so i just got my 4.10s installed yesterday and i love em!!! now the only question i have is what is the break in period? do i have to have some crazy amount of miles or just a few heat cycles or what?

we(whitefoxgt and i) did my 3.73s, i drove home relativly nice to them, prolly a 10 min ride, then we took both cars out and lined them up

^ sounds good, i'd atleast run a heat cycle or go eat somewhere before i ripped on it.

i'm a little more paranoid, I went about 100-150 miles before i started getting on it more, no whine for me!!

oh well, better safe than sorry

50-100 miles... the big thing is getting heat cycles

I drove like 500 haha. That was the magic number back then on the forums. The trends change...

I honestly this the area where you live has a lot to do with break in due to the diffrent conditions we live in, me i would say 100-150 b/c it's hot humid and you get plenty of cycles.

where Jmac lives, i would say 250-400 depending of time of year... during winter time i would say closer to 500...(it's cold as ***** there)

where subotai lives (tejas) i would feel comfortable saying after 50-100miles you could romp on it...but remember the big thing is heat cycles for the break in
