Okay everyone. I am thinking about making a deal with a guy that lives about 6 hours from me. He has his diff with 4.77 gears, and is looking to trade for a stock diff plus $300. It seems like hell of a deal, and we would meet about halfway and trade diffs, then go back our own ways.

Anyways, I have been doing alot of research on the 4.77's, and have seen the vids of the stock vs stock geared s2000's. The geared ones obviously beat stock ones pretty bad. Then again after reading, people are saying that it wont really benefit over 30mph, or a roll race. I never launch my car, and if I do mess with someone its from like a 20mph 1st gear roll. Would these gears still have good results for that kind of race? I also read that since you have to shift 1 more time than a stock ap1, the 1/4 mile would be about even at the end. I am just looking for something that if I pulled up beside someone, and we went from about a 20mph roll I could take off and stay there at least until 80mph.

From people that have 4.77's. I would love to hear your experience with them, good and bad.

Any help or advice would be appreciated.

 

Are you going to be racing drag/track/auto-x? If this is just for daily I think it may be overkill. I personally would go for 4.44. If the deal is too good to pass on then go for it.

 

I like my 4.77's, I just can't go in to this whole thing AGAIN. I'm sorry if I sound short.

For street = good
For track = bad

The whole thing depends though. Are you swapping them at the meeting point? Easiest thing to do is bring both cars together, swap them on the cars, drive away.

In that situation I'd say you should simply be responsible for paying to have them swapped by a shop at the meeting point. In my opinion, you shouldn't have to pay if you're simply swapping them.

4.77's aren't necessarily 'more expensive' it just costs money to install different parts from stock inside the differential. Clearly the other guy wants to be rid of them, so you should both just agree that you'll both get what you want out of a trade.

Like I said though, if you aren't mounting them back on your respective cars yourselves, I think you should just pay all costs to swap them at a shop.

That's actually what I did

 

I daily drive my car, and never actually track it. So yes pretty much for daily, and having fun on the weekends on the backroad twisties.

 

I would say a best of both worlds setup would be 4.30's or 4.44's.

anything more than that shortens the gearing too much.

4.77's would give you 1-4th gears that are as short as an ap2 except you have to rev more to get it.

 

As is often my feeling when folks ask about 4.77s, I don't understand what you mean by "overkill."

I want as much low-end torque on the street as I can get. If you're only going to be on public roads, you can pretty much afford to sacrifice as much 50mph from the top end, for the benefits of power at the low-end --- IF it didn't also have the effect of shortening your gears so much. Obviously not going to happen, but what's the benefit of 4.44's when compared to 4.77s on the street?

when you start stretching gears (4th and 5th) 4.77's start to suck compared to 4.30's and 4.44's.

but getting off the line, 4.77's probably give you quite the bit of ability to spin the tires i bet.

 

I really disagree. We have one of the highest revving engines out there. With my 4.77's I'm still only shifting into 2nd when many other cars are shifting into 3rd. I'm definitely not racing the through the gears as a super ridiculous pace.

All that said, for track use, I would stick with stock gearing and work on getting some more power through engine mods

I only think 4.77's are best used on the street. I've have friends with Stock AP1s drive my car and much prefer the perceived power difference over theirs.

 

Thats why I would just do the 4.77's if I did this. I am not going to be going over 120mph ever, and would love the extra kick it gives down low. Then reading all that i'm trying to decide if its worth going through all this trouble and a couple hundred bucks if it wont benefit my driving habits much.
