Final Drive (FD): This ratio has the single largest impact on acceleration across all gears.
4.388: Common on early base model and Type-S (02-04) units, offering a balance of acceleration and highway cruising.
4.764: Common on later performance models (05-06 Type-S, Civic Si), providing much faster acceleration but higher highway RPMs.
6th Gear (Overdrive): This ratio determines highway cruising efficiency. A smaller number (e.g., 0.659) is a taller gear for better fuel economy, while a larger number (e.g., 0.780) is a shorter gear
