wrong^ stop spreading incorrect info in this thread. Im currently doing this swap. He WILL need a complete 06 sti rear. It has a 3.54 ring. You cant just swap the hub in the rear. The axles from the r160 are completely different. You are right about the front, you need 05+ sti front knuckles and front shocks or new collars for your coilovers. You will also need the abs rings adapters from 6gun. I recomend getting sti front axles also as they arent the crappy tripod style. Since you have a 05 you have male-male axles. Then of course you need wheels. I dont think ive missed anything.
