To a noob who doesnt know what the hell you guys are talking about when you say 3.3 or 4.1 gear ratios what the hell does that mean and how does it make ur car faster?

Just think of it as a ten speed bike, when you are in the lowest gear you can take off realy fast like 3.73 or 4.10 would do to your car, Now imagin you are in 4th on your bike ond you try to take off, doesnt work so good witch is kinda like the gearing you have now 2.73or3.08 witch are too high... But you wont go any faster you will be quicker as like your bike, you cant go vary fast in 1st gear, though yor tranny takes care of that problem. So it basicaly it boils down too you will get off the line quicker and your acceleration will be better. Hope this helps. oooooo i almost forgot thees gears are in your rear differential btw.

noob

which gear ratio is the best?

Razor19

Depends on your situation. If you have a FI car or are planning on FI go with 3.73's. If you have N/A and plan on staying N/A most people say go with 4.10's. Some peopel say 4.10's is overkill some people say its not.

ok what the heck is FI and N/a lol what would be the difference?

Razor19

FI = Forced Induction aka Supercharger and Turbocharger
N/A = Naturally Aspirated (when you dont have a supercharger or turbocharger)

How does changing gear ratios to 3.73 or 4.10 affect high speed sustained driving, such as highway?

ShadowG03

The higher the gear ratio the higher your RPM's will be at highway speeds 3.73 won't be to bad but with 4.10 you'll probably be running about 3000 rpms at around 70 mph. But some people only cruise around town with there stangs so 4.10 are reasonable, I wouldn't be going on any road trips with 4.10's.

Actually most FI people with any real amount of HP go with 3.55s. 4.10s for light mods 3.73s for mild mods and 3.55s for heavy mods. You can do 3.73s with a FI car or even 4.10s but traction is an issue.
