Front and Rear 4 Piston Brakes

[SteveBorough]

The new rotor is 203mm. I needed to replace the caliper adapter (from Magura) to go from 180->203 since the new caliper would not mount on the existing posts. I considered using the 220mm rotor but my fork is limited to a max 203mm. I did some research beforehand and the manufacturer (Suntour) implied I might damage my fork by using the 220mm rotor. It seems too much braking force is not a good thing.

I'm also considering 203mm front rotors for my Superdelite, Amazon has both of these:

Magura USA MDR-C CL​

Magura Storm Hc Disc Brake Rotor​

they are significantly different from each other. Which will work for the SD (MY2021)? Also, do I need the QM42 or QM44 adapter?

Thanks!
