Wheel offset on 2000 Audi S6 changing 35mm to 42mm

[technics100]

I have a 2000 Audi S6 that surrently has 8 x 17inch wheels with ET35mm, I am looking to change the wheels to Replica S3 ones which only come in a 8 x 18inch with either a ET42mm. This will mean the alloys will sit 7mm closer to the centre of the car, I don't think they will hit anything as they are only a 8inch rim, Will they be OK?

Cheers

might look funny, but should be fine
