I wasn't going to mod my 03 much. I was one of the first to get one in June of 2002. I owned 99 and 01 Cobras so my first mods on my 03 were the same as my other Cobras, Bassani x-pipe and CB and then 4.10 gears a month later. The car made arounf 410 rwhp and 395 rwt at the the time. The 03 was the first car I ran at the track with ET Streets. I had a 2.80 pulley before I made my first pass on the ET Streets. It would trap over 7k rpm in third on an 1/8 and about the same revs in fourth on a 1/4. I didn't like carrying that many revs across the line so I swapped them out to 3.90 gears that pull about 6200 rpm across the line. As far as times, they were about the same.
I would only do 3.90's and only if you are planning to run it at the track a lot and don't plan on getting over 500 rwhp. My best sixty foot on the stock IRS with the 3.90's was 1.52 on a 100 degree day. It traps 123. I just drove an 03 for a few days with 460 rwhp and my car would destroy that car on a roll. But, if you plan on street racing from a dig "forgetaboutit". My car when I ran the stock F1's with a 2.80 upper and four pound lower would roast them in second easily with just throttle at 40-50 mph. All you had to do was mash it a little, no clutch. On cool nights on smooth pavement I could roll them pretty good in third at 70 mph if that tells you what is too much for the street. Off the line on the street in first you will not be able to get anywhere and you will lose to a car running 100 HP less. At the track on MT tires it is a different story. Lovem or hatem. I'll take mine but when I go to a KB next spring I'll probably drop to 3.73's or maybe even back to 3.55's. If you plan on running stock boost and maybe only exhaust mods, then I'd do the 4.10's. Other than that, stick with the 3.55's.

Silver03Snake: when you say your car would destroy that car from a roll, how fast of a roll are you talking about? I have had geared mustangs (4.10's in a 5.0, 4.10's in a bullitt, and 4.30's in a mach 1) and roll on speed was better than stock on anything below 50mph but I thought that when going freeway speeds and faster those 4.xx gears sucked when it came to roll on acceleration.
