Last night I went for a drive and decided to keep it in red and I actually got used to it. I read the green is the same as the non selectable SB. Red gives you the response of a top fuel funny car. After drivining stop light to stop light for about ten miles, I got the feel of it and was able to put it back in the garage without driving it throught the back of the garage. It is definitely a fun thing to have.
