What do you have for motor?
Sweet spots for:
- Rpm
- Torque
- Cruise/fuel economy
What do you anticipate your percentages of auto-x / track usage vs. general road usage?
With the Vipers semi-wide ratio I'd be leaning to 3:73, but 3:55 gearing will typically provide more traction.
With my close ratio T56 mag I'm leaning to 3:55 with a 26.4" tire. The reality is even though my desire is to track and auto-x it, the car will be spending a much larger percentage of it's time on public roads so that's where I'm focusing on optimizing the ratios. My motor likes to cruise at 2,200 so 5th is for 60-65 mph, and 6th is for open range cruising since 2,200 is about 82 mph.
Without a quickchange rear end we'll always be compromising somewhere.
