We are about to start are carpet season and this year its foam tires instead of rubber tires. What tire diameter is a good starting point for club racing? Any suggested starting points on rollouts for 19turn and stock. I have done some math based on the ratios I run with rubber tires and it seems like I'll need some smaller spurs or some big pinions to achieve the same ratios with the smaller tires. The track is 100x48. Finally get to run my FTTC4 this Saturday ( been saving it for carpet..LOL)
