Mini class are the most fun to race and the most relax, so enjoy ..... trust me.
Our Mini spec racing class (and TCS races) actually limits the M-04 pinion to 19T, and keeps the M-03's at 20T. This evens out the field a bit, as M-04's have better corner speed, figure to let the M03's have the better top end and keep it more even. Indoors, the 04 does quite well beause of its much lower CG and touring-like handling, but once outdoors on a larger track the M03's are faster in TCS races.
In regular club races outdoors we switch to black cans and 21T pinions, otherwise things would be too slow. It makes the rear traction tricky, but those who can master it tend to dominate because of the higher ratio..
