6MT vs. 5AT ??
I know somewhere here these is a comparo of the 6Mt and 5AT flat out speed differences (0-60, qtr mile, etc.) My neighbor is getting the 6MT and I know he's gonna be gloating (me, 5AT.) Frankly, there is just too much traffic for me to be sawing back and fourth with the MT. I like the Auto. I know I give up some performance (?) how much I don't know. Would be nice to actually know the numbers. I did try and search the forum but no hits on various headers (6mt vs 5at, etc.) I have modded a little with the K&N filter, and ordered the Comptech 22mil sway bar, also using Autocraft 5-20 synblend. Frankly, I think the biggest diff with the two is the 6MT gets the Bremba brakes. Now that's a ding for us AT owners. Also the 6MT has more pronounced torque steer I've been told and a slightly harsher ride. So there are tradeoffs with each selection!

I have a 6MT and I got to drive a loaner with a 5AT. I must say, the 5AT was quite boring for me in comparison. Every day I drive one hour through stop and go traffic in Chicago, but I still don't regret the manual. Once the traffic opens up and on weekends, the manual is great to drive and the control that you just cannot get with an automatic transmission, even in the "shift it yourself" mode.
If you are considering both, I would highly recommend you test drive both and decide for your self.

auto - boring
MT - much more fun, and noticably quicker.
In the G35, I like the auto better.
I still wish Acura and Infiniti shifted the other direction like BMW, and others though. More natural.

I think you got the main differences. As far as flat out, I think the cars are close enough that it will depend on the drivers skill in the real world. The 5AT can pretty much run consistant times. People fail to imagine that they might even slightly blow a perfect shift with the 6MT. If they do, the 5AT will propably win. On those rare occassions that the MT driver shifts perfectly, they will win.

The differences between the manual and automatic are this: the manual has stiffer springs and shocks, larger sway bars, larger brake rotors, Brimbo brakes in the front, and LSD.
I now own one of each.. we just got my wife an '05 SSM/Quartz/5AT/Nav this past Saturday (mine is Anthracite/Ebony/6MT/NAV). There IS a noticable difference in the two cars (besides the transmissions). The manual is a little stiffer and has better turn-in. The ride is generally more firm.

Correct me if i am wrong, but I thought the 6MT's front suspension was a little softer to offset the lighter weight of the car campared to the 5AT. I always thought the inproved turn in on the 6MT was related to bigger front and rear swaybars. Thanks.

To dsc888;
The front and rear sway bars are larger on the manual, and it was my understanding that the springs and shocks were both stiffer.. at least it feels that way between my two TLs. Yes there is a weight difference.. around 80 pounds as I recall with a 1% difference in distribution (manual = 60/40, auto = 61/39).

My BMW handles this bad stuff MUCH better than the TL and I'll guarantee it will hold its own in the saloms against the TL anyday MINUS the nasty ride. Japanese should take note Suspensions ARE important - reverse engineer those german units and make our cars ride 'n' handle better!
Regarding the handling difference, I think that's FWD vs RWD and associated weight distribution differences.
I have been considering adding the Comptech springs and rear sway bar or the A-Spec kit but my car is quiet and I don't want to screw it up so-far.

I've known how to drive a long time. Been driving a MT since 1966 and you? I have also street raced and put in a little track time. Reread the post you responded to and my post #5 above.

However, the 6MT has superior gearing, particularly at higher speeds, and the lighter weight doesn't hurt. From a roll, the 5AT is at a marked disadvantage. I've driven them both (5ATs on test drives and as loaners, I have over 30k on my 6MT) and the 6MT is definitely faster. FWIW, the magazine numbers show a .3-.5 second advantage 0-60 and in the quarter.

I would not be surprised if the difference, on average, in the quarter, was .4 with the 6MT being faster. Most modern sedans have around a 1400 stall converter, maybe up to 1800.
6MT has a 3.93 first gear, that is pretty low.

Comptech Exhaust (+7 hp their dyno claim)
K'n'N air filter - (free flow)
Comptech 24mil sway bar (OK, no speed advantage but flatter handling)
Mobil1 0w20 oil - less friction on engine
Remove spare tire and hardware (less weight)
Tire pressure up to 38 lbs each wheel. (less rolling resistance)
Does that level the playing field any??? Oh sure it does assuming the 6MT is not similarly modified.
