What diff is in your M42 car?

Please let us know why... i.e. dickweed that wont tell us a 2.73 works great! (if turbo'd)

4.10 cause it came w/ the car ;)

No 3.64 makes baby jesus sad.

Oh yah, 3.64 small case because it was $40. I was looking for a 3.73 LSD medium case for a while but I never found one at the right price.

4.44LSD

Got a killer deal on it. Gives the car a little more "pep," and I don't have to downshift as often.

4.27 coz our speed limit is 60mph nd i dont go to highways much, the road to my university is an uphill so its workin gr8 4 me, plus its responsive on the streets :D

[Hick]

go as close as you can, polls only allow for 10 selections

[revhard7]

its all about how u drive nd where u drive...

I put 3.73's in both of mine since I drive 126 miles round trip for work. Driving between 70 and 75 puts the rpms just over 3k. Much nicer then 4k with a 4.10. I definitely wouldn't go any lower since there are a few hills along the way between Sutherlin and Eugene that the m42 would really struggle on.

4.1 LSD but would be interested to try a 3.73 just to see how much acceleration I would lose. I do a lot of freeway miles for work but I do autox too so . . .

3.73 lsd couldn't stand the 4.10 open but I'm turbo so...

4.10 since it's stock, but I'm looking for 3.25 or 2.93 to get uber MPG's on my long drives.

Its better for the autox IMO. 2nd gear runs out further, dont hit the rev limiter as much as i did with the 4.10

80mph w/ 410 = 4k,
80mph w/ 3.73 = 3500

win win

4.10, but I'm in the market for a 3.73 because of the turbo; it runs out of gear reallllyyy fast right now.

You have more torque and horsepower going to the wheels at any given with a shorter diff though (assuming you're in the same gear). I've never been at an auto-x where I needed to shift up to 3rd.
