man I'm an idiot PITA i had to get up early yesterday after a 9 day vacation at the beach so i was a little tired. I was looking at the shift star mod and the roller, what exactly do they do to the shaft. I tried to find posts on it but i'm not having luck. My other questions was i guess i was just looking to see if these mod's really helped people be able to shift better. thanks for the input guy's
