Changing rear drive motors max output

Forewarning my team recently switched from Java to LabView so I know little to none of the language.

We currently have a problem in which the two rear motors have a different gear ratio than the front two, the rear has to be set to 75% and the front is keep at 100%, the only way I can thin of fixing this is to rewrite the Talon control VI and I wanted to know if had a better way of fixing it.

It is an arcade drive system using the basic setup given to you as a starter project.

Sounds like a poor mechanical design decision, but that’s your robot, not mine.

You can multiply the output by 0.75 before feeding that into the Motor Set Output vi.
