Even the shocks and struts are aluminum vs steel on 135i but the 1M is also carrying bigger wheels and tires, bigger brakes and a full lock differential, bigger exhaust, quicker M steering rack as well as an additional radiator with extra coolant. So even though many say 77 lbs is not that much. It is 77 lbs plus bigger and better hardware on top of it. There is less insulation and even the flywheel is lighter!

Hmm, the numbers I quoted were originally taken directly from BMW's German site.
Both the 1M and the 135i have an aluminium front subframe and a steel rear subframe. Also, after having switched all my front and rear control arms to the 1M version, there really is no difference in weight. The rear front and upper arms on the 135 are actually probably lighter, but the rear camber arm is a little lighter on the 1M. Makes is pretty much a wash, or a 2 or 3 lb difference total.
