Yea the rotors on the USDM GT models and the JDM/EDM models are compatible with the BL/BP 5 platform and the BL9/BP9 to an extent
If it's DBA u desire the part numbers are on the site..but you should buy them locally. DBA T2 can be had locally and much cheaper than if you were to fly them in i'm sure.
I can't go into detail about what other parts are interchangeable cuz it is a long list..but compare the numbers for specific items and see for urself
