Yes, the car is jumpy off the line and out of the corners Well, for small tracks, that kind of gear ratio comes in handy to outwit, outlast and outplay those other cars equipped with 5 port Rodys on the track especially if it's a small one The trick is throttle control and the rest is car setup.

I don't have any problems with regards to spurs and pulleys stripping. Only problem is when stones get into the drive train... But then the belts will go first and this is only the front. The sides and rear belts do no exihibit the problem.

I don't think there's any law of diminishing returns applying on this one... The higher the better Of course there are limits to it... Just that make sure your 1st and 2nd gear ratio is close enough that the engine does not bog out when jumping from 1st gear to 2nd gear. Of course, set your 2nd speed so that the gear ratio is enough for the engine RPM to peak at the end of the track's longest straight.
