[8P] 5-Arm-Wing-Design - Need Advise

Hello Everyone,

Firstly i'm sorry for posting in English, my German isn't great.
I am currenlty looking into upgrading my 8P Sportback (2011) and I need Inputs from the community.

Questions:

  1. I currently have 225/35 7.5X18 Doppelspeichen Design Summer wheels.
    I'd like the "5-Arm-Wing-Design" 235/35 8x19, will these wheels fit without any Problem? (TÜV)

  2. I'd also like to lower the car a little and get the wheels a bit outer (spurverbreiterung).
    What's the advisable width? (Front and Rear)

Thanks in advance for the advise.

Do you mean the "Rotor"-Design?

I mean these

The wheels should fit:
