I dont know why Man ...but your not supposed to stay on it...honestly I dont need to stay on 5th when I throw 5 and step on it for that maybe second or 2 Im already at like 120 ...I just care about the safety of my motor.....me and a couple freinds with the type-s' all do the same ...I guess some of you guys just know too much or think you do anyways......
....rather be safe, I thought some of those things too , but Im still at the point were I am content with the car and how it pics up speed .....I dont know about those other cars going through all gears , but my info might not be right but its safe, and thats fine for me!
