I know you guys probably get this a lot, but I am having a lot of trouble deciding which spacers to get. My car is a B5 A4 on coilovers, and running Flat Fives off a Euro A8 (18x85, et +45), wrapped in 215/35 tires. I am pretty confident in getting 15mm for the front, but I am unsure as to what I can pull off in the rear. A lot of people have told me that +35 on 8.5in rims is the sweet spot to for flush, but I want the car to sit very wide in the rear, but not awkwardly wide. My problem is that I don't want to get 25mm spacers, and then be looking like my wheels are way too wide for my car. Another issue is that I don't know how much lower I can go in the back. My coilovers have about 1.5in of threads left in the back, and I can put at least 3 fingers in my wheel gap. What would you guys recommend doing? Maxing out my rear coils to see how low I can go, then go from there?
