Right now I have the stock 2.73s in my car, when i went to the track in July I ran 14.2 - 14.3 seconds at 100-101mph. My 60ft times were really bad they 2.2 - 2.3 seconds. I was running on my street tires (Dunlop SP sport), the temp was 84 degrees and 80% humidity(not ideal). I am thinking about getting 3.55 gears, this is my daily driver in the summer. What kind of gains am I looking at here? Some people I was talking with said that the car would not pull as hard at the top end of the track, what do you think? My mods are in the sig, I plan on getting a supercharger in the future, maby this year or next. So what are the pros and cons?
