Default Rubbing Issue IS250 AWD, Genesis Track Wheels

2007 is250 awd
H&R springs
19 inch genesis track wheels.
Front:19x8
Back: 19x8.5

Now that my springs have settled, the tire rubs against the inner plastic on the passenger front side. You can see in the image where it rubs. Theirs two slightly darker areas.

The dealer has already cut a small piece of the plastic out, but it did not solve the problem. It really only rubs if my wheel is turned all the way left. Anyone know a way to fix this?

What's the offset of those? I'd assume something like +40 since they're OEM...>?

Heat gun it then mold it and spray cold water to harden where you want it....

You might have the incorrect tire size. Genesis wheels are +35mm

Where exactly is the rub mark located? Front part (nearer to the hedlight) or Rear part (nearer to the front wheel)?

What is your front tire size? Normally you shouldn't rub with that wheel spec unless you use wrong size of front tire.

1. springs don't settle. that's a myth.
2. tire size is very important. you might be running the wrong size.

I've been reading so much mixed opinion on this so I did some investigation myself after I swapped to H&R springs

Stock had 4-4.5 finger gap (rear-front)
After install had 2-2.5 finger gap
After 3 weeks had 1.5-2 finger gap

So seems like it does settle lol

I think that has something to do with the installer not resetting the spring brushes? Something like that. Im sure projectdna or Kurtz can explain it better

just because the ride height changed over a short period of time does not lead to the conclusion that the aftermarket springs are "settling".

if you actually take the time to think about the number of components that can contribute to the change in ride height after the installation of aftermarket springs, you'll realize that that it's quite possible for ride height to become marginally affected without the cause being the actual spring itself.

case in point:

- unloading and then re-loading the OEM rubber top hats
- unloading and then re-loading the OEM shocks
- deflections in the OEM bushings
- unaccounted change in front/rear/side-to-side weight distribution

believe what you want, but until there's full, conclusive evidence to show that aftermarket lowering springs degrade and sag just a few short weeks after installation, you can't rule out everything else.

Its nearer to the headlight.

My tire sizes are:

Kumho Ecsta Tires
225/35/19 in the front and 255/30/19 in the back

The plastic seems quite hard, will using a heat gun and pushing it in really work?

you seem to be running the right tires, because I run 19/35/225 up front and I don't have any issues, you should definitely try using the heat gun

In my case, I have 235/35/19 with 19x8.5 +35 rim on the front. Lowered 1 inch. I have very very minor rubbing. More like faint scuff marks rather than tearing up the plastic liner like yours. I used the heat gun and a wooden paddle to push the liner up and it helped.
