Seriously though... I think the general expectation is that the weight gain is mostly in the front because of the heavier block, heavier cooling system, etc of the S55 and the fact that (the engine) is the only really significant change... as well as the associated exhaust, of course.

Lighter manual seats are a need for both the M2 and M2C.

He's right. Stuff an N55 under the hood.

Then you have an inferior front mount air to air cooling. No thanks the additional equipment is a huge upgrade.

Yeah, also the MPE retains the secondary cats and is still dual path. The ActiveAutowerkes midpipe posted earlier in this thread is single path and deletes secondary cats(easily another 10lbs plus savings).

OEM Exhaust Weights
Full System: 69lbs

M-Performance Exhaust Weights
M-Performance Muffler: 14.20lb
M-Performance Midpipe: 22.25lbs
M-Performance Carbon Fibre Tips (ea): 1.0lb (x4)
M-Performance Hardware (ea): 2.35lb

Combined Weight: 42.80lbs.

Important: Note that the M-Performance is a "Cut and Clamp" style, retaining secondary catalytic converters while keeping emissions compliant, which on the downside, retains a slight bit more overall weight when clamped to the remaining part of the OEM system. Unfortunately, we were unable to get a total weight before installation .

Just as a comparison:

Akrapovic Exhaust Weights
Slip-On Section/Silencer: 29.5lbs
Connecting Pipe: 14.0lbs

Combined Weight: 43.5lbs (25.5lb weight savings over OEM)

Agreed. It was a tongue in cheek response. Happy hour had me by the balls.

Has anyone weighed the stock N55 M2 exhaust(including midpipe)?

Another way to save weight is to only fill you tank with up to 2 gallons of gas.

13.7 gallons of gas weighs @ 84 lbs
2 gallons of gas weighs @ 12.4 lbs
weight savings = 71.6 lbs

How much weight would it really take to "feel" the difference? On the streets? On the track?

I would think it would be a lot (like more than 200 pounds)...but I honestly have no idea.

Is there anymore info about the particulate filter BMW is beginning to put on petrol cars. The M4 will get it soon. M2C will have the filter from the beginning. I know the BMW diesel particulate filters are quite large piece and heavy. I also seen a couple people on 2ertalk say the US bound M2C won't be fitted with a particulate filter and that is the true reason the first build allocations are going to the US. Not because they want to release the car at the same time in all countries.

Surprised lots of talk on weight reduction when no one has driven it yet and are prepared to spend hundreds if not thousands putting it on a diet. The extra 55kg is similar weight to my daughter sat in the passenger seat.....thought it best not to use the wife as an example I don’t notice a big difference. I can’t see M division taking a step back when it comes to handling. Performance in a straight line we all know it will be quicker than the current M2 in particular 100kph to 200kph but by how much

[Karmic Man]

Lots of carbon options from M to save weight now...lol

BMW released their dietary program today... It is called BMW M Performance.

Another way to save weight is to not step into the car.

The OP is about using the M2C specifically on the race track. Regardless of the M2C's stock capabilities, it or any car will perform a lot better when lighter. I think many here can attest that it's also simply more fun to drive a lighter car. Having daily driven an older 2850lb 380hp 2-seater car for years, it feels that we've gone backwards. And of course, lighter cars than that are even more raw, road-connected and fun to drive. Over the years, safety and comfort won out apparently.

I can't see significant factory-made weight losses in the near term until CLAR makes its way down into the 2-series chassis. A more purpose-built CSL may be offered at that point. They may look nice, but even if you got them all installed, the M-performance carbon parts really aren't going to make a big difference in weight - probably about the same difference as BMW removing some of the sound deadening material from the standard 2-series.

Very likely a lot of the current M2 owners opt for *ultimate* weight saving on the M2 Competition: not buying the M2 Competition.

They didn't opt for anything. That was their only option. Curious how many of the current M2 owners would have "opt for" the base M2 if these two had been offered together.

It's not about the past. It's about now: if you got an M2 for the moment, keeping it or do you consider trading it in for an M2 Competition ?

It seems that most over here prefer keeping the ship at bay (and of course finance and timing are important parts of the equation): see here ("Those already having the M2: trading in for the M2 Competition ?").

I don’t disagree a diet gains you performance. If it’s to be used as a track car part of the time, remove the rear seat, passenger seat, carpets, door cards, and drive it to the track cost free option, you could always refit. my thinking is when you don’t remove items but exchange for light weight components it will cost a significant amount of money. I’m sure there is no right or wrong light weight components vs component removal

When you said "opting for not buying the M2C", it sounded more like (to me) as if they had an opportunity to make a choice between these two cars when they were making their car buying decisions but I see your point now. I think many people who are planning to keep their M2s are doing so not because M2C weighs more or sounds worse but because they don't want to take the financial hit, which is quite understandable. If I already had the base M2, not sure whether I would upgrade to M2C or not but I'd be very tempted.

I agree.

Let's face it, an M2 trade-in for an M2 Competition right now, would be more emotional-driven decision-making, than rational-driven decision-making. Most will take a financial hit on the existing car and risk to get sucked deep into the options and M Performance Parts wormhole for the new car. Allow yourself to give it some thought, sleep over it and consider the things that matter most for you (the balance of interests, trade-offs, equation, etc.). Yes, it's all pretty personal. And what about the emotions surfacing when a nicely kitted out M2 Competition passes by ? Well, that's one of the trade-offs for the more rational-driven decision to keep the current car.

Many moons ago, when I pitched the 'M2 to M2C' trade-in idea to my wife, she asked me straightaway: "Wait a sec, is there anything wrong with your car ?". Kinda says it all (also about my wife).
