Hi, just purchased an arosa s 1.0, completely standard.. In process of purchasing staggered wheels, 15" x 8j rears and 7j fronts. What if like to know is what size tyre is best suited? I believe rear wheel et is 20 and fronts are 27.. Car is at standard height so would also like to know a safe figure to lower car in relation to tyre size?? Not looking for silly low but not much of an arch gap.. Cheers in advance!
