My car currently has 4.10 gears in it. I am getting a 31 spline diff and axles from a 03 Cobra. Would I notice any real difference if I switched from these gears to 4.56? 4.88? I'm not really concerned about the streetability since I find my 4.10's to be no problem now. A few hundred more rpms aren't going to bother me.
Yet another gear thread...

whew, i was sick of reading pulley threads lol
i remember talking to Bob Cosby and he said that when he tried 4.88's from 4.56's he noticed the difference, but the noise was a lot more noticeable, and since it was is DD, he went back to 4.56's...
anyhting over 4.10 will just get louder and louder. but if that doesnt bother you go 4.88
Let me just say something right now...
Naz has 4.56s...Nuff said.

If 4.56s produced more significant gear whine, you would be able to find some posts about that in the millions of gear threads out there. I have 4.56s. They produce a 'helicopter like' whisper as I hop on it over 3000rpm. Its subtle, louder than 4.10s. If you have an aftermarket exhaust...then this additional noise should not be a contributing factor in making this simple decision. You want more acceleration, then do the 4.56. But your fuel economy will take a dive since you will find yourself having a problem keeping your foot off the car. Its perfect for a DD. If I had a Viper spec T56, I would seriously consider stepping down to 4.88s.
This decision is simple. No blower in the near future, then 4.56s. Near future to me is the next 6 months and you actually are setting aside money to purchase it. Near futures is not, "Yea, I'm thinking about a blower in the future after I get the FR500 head kit and put in the coilovers and k member, blah blah blah."

You'd probably have a different opinion if every month your Exxon bill was nearly $450 based on how much I drive.
4.56 is the best all around performance gear for a street driven n/a 4.6 Cobra period if you're running the stock T45 or T3650 or 03-04 T56 or 00R T56. If you're running a T56 Viper-spec I'd go 4.88 or 5.13 since 6th gears is so highway friendly.

That's why I don't daily drive my Cobra. Of course my diesel truck don't get any better mileage, lol.

omj is right - buying a performance car and enjoying it is going to cost more than buying a camry, both in gas and insurance, so all he's saying is gas mileage shouldn't be a factor when you are building a car
gotta pay to play :burnout:

I'm such an ass. I should have looked at the sticker more closely and realized that the 17city and 24hgwy didn't mean shit. Boy am I glad you joined this website. :bored:
Defensive much?
I never said or implied that you are an ass.
I'm just stating my opinion that if you have toys, you need a daily.
I never have to worry where I park my Ranger. I'll never notice the door dings, no one will ever slash my top and steal my shit, and it will always be there when I get back to it.
I can get in my Cobra, drop the top and beat on it without worrying about excessive mileage accumulation or stressing about fixing it for work if it breaks down.
Besides, I might cry if I had to get back in it after going caving (or any other outdoor activity for that matter) for 15hrs and being soaking wet and covered in mud.

Well, believe it or not, I "worried" about fuel mileage, and drove my car Cobra to work and back every day. I was very proud of my 4.56 geared 99 Cobra getting 26 mpg+ on the highway. Good mpg is an indicator of efficiency.
All that said, 4.56s are a probably a good choice. I could not keep the 4.88s quiet, and unless it is an almost pure track car, I think they're too much.
Best of luck with whatever you go with.
