The 135 has aluminium front and rear calipers, the 1M has cast iron front calipers.
I am not even remotely saying the 1M is not a special vehicle, but I am calling a spade a spade. It is a 135 that they threw a bunch of of the shelf parts at, and it works beautifully. Just don't treat it as more than what it is.

1M was not available with a Sunroof. 135i in North America came standard with a sunroof.
The 1m has larger and heavier E92 M3 brakes. They perform better than the 135i brakes however.
The 1M has active steering with an m3 rack. It likely weighs a tad bit more.
The main point was that the 1M has some of the beefier M3 rear subframe and LSD, beefier brakes and additional PPK radiator, but saves weight through some of the m3 lighter parts, shocks, camber links and no sunroof. So even if the two cars are similar in weight, the 1m packs more performance value per lb. |
The 135 did not come standard with a sunroof. I had to pay a considerable amount to add it with the "Executive Package". They just did not make the option available on the 1M.
