What's the best LSD diff for 325iC in the city?

[CabbE30]

Because you can accelerate faster? Isn't that the whole point of almost ever performance mod? If you don't go on the highway much, might as well get a 4.10. It'll be better in the city.

Disregard this guy. He isWrong.

As a 4.10 user for 2 years, going to a 3.73 LSD was the best decision I made in terms of economy and daily driveage.

I hate my 3.73 on the hwy, its at around 3000 going 80 in 5th gear. Im looking for something higher like a 3.25

i have a 2.7i and the 3.73lsd is perfect......feels hella short after the pig of a 2.93

3.73

4.10 is dumb lol

[Vivek]

That is a better approach, but shorter gearing definitely makes a car "faster" in everything except top speed.

[JinormusJ]

If you want a faster car; build a better engine

[Vivek]

That just fuels the insesent need for guys to think their pee pee is bigger than it really is

Unless your purpose building the car as a track car that actually NEEDS quicker acceleration, don't go with a 4.10.

Stick with stock gearing
3.73 for 5 speed
4.10 for 4-speed autos

5 speed with a 3.73

I have a 4.10 that's about to come out of my vert. I don't mind it at all, just changing it up. PM if you want it! I'm by Vacaville, so pretty much local to you.

To flyboyx, my 4.10 shows as an option thrown in on my window "sticker" from the dealer.

my vote would be 3.46. my mtetch2 came from the p.o. with a 4.10. i find it annoying as fuck on the highway. it runs 3200 rpm at 70 with 215/45/17 tires.

all m20 cabrios came from the factory with a 3.73 as far as i know. i have owned 5 or 6 at this point and all manuals and autos had that ratio in them.

[Killacortes]

I vote 4.10. People think its too short but its really not.

[bastianshaw]

is this a 5 speed?
im guessing so
373 gets my vote

[decay]

4,27 in the u.s. in a vert.

in an m20 vert? not if you want to get on the freeway, ever.
