STI HD9 6+1 for me. When I got my Turbo S those were about the only beadlock wheels you could get that were the same as the factory offset. With the HD9's my width was the same as stock using a 32x9.5x15 EFX Motovator tire.
STI has a few options now, Look at the HDA1.. comes Machined or Black with a +40 offset and stock is about 55. Only pushed out about 1/2 inch on either side or an inch total.
