I'm trying to calibrate my speedometer gears and have an issue. The ratio I need is 2.81:1 but the closest I can get to it eithe 2.75 or 2.88. Which would be better to use? If I 'm thinking right, the 2.75 ratio would put me a little slower than my speedo says and the 2.88 would put the car a little faster than the speedo, or do I have this backwards? I'd rather have the speedo read a little fast than a little slow.
