If set on running the RB pistons, using the Centric/Stoptech seals instead may be the way to go as FuelTech did.

According to a source who runs the RB's, the regular RB dust boots crack just like the stock boots at the track. Although not brake fluid compatible, the high temp dust boot option by RB appears to be the better choice if you don't want to deal with changing boots on a regular basis (assuming the leaking issue has been addressed).
