1) Just the diameter. The cars are heavier and wheels are bigger now to fit suitable size rotors finally. Our new WRX's all have 290mm vented rears, the Outback and legacy ( liberty 2.5 ) have 290mm solid rotors.
2) For some reason USDM part numbers are different in some cases for the same part. This number is correct in Aust, Japan, Europe. All 4 wheel disc Subaru's have 170mm handbrakes except for Special edition STi's which have a R180 rear diff for rally / track applications. This version has a 190mm handbrake.
I'm still collecting part numbers for conversion to USDM and I haven't confirmed 26700AE04A yet. The problem is that the left hand doesn't have a clue what the right is doing when it comes to getting global part information. We get more help from you guys than the dealers.
I guess I wasn't clear - my question is what is the difference, if any, between the H6 rears and the rest of the 3rd Gen Legacy rears. Everyone posts like there is a specific difference but I just don't see what it is?
The PN 26700AE04A is what 1) three (3) dealers told me, 2) in the database of every online source I can find and 3) on the box of the parts I have sitting here. I guess I don't know how much more "confirmed" I can make it
