need advice about Fikse sizing

[corys69ss]

Hello, I'm new here, but a long time watcher. I am about to order a set of Fikse Profil for my 69 with 3" DSE springs. I would like to run a 17x8.5 with a 5 1/8 bs 245-45 & 17x10 (i think a 5 5/8 bs) 275-45. I can roll the lip if needed. Any advice would be greatly appreciated. You guys are the best at these matters. Fikse's are my dream wheels, but I do not want a nightmare when I get them home. Thanks Cory
