Probably should have mentioned this rule. The gear set has to be from a boxster

Any internal gear(s) from the original manufacturer (or donor vehicle manufacturer in the case of an engine/transmission swap) may be used, provided they originate from a model that is eligible for competition in ST5, and they are not straight cut/dog ring gears
