You want to use the 19x8 ET57 with a H&R hub adaptor. You can use their 15mm, 20mm or 22mm adaptors depending on how you want the wheels to site in the arch. The 22mm will give you an offset of ET35 which is the lowest you can get away with an 8" rim. If you want a set let me know and I will get you a price.
The 11s will not go no the rear, I will be putting some 10s on the back on my newly aquired B6 Avant and they are tight!! The 11 will not go any where near without serious arch mods.
