For reference, I believe the correct transmission for my EZ30R is a STi RA close ratio gearset with a 3.90 final drive. This will net about 3200rpms at 70 miles per hour and let me carry 2nd gear to close to 70 miles per hour (my goal for autocross!). I'm currently running the close ratio gearset with the original 4.44 final drive and its just too short.
Why not a 4.11 final drive for auto-X?

Does an sti 6 spd be better for highway, gas millage?
