Shoe area doubled

Following the conversion of the pulley to KOSO's PowerKit, the clutch was also converted to a SPORTReinforced Clutch. when the PowerKit was converted, the RPMs were too high for normal city driving and the vehicle speed was not increasing after 100km. We changed the center spring to AdvancedPRO, the weight roller from 16g to 18g, and the pulley boss +0.5mm to the same length as OEM at the same time.
As for the Clutch, the first thing to notice is that the shoe is much larger than the OEM version. The material also seems to have a good bite, and is considered to be much stronger against slipping. The Clutch Spring seems to be a little stiffer.
The clutch spring has been strengthened and the clutch in has been increased by 500 rpm to 3000 rpm compared to the OEM. I think this is the benefit of this change, but the data from the acceleration test up to 20km/h was slightly better. I thought it might be jerky and difficult to handle at low speeds, but it was not to the extent that I was concerned about it. The weight has not been reduced, and there does not seem to be any dramatic change compared to the OEM. Conversely, I can say that there are no strange Minus aspects.
Since the manufacturer recommends replacing the clutch outer at the same time, we plan to finish this drivetrain custom by replacing the clutch outer at the end.
