If you want a neat look with minimal washing the alloy color will look just nice in the red.
I do however recommend the matte black, as it will go GREAT with you jupiter red color, just make sure the tyres are wet looking usingtyre-shineof some sort, just to give it the distinction between the matte black rims and the wet looktyres. Also with matte black you basically don't need to wash your rims, even if they're dirty, no one will notice unless they're 2 inch of a distance where the eye meets the wheels.
Just my 2 cents.
Can't wait to Mod mine also, but i can't part ways with the amg wheels i have atm, maybe sometime start of 2014 i will change wheels.
