The weight difference, per BMW, is 165 lbs. Many independent tests have shown it to be much greater-- for example, car and driver weighted theirs and found the weight difference to be 230 lbs. Either way it is certainly significant.
Additionally, the 128 is much closer to 50/50 weight distribution, which is much better for handling as well.
I would argue that both brake setups for the 1 series suck, but if I had to chose one, I'd rather have the setup that fades than the setup that catastrophically fails. That said, I wonder if the 128i setup on the 128i is actually more prone to fade than the 135i setup is on the 135i-- less weight to slow it down and less power means less speed to be slowing from. Either way, I don't believe BMW has ever actually shipped a car with good brakes from the factory. All of mine have been upgraded to full Brembo GT BBKs :roll eyes:
Worst case for 128i brakes: fade (probably completely addressable through track pads)
Worst case for 135i brakes: cracked pistons, melted dust boots, fade. If you address the fade with pads, you increase temps making it more likely you'll have cracked pistons and melted dust boots.
High winding, from the drivers perspective, doesn't matter what the absolute redline is. The idea is that you have to work the trans over to stay in the power band rather than just relying on torque. It doesn't matter if that happens at 7000 rpm or at 8200 rpm (as it does in my DD e46 M3).
I come up with a whopping 56lbs(6 speed) using BMW's own data.
Much closer to 50/50 distribution? Really, less than 1% is much closer? You're losing credibilty here.
You'll also take the 128's brakes? Wow! OK then.
