The search function can be good for "solid" answers. Like what is the stock gear ratio in a 99+ GT. For something less uniform, like what gear is best for HIS car...the search function doesn't provide info for HIS car. Other people's cars, whether they are close or not. Lots of searching around and fishing but no personal answers. Make sense?
No he would not find that answer. As you can see the guy posted down his mods/goals for the car and how he drives it. How can you provide an answer (4:10's in this example) if he didn't know any info on the car. Think about it! That is an oxymoron. Telling him to get varying opinions (search) and getting one opinion (trout's). Looks "bitter sweet" to me...
Since I've been in on most of the other identical threads, I guess I'll join this one.
Kilgore, I have installed Ford gears, Motive, and a couple of cheap no names, never saw any difference in the install. Some carriers seem to be a little more difficult to set up with any gear. 4.56 can be a real PITA because of the pin clearance in the carrier.
I love 4.10s, never thought twice about 3.73, thought often about 4.30s.
4.10s never caused a measurable loss in fuel mileage when I drove responsibly. You will stand in it more because it is fun. Ther goes the fuel.
UDTbadkarma : If you had 4.10s installed and didn't feel the difference, then I would guess that you either had them already or someone didn't put 4.10s in.
4.10s do not limit top speed. Drag does.
