actually, it will make it even taller than running 14/62.
62 / 12 = 5.16666667
58 / 12 = 4.83333333
62 / 14 = 4.42857143
58 / 14 = 4.14285714
the lower the gear ratio, the faster you will go, slower you will accellerate, and harder you will tax your power system.
most people I know running the 58 or 60T spur are doing so because their motor is too large to move far enough forward to fit the pinion gear that they want to run. (say you want to run 62/16 but can't get the motor far enough forward with the gears on....58/15 is essentially the same gear ratio, with smaller gears, so it will fit easier.)
Only other reason to run the 58 that I know of is if you are trying to kill your motor by doing some maximum speed runs (58/17.....or maybe even be able to fit the RC10GT's 54T spur??)
