The 4.56's went in this morning after sitting in my garage for almost a year...Lemme tell you, the break in period is going to be tough...that car wants to just go now...I punched it in 5th on the highway doing 45 to get by some traffic and I was up to 70 before I knew it...



If they don't consistantly keep me in the 12's I'm going to give up and put her back to stock and just drive it... :damnit:

what RPM are you running at 70MPH. I was just wondering, I run around 2800 @70 with 4:10"s, and have thought about putting 4:56"s in. This is my daily driver and I travel to car shows several times a year so I don't want it up to high

I'm not real sure that I have my speedcal set up right yet or not...I'm borrowing a friends GPS to find out for sure...

Anyways, using a gear/rpm calculator, 70mph with 4.56's should be right around 2800rpm

Good luck with the gears, if I ever get my 6 speed, they will reside in my cobra, kinda nervous with the stock t-45.
