if your having vibrations this will also affect your times.... means something isnt working smoothly

Otter you can't compare the two runs without proper traction. Get some slicks and then make some runs. My guess is you too much low end with the 4.10s causing you to spin more. Speed cost money.....how fast do you want to spend.

are u still on the stock g80 or did u swap to a trutrac or something?

Stock limited slip. The vibration feels like it did when the driveshaft blew up before. Wow Art, glad to see you one here. Hows everything? I'm thinking a retune and traction. I just recived my MT radials but I am deffinitly gonna put some slapper bars on there.

Good bro, and you can kiss that G80 goodbye when you get the MTs on. Get the Caltracs and a trutrac in there and spray off the line all day.

Thats actually a good gain for 3.73 to 4.10....i was helping on a buddies truck a few years back and he picked up 1/2 tenth on the 60' and 1 tenth all together. Also the faster you get, the harder it is to get quicker.

interesting thread, considering i need to get new gears installed... I was thinking about going from 4.10s to 4.30s, but from what i am reading it may make no difference, except a hit to my mpg... hell from the results posted above a 3.73 to 4.10 swap only gained a 1/10th, I might go with 3.73s...

G80 is the factory Limited slip? Eaton makes that right? Mine says Eaton on it. I've benn beating the poop out of it since new and no problems. Even when I spray the truck it never had a problem.When I took it apart it was very clean in there. The magnet had very little trash on it. BTW as I was typing this my vette servo showed up at my door. I'll let you guys know if it makes any diffrence at the track this weekend.
