Got an appointment to install 3.73s and .....
I called Coast Driveline & Gear in Ventura and scheduled the install of 3.73s from my current 3.31s for next Friday. Perfect was the comment from their man on the phone. But he also asked me some other questions about if I wanted to install their one piece Aluminum drive shaft at that time and also if I wanted to do any thing with the tracloc unit. He will charge no additional labor for the replacement drive shaft if installed with the Gears. I was concerned about vibration to which he said he would be sure to set it up so that there would be none and that they had customers running their shafts in Mustangs over 150Mph without any vibration so long as they don't mess with the suspension after the install. That the advantage of the lighter rotating mass would be faster acceleration and the elimination of much of the drive line backlash.
So I am wondering if any one else went through the expense of replacing their two part steel shaft with one of the after market ones or one of Coast's and how did it work out for you.
Then we got into if I wanted to do anything with the tracloc or replace it with something else. I don't race my GT. I just enjoy spirited jumps on the freeway and an occausional stick it to them for the pass. Don't do burn outs more than a little squeek off the line. Maybe.
I am interested in the carbon disks for the tracloc. My GT 08 has 8000 miles on it. I think my clutch disks are fine. But seeing that its open for the gear exchange, I am considering putting in the carbon discs because I expect longer clutch life because of them.
But before I spring for the discs and the additional labor of rebuilding the carrier, I want to know if there is a down side to using the carbon disks.
