The brand is actually called Spec. Spec Stage 2+ is what I recommended for you. The CDV Delete should be one of the first modifications to these cars for a manual.

The 335i and 335is clutch both have a bad pressure plate although the 335is clutch can handle more hp. The pressure plate seems to fail around 40k miles (mine failed at 45k). Personally I got the Spec Stage 2+ for OEM dual mass flywheel (being installed as we speak). It’s over-power-rated for my performance goals, but I plan on keeping the car for a while and don’t want to swap the whole OEM clutch again in 4 years because of a pressure plate. Bonus is that Spec sells just pressure plates on their own so you can replace just that if need be.

It's a bit common to see the pressure plates not being able to hold up to the torque. Good move on the Spec Stage 2+
