replacing motor bearings, do brca allow?

[catman79]

hi, looking for some clarification,
I'm looking at purchasing a new motor for the upcoming indoor winter series, the motor I want Is on the brca list, the company also sells uprated bearings to fit the motors, I just wanted to know if this would then deem the motor illegal? ive looked on the brca website and I think its allowed, just wondered if anyone has crossed this bridge before?

thanks in advance.
