New Castle Gearing

What would be a good starting gear ratio for New Castle 206 with a green slide?

NCMP has these recommendations for gearing tucked away on their website.

Assuming you and your driver are fairly new, that 3.3 to 3.4 will probably get you started just fine. If your driver comes in and was on the limiter, drop a tooth. Repeat until lap times slow down. Then go back 1 tooth.
