My drag is about 35% lower so basically I would need 35% taller gearing. At the moment 100 km/h or 62 mph is 1950 rpm. If I am lucky I will get custom main gear price >1000€. My tires are 7% taller and there are no taller gears available for this gearbox.
If I have to use current gearbox I have to do more P&G driving to get better engine efficiency.
