May only be of little help but the FSVT wheel is not very brake friendly. This I know as I cannot fit even an NDL caliper on a .81 rotor kit.
Granted the PBR is narrower in design slightly as it's a floater, but it's on a 1.10 rotor as well. And neither kit can place the rotor far side inboard very far. Matter of fact I'll wager the Baear and my .81 are about the same total height at about 1.6"
I'd keep shopping of big brakes are on your hit list.
