Yes, but the $1,999 unit has a 3.46 ratio, whereas the MT has a 3.08 ratio. A number of people run the 3.46 ratio with a MT for the added effective torque, but your top end & gas mileage suffers. Personally I wouldn't recommend the 3.46 ratio with your MT. The ratios in the MT are short enough as is.
If you decide to go with the 3.46 ratio, keep in mind that it could impact the core charge. |

I find that with my moderately tuned MT 135i, the 3.08 ratio is almost too close to take advantage to the torque generated by the engine. In fact there's more than enough torque to break the tires free in 1st, 2nd and 3rd gear if you get aggressive with the throttle. That's with a LSD and running 265 section width PSSs. If anything, I think I could get away with a slightly taller final ratio and have even considered installing the DCT's 2.81 ring and pinion. |

The ring gear on the MT is welded to the OE differential whereas the AT ring gear is a bolt-on unit. The additional cost is for removing and machining the ring gear.

I think the 3.08 is a good ratio with the right tires, the only think I wish I had with my 3.46 was a taller 6th gear, 5th and 6th seem too close now. |

For the large 215 diff, we have 2.56, 2.81, 3.08 and 3.46 available and in stock, ready to ship, with all final drives (ring & pinions) interchangeable as we have both oem machined and brand new MFactory ring & pinions on the shelf (and we are the only company to offer brand new, upgraded/stronger ring & pinions with the stock oem ratios) For the small 188 diff, we have the 3.46's (oem) in stock as well. Not quite sure where you got your information from, but you are wrong. P.S Those images in the OP are from ECS Tuning, which is not 100% accurate

Just so you know, the DCT has a 2.56, and the 335d has the 2.81
If you have an MT though, the ratios are freely interchangeable.

Maybe? Word of advice; before trying to pass information off as the truth, you should try to get your facts in order first.
And thanks for the apology btw...

For me the 3.08 feels like the gears are way to long but going to a 3.46 may be way to aggressive. Does anyone make a gear in between? Are we allowed to ask how much it cost on here? |

My car is 6mt, fbo+inlets with mhd stage 2+ 91oct. I got the mfactory lsd with 3.08. From my experience, before inlets with 245 mpss, it does feel like i can use more torque from 3.46. But after inlets and mfactory flywheel, i m starting to have traction problem. Now, yes, you can change suspensions/wheels/tires set up to get better traction which = $$. Now my 1st gear almost feels useless, and just zip by so fast. One thing to keep in mine is, no matter what diff you put in, the ratio in the transmission(between gears) will not change unless u get a different or custom geared transmission. At the end of the day, having extra torque is always good, but the problem would be is the car set up to handle all that extra torque.
A fbo+ inlets car with 3.46, my guess would be 1st and 2nd gear would go by so fast, might have a hard time to keep up with shifting. |

I actually think on a modified N54, especially if larger turbos are added, that a 2.81 rear from the 335d would be perfect.
Edit: Old thread and I seem to be repeating myself, haha
