with 225/45R18

Mine came with 19' wheels. 2019 GT2 AWD.

If you are looking for ideas and do not like how rear end lifs in corners upgrade sways.

Awe you have a baby GT lol. Look into the stock 19s...I had no issues in winter weather.

 

[sota-stinger]

Lol I know. Thought they were 19s til I looked at the tires. Knew something wasn't right.

I was thinking aftermarket but not sure how they'll look with stick springs.

The TSW line is very appealing!

19s with stock springs will look just like stock stingers with 19s (assuming same width, offset, and tire size). Plenty of pictures of Kia Stingers with 19" wheels around, including directly on Kia's website.

Lot of good information for you in this thread.

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

 

[sota-stinger]

Perfect, thank you!

As long as you change to a tyre size that maintains a similar rolling diameter, you will be fine.

All that will change is that the tyre sidewall will be a little smaller, and the wheel (not the tyre) will "fill" the arches a bit better.

Just be sure to maintain a 'squared' setup on the AWD - the same wheel and tyre size on all four wheels. Staggered wheels front to rear will cause grief for the AWD system.

Explain the “cause grief for the awd” comment please?

Why would that be?

 

[Manaz]

Why would that be?

If you run a staggered setup, the rolling diameter may (almost certainly will) vary from front to rear. Without getting into a lot of detail (I can if you'd like), different rolling diameters front to rear is generally a bad thing for AWD drivetrains, because the different rotational speeds of the wheels causes the AWD system to suffer additional stress.

Effectively - if you have different rolling diameters front to rear, the wheels will rotate at different speeds (revolutions per minute) at a given road speed. This variation in speeds comes together in the AWD system, and means that you're asking the system to cope with that over a sustained period of time.

Yes, there's variation in front to rear rotational speeds during cornering, I get that - but it is at lower speeds, and generally doesn't happen for sustained periods of time. Run different rolling diameters front to rear, and it happens every second the car is in motion (and for sustained periods like highway driving), and gives the transmission little time for recovery.

tl;dr: Don't do it unless you want to be up for expensive repairs to the AWD system that Kia won't (and shouldn't) cover under warranty.

If that is the case, why would Kia sell me a AWD Stinger with Staggered setup?

So 1st. Mine came with staggered 19” OEM (awd 3.3) pilot sport 4

The Diam is minimally different.
Front 26.1 (797 revs per mile)
Rear 26 (799 revs per mile).

2nd my winter setup was slightly smaller (but square).
25.9 (803 revs per mile).

No calibration / setting changes/ tune needed.

The only drawback for staggered would be accelerated rear wear since you can only rotate side to side. Hence they only last 9k—15k (for most drivers).

Interesting. It was my understanding that the AWD models all came with a squared setup.

The variation in the stock setup must be within tolerance. Good to know.

In that case, I was wrong (at an absolute level) - but I'd be very cautious exceeding the stock levels of variation, for exactly the reasons I ran through.

No issue here, because all four wheels on the car are identical.

The car won't care about variation from stock to whatever you run, because they don't run at the same time. You may get a small amount of speedo variation, that's about it.

?? And I didn’t say there was an issue.??

Sorry, I misinterpreted this then:
