Offset is not going to stop rims clearing Brembo callipers the spoke design will, example just tried fitting some Rota Titan 17x8 +42 and they do not clear the huge Brembo. I am running oz alleggerita 18x8+48 offset and they clear, but by not much maybe a key width between the caliper face and rim spoke. 225 235 fit without throwing speedo out unless you going to 18" then a 40 profile will fix speedo issue.
