So, my wife is complaining about how aggressive the car is so I have no choice but to change it out again. I'm sick of hearing her wine like a baby. I love the feel of it, but I dont like the way my head pounds after the wife is done complaining. I will be pulling it within the next few weeks, I live in the GTA, for sale for $350. I just picked up a stock 2010 Diff with LSD. if somone wants it I will be more inclined to swap it out faster. Let me know.

The new 2010 ISF diff is in and first impressions is that its stock. I feel the car has lost its wild kick *** side of it. No matter what the specs say I cant see how the only beneficial gear in the 350 diff is first gear. The car feels dead now. Anyways, it has LSD. Thanks Defcon racing again for a flawless install.

My experience is the same as yours- the diff makes the car feel like it's in sport mode all the time. In manual mode, even at part throttle, the tires spin when changing gears.
I might be heading up to NED next weekend. I'll be sure to post results if I do.

You're not going to believe it but there were two brand new wrecked 2010 ISF's. The cars fell off the delivery truck back when they were new and the insurance company wrote them off. The salvage yard I bought the diff from has two engines, two trannys, two diffs two everything. They parted the cars out then crushed them. When we drained the oil from the diff to replace it, it was crystal clear. Visually, the diff is in perfect condition and mechanically perfect. This yard still has the second diff........

Interesting concept here, one would think that if you can get the car to hook up and go it *should* go faster at the track.
Of course, 2 more shifts at .1 each is gonna slow you down .2 right there.
Gear swaps is one of the first and most common things on mustangs and guys can drop .3-.5 tenths off their 1/4 mile ET but they are also set up pretty horribly.
For example, the 94-04 Auto cars were 3 speeds with overdrive. You would go through 3 gears in the 1/4 with stock gearing, and jumping from the stock 3.08 or 3.27 to 3.73 or 4.10 you would still go through 3 gears, just have a way better 60 foot and actually cross the line a lot closer to where you should be in 3rd gear.
I have a drag simulator that I use online sometimes, although it may not be 100%, it is interesting seeing what it says.

I would think this would be fairly accurate, the car should get out of the hole and 60 foot a lot better.
As long as it worked the way it should down the track it should be quicker
Has anyone actually tested this yet?
