Hello, I'm sorry but I'm in trouble to understand your language so I'm trying to translate in english using google translate

It's very hard and after many days I haven't understood the right choice about rims/tires

I have found this rims called RIAL VE or RIAL VIPER E with this specifications: 7.5Jx17 ET35.
The tires will be 205/40 R17. Only this dimension is admitted due to limitations in my country

Well, I'd like to know if this rims will cause troubles, but I'd like to know other rims specifications I can use with 205/40 R17 tires. 7J, 8J, ET30, ET40...

The next step will be the springs. I'd like to lower my Materia. I don't know how many cm. I have seen Eibach that is declared to lower 3cm. So I have to consider also this aspect when I will get the rims

Please give me a suggestion but also let me know your opinion about this rims.
Please also let me know what are you think about this rims with 205/40 R17 Pirelli P Zero Nero.
The price (rims+tires) will be 700 euro.
Thank you in advance.
