the BRZ felt so much lighter and the steering so much more responsive. The 135i may be 50/50 weight but the straight six hangs past the front axel and then there’s the intercooler in front. They’re kinda understeery at least with the alignment or specs from factory. The power and torque of the 135i is way more than I could ever use on the street. With the BRZ I felt like the on ramps were like an autocross. The sales guy was cool. He’s an auto-x guy and was egging me on to get the rear loose. The limits of the 135i are so high there’s no way I would do that on the street. At times I miss the torque but for me Miata, BRZ, and S2000 are much better cars for the driving I do. Maybe with lighter wheels, M3 bushings and control arms thare 135i is transformed. That’s basically a budget 1M which people rave about. If I did 135i again I’d do those kinds of mods and not the power mods I did.
