My current diff is one that Jeff built and they are cryo treated. (I bought it second-hand.) I can vouch that they have been trouble free and are silent.

 

thanks! so 1155 includes the basic packaged installed? the 4.77's are normally pretty quiet correct?

 

I may be down for this. I just recently moved into my new place so money is a bit tight right now. Let me see if I can get the money together for the basic 4.77 package. The old lady is gonna kill me lol. Im assuming payment needs to me made to you jeff over the phone prior to you arriving in quantico?? O and by the way, the sebring hardtop arrived and looks great on my car jeff, thanks so much!

 

ill be there probably but noy gettin gears. i just miss skip soooooooo much

 

could i just get the re-inforced diff housing? and the cryo? or is the cryo only use with the greas??

 

i want to get these but how much is it a pain in the butt for lets say you still have warranty on your car and would still like the dealership not to notice the gearing and how much faster would the 4.56's our cars? ive heard of the 4.77's being able to shave .3secs of the 1/4 mile and keep up with a S/C but what about the 4.56?

 

Most techs would never know unless they've driven many S's. Even then, they might think, "Wow! This a strong S2000." This isn't because the gears don't make a difference, but because of the techs just don't see/drive that many of them.

 

would cryo treated 4.77's whine a great deal...I rode in a 4.77 geared S and the wine was kinda crazy..maybe it was the install

 

I'm a little confused about the pricing. If I go to hardtopguy.com, the price for 4.77's with speedo calibrator is $955. Am I missing something? Is the labor for speedo calibration $250?

 

maybe i shouldnt assume but i assumed they were unistalling and reinstalling the diff onto your vehicle for the prices quoted
