Does any company sell or does any stock 6-speed Honda have a shorter gear ratio that can be swapped into the CRZ? Not an entire new transmission, just the gears. I can't find the answer anywhere. Thank you.
Not to sure, it will effect top end but improve acceleration. Could hurt highway mileage but may improve city mileage as well. Talk to rustbucket, he's running the 4.9s stock final gearing for 13/14 is 4.294, 11/12 is 4.11.
