Feel like M235i isn't able to be driven hard
By driven hard I mean mostly stuff like power sliding and donuts. After all, my engine seized at 46k because of doing donuts for like 20 seconds and it threw a rod bearing. Also I've been trying to have fun sliding it in the wet but with the e-lsd and dsc off it just completely spins out with any real throttle input. In sport plus the dtc doesn't let it spin or really slide. And since I have an auto throttle input is horrible as you're either giving it too little or too much and have to step into overdrive. My E39 540 with an open diff was easier to slide and I didn't have to worry about seizing my engine or another major eff up just because I'm having fun with the car.
Are my issues just because auto and no lsd? Or do others feel the same. Inb4 "take it to the track if you want to drive hard". No |

I'm going to assume that you take public safety to heart and perform your donuts, power slides, and other "fun" activities in empty parking lots, especially since you have acknowledged your proclivity for spinning out.
A few points: Completely spinning out indicates that the car is rotating sufficiently to perform a "power slide", I would suggest practicing control. Unsurprisingly, no car is designed to "do donuts". Numerous members on this forum, including me, have tracked their cars and "drive them hard"; oiling usually isn't an issue. Throttle input is the same regardless of transmission. --- In other words, your issues are not because of your car having an automatic transmission and an open differential. |

Does the 6MT also have kickdown? In my E90 the throttle was linear. And I've had fun on windy roads before, even took it to pikes peak, but that's a different kind of fun that's not easily accessible in my area. Still feel like the car is very sensitive compared to others and should have come stock with an lsd

Driven hard isn't really the word you're looking for. More like "M235i can't do donuts due to driver error"

The oiling system on the M235 is pretty robust and rarely do you ever hear of spun rod bearings except on track driven M235s that sustain high G loads for extended periods. For that type of driving, some add the M2 N55 oil pan and pump system. I suppose if you're doing donuts for an extended period (30+ seconds), oil was a quart shy, and you got the oil sloshed over to one side of the pan due to the sustained Gs, then I guess it could be possible to spin a rod bearing. I'd also have to think the bearings already may have had a preexisting condition, especially if you bought used.
As for holding controlled drifts in DSC Off, yeah, it doesn't work well with the open differential and e-LSD. You can induce the drift, but it can be snappy and hard to control as the e-LSD tries to figure out how to control things. The answer is really simple. You need a true LSD. I drove my car with the stock diff for 2 years and then added the M Performance LSD. I've had the LSD for over 2 years. The difference is night and day. The rear is now controllable and like you'd expect in a sports car. Sport+ will only let you hang out the rear a foot or two before dialing back in things. Nothings has changed there. The e-LSD is really quite good, but in no shape or form a substitute for a true LSD. The rear axle feels completely buttoned down and stable. It's like adding 500lbs over the axle. As for the throttle sensitivity, it's due to DSC Off using the Comfort throttle setting. BMW does this so the input is linear and more tractable in track driving. You want it this way in a high torque turbo motor. You get used to it the more you drive in that mode. If you want more throttle sensitivity in DSC Off, buy a Sprint Booster or similar. It will get you what you want, regardless of driving mode.

No kick down with the 6MT throttle. Kick down is for automatics. Kick down in the 6MT is the driver grabbing the gear they want when they want it.

As for the oiling issues, I found the same info about M2 oiling system after my engine seized, maybe I didn't let it warm up enough. It's weird bc another member had the exact same problem as I did within the same mileage. Now I'm just extra paranoid about it |

As for oil warm up, per my datalogs, takes at least 10 minutes of driving to get oil up to a minimum temp assuming the oil was cold. When temps are below 40 degrees, it takes even longer for oil to warm up. It temps are below 20 degrees, the oil may never fully warm up. Doing donuts is hell on any motor. The reason being you're running the engine at high rpms, there's no air going through the radiators and oil cooler, and the oil pan is under higher G's. I couple of donuts is fine. Doing them for extended periods is never a good idea.

You know it isn't the best idea when Donuts aren't good for cars or people ....they sure are fun and delicious though |

I really wish my car had mechanical LSD now lol Also what about rear end gear ratios? I feel like they could be made shorter in these cars right? I always compare my m235 to the r35 GTR and that was one big difference I noticed. I want more acceleration and less top mph. I bought the m235 as a poor mans knock off to the GTR and want to mirror the physics as much as possible.

Ironic how if you own a performance car, it’s considered a waste if you don’t use it. But when buying used people avoid such cars like the coronavirus.

It handled better, got better mpg, had a real Limited Slip Diff, revved much faster and higher, weighed about 900 pounds less. I was so young and naive I bought the "M" marketing hype from BMW lol
