its not the miles on the rear end to break it in, its the running it and letting it cool all the way down and running it again and letting it cool down

none, don't listen to that bs

the gears are heat treated to higher temps than any driving will ever create...

but what do i know im only an EIT licensed mechanical engineer :shrug:

whats with the monkeys man ..........................so i gotta let em heat up and cool down a bit to be safe? the place is about 20 miles or so away(if i take the freeway) (40 if i take the backroads) so could i just drive it straight home or should i stop a long the way and have lunch or something and let em cool down?.................. someone tell me how much better my car is gonna be with PROPERLY installed/shimed/ not too tight 4.10 gears...i need to get pumped up because over a month with 4.10's and gettin beat by stock GT's is pissin me off[:@]

o and one more thing......when its in the shop should i put it on the dyno and have them tune it? Do u guys think i might have to adjust my A/F ratio because of my intake mods? I have heard that i might be running lean and if so i run the risk of burning my pistons?

throw a midpipe on while you're at it and then throw it on the dyno. but try not to destroy your face with your smile when you drive it.

what would u reccomend? SLP? i hear they are pretty good, i dont want to break the bank tho.......gears make that much of a difference huh so that means no more getting smoked by stock 99 auto GT's! haha
