besides changing the internal drive ratio, what other benefits are there to changing the diff pulleys to the white pulleys? Are they machined from delrin (hence the white color), slightly larger. or it just cause they look trick?
with the higher internal ratio, (2.25 with the white diff to 2.1875 stock) you would have to go up almost one tooth on the pinion to achieve the same roll-out ratio? perhaps the change is better suited for modified racing?
