OFFSET HELP: Preparing W204 to W205 Transition




OVERVIEW:
I need some help from the offset experts. I'm running stock wheels on my 2009 C350 and about leap to 19" wheels.
In 3 years or less, I'm going to move to the C43 W205. I want to avoid having to buy new wheels. I want to swap these over.
The dealer has proposed: 19 x 8.5 40 Offset, 19 x 9.5 42 Offset.
I checked using the offset calculator and it looks like this can work.
Question: How will this be ride quality wise? The rear seems on the low side...
Thoughts? I would appreciate some input.
