I would get the tyres off the rims, then buy 1 pair of 20mm spacers.
With just the alloy wheel without the tyre it will be a lot easier to work out how much spacing you will need, you can swap the spacers front and rear just as a starting point to work out the correct offsets that will work for you and go from there.
I just did a tyre size comparison check from what i running now to what you have got
Mine 245/40/19 = 26.7" diameter
You 245/35/21 = 27.8" diameter
So the 21's will fit in the arch it all depends on the correct spacing.

Given what you wrote in your first post then your fronts would be ET22 and rears ET32
9x21 vorne 245/35R21 Reifenpreis bei ReifenDirekt.de anzeigen ET 22 18,20
10x21 hinten 285/30R21 Reifenpreis bei ReifenDirekt.de anzeigen ET 32 18,85

Would a tire downsize fix the issue?

I can't believe you're still trying to make those 21 inch wheels fit!
Even if you're successful, you're not gonna to love the ride.
