Im new to the Forum and just need peoples input in this. I brought my first Passat in July and shes still running well and im very happy

Ive thought about the S8 wheels and the old RS4 wheels and also about size and im undecided about whether to go for 18" or 19".
Anybody got any thoughts on this or had any good or bad experiances with either size or designs?? as i would like to upgrade from the stock wheels
Cheerz guys
