Yeah they are standard 52mm rod bearings. You'll just need to order two sets. I have a feeling the mains will be simular in the fact that they will match some other Subaru bearing but will just need to order two sets to make one set and some spares. I'll have to pull up the part number on the rod bearings in a second. I need to either look it up or grab my notebook I know i have it writen in on a STi build's part list.
