As far as going from 20" to 17"- lots of factors to consider, but the main ones are overall tire diameter, rim/tire weight, and rim offset (aftermarket rims). You can go from a stock 20 to a 17, keeping the overall diameter the same, and you'll have no problems.
Would a dealership or garage do this re-calibration for you?
