I noticed that the bottom of the chasis (from the inside) always has a mark of the belt .... i assume that it is touching sometimes.
Having less rotating weight (41T Pulley) should help always, no?
Can I calculate it somehow the ratio with two 41T pullies?
Do you really recommend me to try a gear ratio of approx. 5, if other drivers using other cars have approx. 4.6 overall ratio?
