I own the 03 Cobra with the weird noise. The rear end is going to be rebuilt due to a few issues. I wanted to know if any other 03-04 Cobra owners change their gears and if so to what gear? I drive the car daily and often travel from state to state to visit family and friends. The car won't see the track but maybe once to see how the new gaers work. The car pushes around 2800 rpms at 90mph once in 6th gear. Should I have the same gear (3.55) or change to 3.73's or 3.90's?

I have 373's and love them. Great on highway and great for racing. All around good gears.

Depends on your mods. If you have plans on high power and want some sort of traction the stock gears are great, otherwise if you are stock for the most part a 3.73 wouldn't be a bad upgrade. I would never change out my 3.55's.
4.10's would be fun lol
Man Craig you have some big plans for that Shelby huh lol next thing I know you'll have a polished KB 2.8 under there.
