Not really. Unsprung weight increases inertia and affects handling adversely. That says nothing about how it affects fuel economy, if at all.

wait, Im confused.
So spending more money on other parts is ok???
Danm, why didnt you say so.........go with 22's.........
you claim that you are using the 'savings' from hypemiling to buy the tires and rims. So are you going to offset the savings from the additional weight to buy brake parts more offten??
You can do what you want, but don't try to claim that the harm doesn't exist. And that the harm has no effect.
On the Q45 site, a common complaint is that the rotors warp and that that is a weak link on the car.
with 235,000 miles, I have never had a warped rotor and I only run factory replacements( which are suppose to be crap). But the guys complaining always seem to be running more weight w/increased rims.
again, your car, go for it. but don't say that there is no evidence of a side effect.
