This kit cost me around AUD$500.
Well the OP doesn't really have much option otherwise.
Sell the kit to Adam and go TRD instead!
I'm happy to sell it at my original purchase price if anyone want it.
Yes I just did a quick search as well, very hard to understand the Taiwan web pages even with translator however you're spot on it seems like it's just a 26mm rotor.
Andrew357 - True the Akebono calipers seem much smaller and not as well made as the PBR ones.
I'm interested actually to see whether this mob makes a rear upgrade kit, even if it is just a caliper relocating set up.
Thanks to everyone that gave me such a good information and advice. it looks like my only option is get an akebone caliper on to my aurion.
Steve,
I think from memory, when I purchase front setup, they did said they have rear caliper relocating kit. but I was told because it's front wheel drive, there is not much improvement from the rear kit. but again don't know if the calipers are the same as australia aurion.
