Got a set of cobb ms3 springs: struts?

[Como]

Was fortunate enough to find a used set of cobb ms3 springs. From what I've read so far, these springs are one of the stiffer sets out there. Do I need to go with yellows to be able to dial them down a bit? Or is a non adjustable strut/shock combo still gonna be ok? These will be going on a mz3 hatch. Not a speed. Thx

the front of the car will sit higher due to the ms3 motor being heavier than the mz3 motor.

Ya. I wasn't 100% sure on that. Cobb only now listing one set for both cars. Springs I got came off a mz5. Guy said he was scraping on speed bumps they installed at his work; went back to stock coils.
Didn't want to hijack my own thread but how much heavier IS the disi than the NA mzr?

pending on the mz3 and the ms3 200-300 lbs
