Hi all,

Wondering what the weight difference would be between my stock 19 inch 442M's vs a set of 20 inch 405M's? And the difference performance/comfort wise for anyone who has gone that route?

OEM style 442:
F: 8x19" ET36, 13.4kg
R: 8.5x19" ET47, 13.6kg

OEM style 405:
F: 8x20" ET36, 10.9kg
R: 8.5x20" ET47, 10.9kg

That's 10.4 kg for four wheels. If you also change to non run-flat tires there will be additional weight savings.

Did you notice much of a change in how the car handled?
