do any of u guys have the SVO axle girdles on your 8.8? i am trying to find one for a reasonable cost but they range from $180-200. I am also entertaining the idea of using 4.30 gears in my cobra. from the way things are going, i am probably unable to supercharge my cobra (cuz of the wife). i figure the next best thing would be some 4.30 gears. this car is normally driven 3 days out of the week at a time with 37k miles on it. any of u guys use 4.30 gears on the streets?
