Manny,

Since you are working on a Ford, this site will possibly help. It also lists the various ratios for the T5 tranmissions of the Ford cars.

FYI...we found the best ratio was the 3.4, using final drive of 1:1, and 14 in tires.

Good racing.

PM me your email address and I will send you two different MS Excel gear calculators that will help you choose ratios and the effects they have on speed and RPM drop.
