A factory wide box had a 2:52 first gear. A factory close ratio or M-22 had a 2:20 first gear. The M22W has a 2:56 first gear. My car had a close ratio 2:20 first gear in it and with the 2:56 in it now it winds up a lot faster in first gear. The spread between the other gears is pretty even and the car runs a lot better through the gears also. They also have a M22Z which has a 2:98 first gear. By using their formula going from the 2:20 to the 2:56 first gear it makes my 3:55 rear end gear ratio feel more like 4:10's in first gear.
