i'm not really that stressed about the appearance, if production pieces are better, then great. i'm more interested in performance, and when i see a single inlet going into a muffler, then 4 outlets, the only assumption i can make is that there will be a lot of turns (creating back pressure) in the muffle case.

m3 adjuster, since you seem to have the insider info on the car and are very closely connected with m engineers, will they change the design of the muffler? please do not take my assumptions or questions as an attack on you.

But like I said in my earlier post in this thread, BMW makes non-EDC versions of ZCP shocks for both the E92 and E90.

I'd be interested in any documentation (scan perhaps) that came with those EDC versions. Especially regarding the drive signal specs (digital or analog, levels) to the shocks.

The relation could be a little higher than zero, not?

Absolutely! My apologies to all for the rant, just hoping to keep things factual so that people don't get upset later. We already have people upset about no cf roof things like fender slits and i can see people already seem to be making decisions about ride height etc.

Sorry I have no idea on the exhaust. I'm not currently connected to anyone at BMW M, I just was able to see the preproduction cars and can relay what I saw and heard then.

M3 Adjuster - voice of reason. How many times have we read press reports of pre-production cars being rough around the edges. Select journalists drive these early release cars and I am sure their comments are noted by engineers who may make changes for production. I don't care if it is a parts bin special as long as the parts are good ones - yes? Patience my friends.

The shocks came with no documentation, and looked more or less identical to my old non-ZCP shocks.

Here's a pic of the ZCP shocks:

This car would be amazing if it had the S54, why god...why didn't they use the S54 in this car. I'd totally get one...

Most people with a "faster" DCT will crank out SLOWER lap times against a good driver in a "slower" manual.

I wont even get into the boring part that someone else pointed out, but Id rather row my own gears and give up the 0.12 secs or whatever it is the DCT gives. In the end its negligible.

all this hype but its got amber lights...lol

very very very nice.

Although you can see a rectangular patch spot welded on in the very last picture I strongly suspect BMW M did not mess with any sort of stock or preexisting muffler. BMW began working with its supplier (or suppliers) of choice on the full sound level, sound quality, flow and back pressure specifications for this muffler long ago. If BMW wanted any adjustments the supplier would do the modifications, not BMW M. Either way the production units won't have that patch. It still will have some discoloration at welds since that is just what stainless steel often does.

Hmmm, not to turn this into another MT vs DCT debate... But ...

I've corrected your statement. No quotes are needed in the speeds because the speeds of the transmissions are not in question and it is clear that the speeds refer to the trannies not the cars. The "Most people" part is the totally false part that really struck me.

Thank you.

Enough said.

I don't think you can say that drivers will deliver better laptimes with DCT. There are many more variables to consider.

These pictures look really great! So much better than the ones at Detroit!

[Mak135i]

I saw the 1M at the Chicago auto show last night. I asked if there were going to be changes made to the production version. The people working at the BMW stand did not know. From the quality of the interior, I would hope so.

[vasillalov]

The real question is whether the LSD will be a direct swap for 335i and 135i....

You didn't actually expect the reps at the car show to know more about it than we do, did you? Most of them are sales people from the area dealerships and work off of technical specs. (Typically)

The interior is probably the same as production. The car in Detroit felt exactly the same as my 135 except that 1,000's of people had gotten in and out of it before me.

[Mak135i]

I did expect the BMW reps. to be knowledgeable. This was the 1st night of the show. Black tie event, by invitation only, so I thought they would have their "best people" there.

The car was probably the same one they had in Detroit. The interior was not the same as in my 135iC. The switch gear seamed more flimsy and cheap in look and feel. There were others there (a couple of 135i owners) who made the same observation.

My preference isn't about trackin a car. Daily drivers have to be just that, daily drivers. I'd be curious to know how old the guys that want to use these cars as a track runner vs the ones that want the car to be a fun daily driver. Not that you can't be one or both, but I think it would prove my point.

Buy the car and do a motor swap if you love the s54 so much. I am sure you can sell a brand new n54is motor for far more than the 4-6k it would cost for a used s54.

. If it were, people would probably already be doing it. The diff comes from the m3, but the 1m also has the m3 rear subframe which the diff mounts to.
