From experience............in the last 22 years I have run the stock 3.08 gears with ok power/accleration but,the engine will have a slight bog or lag when you shift into third at full throttle. I then installed 3.73 gears and all you do is shift,shift,shift. I personally did not like that ratio if you are going to use your car for a daily driver. I installed 3.27 gears and they are awsome! This topic is like do you like Chevys or Fords? lol lol ................Rich

3.55's for me. well balanced. great for the street and highway with out having the R's being to high

I went through this same decision of 3.55's or 3.73's. I finally went with 3.73 with my 5-speed. There is only approximately 200 rpm difference on the freeway @ 70 mph. As for shifting a lot, you can just about skip 1st gear when leaving the line from a stop. I origanally had 3.08's and find that the 3.73's are easier to drive. I could just not drive this car smoothly from a stop with the 3.08's.

I should add that I have never driven a Mustang w/3.55's. If I ever get a chance, I may like them better. Who knows? It's a tough decision.

I agree 3.55's , i drive my 91 ssp every day here in the deep south texas with 3.55's .... it's a great all around gear .
good luck ..

3.55's in my 90 Auto.Love them and was EASY to keep the speedo calibrated. Good out of the whole and not to high on the RPM's on the highway. I still averaged 18-20 MPG on the highway going to Birmingham this year.
