center ring & pinion

[hardcore1]

redcat offers 2 center r&p , 33-11- or 30 -10 , same final ratio, whats the difference besides over all diamiter . they also do not tell you wich mach up , they just list all 4, i know you can not mix them up . so im assuming they go 33-11 or 30-10 ,

One is crown and pinion for the front or rear diff, the other is the centre. THey are not gearing options.
