I put 15mm spacers in th front and 10mm in the rear.
As you can see, there aren't much difference with or without the spacer as far as look is concern.
Front is 20x8.5 with +37offset (with spacer= 20x8.5 +22 offset)
Rear is 20x10 with +35 offset (with spacer= 20x10 +25 offset)
I tried putting 15 mm spacer in the rear but it rubbed. I did not think it would since SC430's can take up to _x10.5 with +29 offset in the rear which = _x10 +17 offset.
no....... 10.5 +29 = 10 +23 man, you did the math wrong 
that's why you can't put 15mm in the back!!!!!! your rear is maxed out already!
anf for the front, you can still go 5mm more easily if you want

I thought 1 inch=25.4mm so 1/2 inch will be 12.7mm.
Here is how I calculated.
10 +35 with 10mm spacer sould be equal to 10 +25.
10.5 +29 offset = 10 +17 offset since 1/2 = 12.7mm
Where did I go wrong? Educated Me
yup, it's wrong. you forgot that when you change from 10.5 to 10, the mid point of the wheel is changed too. and offset is based on the mid point so instead of minus 12, you minus 6 only
draw a diagram, you will know

Looks MUCH better. Wheel offset can make or break the look of a car as far as I'm concerned; I noticed it right away.
Rom is right; 20x10 +23 sits the same (relative to the fender) as 20x10.5 +29.
The center point of the wheel changed 6.35mm when the wheel became 1/2" (12.7mm) wider.
Add it all correctly and it works; it's a little detailed to properly explain here...
