The M "Mobility" kit is a bad joke; a can of "Fix a flat" would be just as effective. For many situations (bubble in the tire, total blowout, bent rim) the M Mobility kit is completely useless, and for those where it can be used, it causes as many problems as it solves (you need to get the goop off the wheel, etc).Pinecone said:Then just use the M Mobility kit.
You have a choice, call and wait, or use the kit.
Also the reason for the larger muffler is better performance. Less back pressure.
Another thing, all the current Ms use different wheels front and back with different offsets. Also Limited Slip Differentials don't like different diameters on the same axle.
Lots of reasons why a spare tire would be difficult.
There are a lot of tradeoffs that could be made in the name of better performance. Why have windows that roll down? Even in M models, there needs to be some appreciation of the fact that this is a street car, not a race car. Besides, I suspect that "low backpressure" could be acheived without the giant muffler on the Ms; free-flow exhausts are commonplace, and typically take up *less* space than more restrictive exhausts, not more. Moreover, if I'm not mistaken, all of the Ms use a true dual that Ys into four tips; even if a true quad exhaust were somehow superior to a true dual, the Ms don't have one. The four exhaust pipe thing is ///Marketing at its finest, and is an example of function following form.
