Okay, I have done a TON of research on this site regarding this topic but have not been able to come up with a solid answer. However, there was a few facts that I was able to come up with.

4.77's are FAR too aggressive for a daily driven AP2 due to low top end and tons of shifting necessary for daily driving.

4.57's on the AP2 are like 4.77's on the AP1, which means it might still be a pain in the ass to daily drive; but I'm not 100% sure on that.

4.44's seem like the best option for us AP2 drivers, as it techniquelly puts us in the same boat as AP1's with 4.57's. This is supposedly due to the different ratios for gears 1-4 between the AP2 and AP1.

Can anyone (xviper, wisconsin) give me and everyone else some final insight on what the deal is and maybe make this a sticky, since:

a) the search rarely works correctly

b) I'm sure tons of AP2 owners would like to know the information.

Thanks in advance for any help given!

 

Personally I like the 4.57. They were designed with AP2 in mind. It is a 4.77 low and a 4.44 up high. I have an AP1 with an AP2 transmission. Only the speed in each gear is differant from an AP1 w/AP2 tranny and the AP2. The car was a blast to drive. It just got up and went.

Also, there is a number of AP2 owners with these gears and they say the same thing.


Here is the math.


AP2 Changes vers AP1
Gears 1-4 = 4% lower for performance
Gear 5 = 1% lower
Gear 6 = 2% higher

4.10 Gears
1-4 = 4.223
5 = 4.141
6 = 4.018

4.44 Gears
1-4 = 4.6176
5 = 4.4844
6 = 4.3512

4.57 Gears
1-4 = 4.7528
5 = 4.6157
6 = 4.4786

4.77 Gears
1-4 = 4.9608
5 = 4.8177
6 = 4.6746

 

It's all preference. Have you considered 4.3?

 

i think anything under a 4.57 on an AP2 wont be worth the $1k+ you have to spend to buy/install

 

Have you tried to find a set? Non-existant

 

I honestly want to go with 4.77's, but I've just heard that they are far too aggressive. I don't know if that is 100% true or not.

I've been told 4.44's won't even give me a noticeable difference, which is obviously something I want to avoid.

4.57 will basicly be 4.77 in 1-4 and a 4.44 in 6th. Turst me, you will know the differance by feel.

Good news men. This could be the "final" time you have to dicuss this one. Maybe we should do this with more topics, then just refer everyone to the "final" threads.

Just kidding ofcourse. I vote 4.57

4.57's on an AP2 doesn't require a 5th gear shift in the quarter mile, right? But 4.77's do?

 

i just got the 4.57r from HTG and it should be installed tommorrow. will let you know how it turns out!
