On the rear, it’s generally a spacer on DS only, requiring a re-dish and a spacer for rotor...eh? With something like a Problem Solvers kit you shouldn't need to - spaces either side out 5mm (with a spacer for 6 bolt rotors too). https://problemsolversbike.com/products/brakes/booster_-_k5143
Unless you've got a 10mm spacer only on non-disc side?
