Just bought a used 2008 GT with 28,000 miles. I want to change rear end gears for a better launch Do I go 3.73 or 3.90? I hear all 3.90 gears are noisy.

Welcome to StangNet -
Just my 2 cents - and I'm not a dragster / beat on my car type - but I love my 4:10's - if you want the feel - slam you in the back of your seat when pulling off the line - then I'd go with those - but like anything - you'll probably get a 100 different opinions - may help if state whether you have an automatic or 5 - speed -

3.73's are the best gear for the automatics. The manual works best with 4.10's but with the gearing of the auto it works best with 3.73's IMHO.
