Show me in the ROAR Rules where it states you cannot alter the timing range of a motor, because I cannot find it.

Grinding the timing ring does not alter any base dimensions or specifications of an approved motor. I've never had to max the available timing on any other motor, so trying to get more out of those would only melt it into a puddle.



edit: If ROAR cared about timing range they would set a max internal+adjustable percent I would think.

Just to make things clear, I run TSR's because they are awesome but I feel the Trackstar is good for the longevity and affordability of the sport.
