I recently bought five FR premium cars, all in the same general class: a 350Z, Mustang, RX-8, S2000, and 135i.
See, I'm cooking up what could be an online racing series. So I "race prep" each car a bit. Everybody gets upgraded exhaust, clutch, stiffening, flywheel, windows, racing hards, etc. Then, using weight reductions, tried to make them so they all weigh about the same. So far no power mods, but that's coming up.
And of these near-equal mods to each car, let me tell you: the Bimmer was by far my fave.

Sublime handling, great accel/decel, stable... Great car. Nine seconds faster around Nurb GP that the slowest, the S2000 (which,by no coincidence, has the least power

).
You could argue that I like it best because right now, it has the most power of the five. But once I get these cars all clocking the same lap times, we'll see
So what I want to say is that the 135i, with good mods, is a great BMW 👍
BTW, how does this sound as a series? Like diminutive touring cars?
