Installed rims???

[Neufcruz]

I just received my 26" Luya rims. I installed the disk on front and of course the rotor bolts that came with rotors rub. I have some red anodized bolts that look lower profile so oping will solve that issue. Need star wrench.
The rear seems a bit more dificult. I installed rim and sprocket. My question is do I need to get the Top Hat adapter to run a disk on rear? Whether I go jack shaft or not, seems like the disk would be way off without.

Does anyone know what adapter I need to install a disk on the rear for a luya rim. Anything specific or just order a Top hat? I think thats what it was called.
