Servus, I’ve been looking on the net and here in the forum for a while now, but I’m not that smart. Summer will soon come back and I want to replace the winter rims and pack a different tire size directly on it. Entered and driven is currently in front and rear 255/40 r19 u d as rim 19×9.0 , et I don’t know of the unfortunately. I would like to drive for the summer 20 inches. Since I plan to upgrade the brembo also in the future, I don’t know how the e I would like to drive 285/40 in the back and just keep 255/40 in the front. What do I have to pay attention to now when buying rims? Would not like to drive different rim sizes at the front and rear. According to a table in the net, therefore, a 20×10 rim for 255 and 285 is enough. How high can the Et be? In the net are several with et30 or et42 or et50. That I have to go to TÜV is clear to me, just don’t want to have any problems there and just as little i Find out for a year that the brembosattel doesn’t fit now Can you help me?
