Going to get 4:10's FRPP and having the car lowered with Eibach Pro Kit and Maximum Motorsports Caster/Camber Plates...

I currently have 2010 Mustang GT, manual, with 3:31's...I believe I am going to feel a big difference!

4.10's are sick in an auto, you're gonna have a good time keeping up with the shifts in the manual! Thats why I am going with 3.73s.

I read somewhere that 3.73's in SN95's(94-04) are equivalent to 4.10's in the S197's. If thats true I should love them. because my 98 gt had 3.73 and were AWESOME

I had my stock 3.31 replaced with FR 4.10's a few weeks ago and I am telling you, you will LOVE them. It's such a fantastic upgrade, the 3.31 is just way too high for any fun in lower rpm's. My car is actually a better DD since most of my commute is 55 mph or less. BTW, you may want to have the shop add a 4 oz. bottle of Motorcraft XL-3 friction modifier with your gear lube. My axle may have just been finicky, but it made the infamous rubbing noise in tight, slow turns, even though the shop used a synthetic lube that had a friction modifier in it. Some Ford axles just plain prefer the Motorcaft modifier. I replaced 4 oz. of gear lube with the Motorcraft XL-3 and the noise disappeared.
