My point is that you don't need the extra power for racing. Now if abiye is going to use the buggy for bashing and wants overkill, then the 1515 would be fine for him.
The 1515 is not more efficient because it has more torque. Motor efficiency has more to do with the design than the size. Between a 1515 and 1512 with similar kv, I think the 1515 will pull more amps and will therefore have a shorter runtime than the 1512.
