Where can I buy the trans and diff washers?
 

I was hoping someone could provide me with a link and/or part numbers so I can order the trans and rear diff washers.

If I buy from Subaru are they going to charge me too much?

Try online Subaru dealer or your local Subaru dealer.

I found it cheaper to buy online in bulk. I have enough for about 10 changes. I ended up buying crush washers for the oil changes as well.

I'm new to the BRZ; where did you buy the parts online from? Thanks.

I bought it through subarugenuineparts.com but I know a few other places like subaruonlineparts.com. Just go with whats the cheapest
