AAAAAAAAAAAAAAAAAAAAA, too happy!!!!
I am expecting -1.5s from 0 to 200 (0-125 MPH) .
It is only 3.15, so -7% compared to the stock 2.93. Not so much someone could say, but I need the car to travel at high speeds .
It will be like to gain 25 HP, I think .
It was more than a year that I want to make this mod!!
I will update you about the result

Congrats alex
Did you just do a ring and pinion swap. If so, where did you find the parts. Dinan for example swaps out the entire dif.
I understand your desire for high end speed but I think you could have gone a little shorter (for mor grunt) and not compromise top end.

With -15% (3.38) you would obtain a good acceleration, but it is very unconfortable at 100 MPH on the highway .
Are you the next, Al ?

Nice Alex - good balance of ratio chosen for your situation.
who supplied the parts/who did the job ?
The best thing to do is decide which ratio you want and then mail all these suppliers asking for the price
Who did the job .. Parts arrived this morning . I scheduled the job for the first days of December .
Will see .
