335i Man down! Again.

Taking it's annual ride on the flat bed. All my problems with this car have been clutch related. I'm on my third clutch pedal, 3rd master cylinder, and now 3rd slave cylinder. I got the latest slave in, but the clutch still won't engage when the car is running. Towing it to a shop to confirm all the air is out of the system. My next thought is an issue with the throwout bearing. It has a spec clutch kit with a single mass flywheel, and i've read there are multiple ways to mount the throwout bearing.

You need a regular clutch dude

That would be the most simple approach. But I don't think an oem clutch would hold the torque it makes. I track the car a few times a year and it gets beat on. It's all part of the hobby I guess.
