Where to buy these friggin replica's?
20" wheels will induce a understeer, actually enhance the understeer we already have. With the enormous 6.2 liter motor over the
front wheels and then a 20" package will really make the handling suffer.
22" wheels are ....well..... I dont know what to call it. its like taking a high performance aircraft and modding it so it can only roll down the runway and not be able to fly.

Just keep your HRE's. Maybe have them refinished or something if you don't like the black lip.
You just can't put replicas on the C63.

I'd sign a waiver that it is my responsibility to not drive over potholes and if I do, I am releasing MBUSA of any warranty claims of driving into potholes.

Understeer is a design feature. Changing wheel sizes doesn't enhance it as long as the overall diameter stays the same. You can combat understeer somewhat by varying the pressure in the fronts when compared to the rears; i.e. F = 29psi and R = 32psi vs F = 35psi and R = 32psi. You now have somewhat less understeer with the latter.
However youre completely correct if the outside diameter doesnt increase. But if you put on heavier wheels and heavier tires just by the amount of mass you have increased in the front you are going to increase turn in time and understeer thats just physics. We had the SAME problem our our Porsche GT3s. The stock 19s were too big for the design and on the track we had a terrible push mid turn. The typical 911 18' rims almost immediately corrected the problem. Also the ride quality is enhanced with the smaller rims. A bigger rim and tire combo with increase harshness.
Paascheo The reason AMG is not putting on the 19s here is because they say that our roads are too RUF for their lightweight wheels.
If you arent a big time tracker dont worry about it one inch isnt going to be a big deal HOWEVER you still might notice a harsher ride.
