A3 2.0TDI Wheel Upgrade

[Rhys]

Hi,

I am looking for a set of wheels for my 2014 A3 8V 2.0TDI which is currently running a set of Audi 17" wheels. 

The recommended size for 17" and 18" alloys according to wheel-size.com is...
225/45R17 92V    7.5Jx17 ET51    5x112
225/40R18 92V    7.5Jx18 ET49    5x112

I have seen a set of 2018 S3 wheels for sale which have the following specifciations and wondered if anyone has any experience of fitting these please?

The specs are:
Audi Part No: 8V0 601 025 M
Rim Width: 7.5J
Offset: ET51
Cente Bore: 57.1mm
Tyre size: 225/40/R18

Thanks in advance

Rhys
