I'll try this one in German.
Ich habe meine Tieferlegung montiert. Die Felgen sind drauf. Später diese Woche kommen rote Nabecaps und rote Bremssattellacke.

I got me a set of H&R springs and mounted them in 2 hours
It drives great!

I can speak Deutsch, aber ich can es nicht 100% ohne fehler schreiben

I always inflate them to 2,4. If you go lower, the tire will wear on the outsides. If you higher, the tire will wear on the inside.
If you use 2,3 or 2,5 that won't make a great difference. If you use 2,0 you will see the outsides wearing pretty quick.

I ordered Etabeta venti r in matt black. Should have them next week

Indeed it was 8x20

In Belgium your total diametre can't change more than 2% from the original and the tires can't come out of the wheel arche.

There only 1 more wheel that I know of in 8x20 and that is the Aez Raise.
Currently I'm looking at Etabeta venti r 8,5x20 et45, but I'm not sure if they will stay inside the wheel arche.

I see that Hyundai offers 8,5x20 et45 as an accessory on their German website. So the size should be ok.

Do you have pictures of the lowering?

3,3 is the pressure they use for transporting the car. It is hard as a rock. Did the garage deliver the car that way to you?

Sound clip?

Does it make the car harder?

Do I understand it right that you feel the everything on the road and that it makes the car to hard?

I ordered my wheels last night. They will arrive today, then go to the cnc for adjustment and should be on the car next week

Fleder Maus: Can you post pictures of the front and back to see if the wheel comes out of the fender?

It wasn' t a nice wheel, but usefull to test the size.

This was 8,5x19 et40. Not my cup of tea.

I'll order the Rh Dg in 8,5x20 et45 of Aez Raise in 8x20 et45. After a testfit I'll decide if we will bring them to et50 on the cnc.

What work has to be done on the Radkästen?

Don't Tuv and Dekra accept a radabdeckung?

I found that Brock b23 and b24 exist in 8,5x20 et50. Wolfrace has a model in the same size. The Enkei Izumo exists in 8,5x20 et48 and has a great price.

I tried a 8,5 with et40 and a 245 tire. I came out of the arche too much and it was ugly.
With a 8,5 et45 and a 245 tire the visual aspect should be ok.
